Apart from passing hearing screening, there are also signs that you can watch out for that indicate your baby’s hearing is intact. Expected milestones within the first year of life include:
Birth to 3 months
Is startled by loud sounds
Makes soft sounds (vowel sounds aah, eeh)
When spoken to, they calm down or smile (ssh)
Recognizes your voice and calms down if they were crying
4 to 6 months
Turns the eyes towards the sound
Makes bubbling sounds
Responds to tones of voice
Responds to music and pay attention
Seems to enjoy toys that make sounds
7 to 12 months
Looks and turns toward the direction of the sound
Responds when their name is called without the voice being loud
Listen when spoken to
Responds to simple requests or commands like no, come, go, bye.
Looks at things you refer to e.g., a picture, toy they are familiar with.
Begin to imitate sounds and say names like ma-ma
Babies at a high risk of hearing loss
A baby may be at high risk of having a hearing loss if:
They were born prematurely
They stayed in the NICU (neonatal intensive care unit)
They were treated with medicines that could cause hearing loss
They had complications at birth
They had frequent ear infections
They had infections that could damage their hearing such as meningitis or cytomegalovirus
Why do newborns need hearing screening?
The sole purpose of hearing screening is to help to determine if a baby may be deaf or hard of hearing. If the hearing screening is not done, it will be difficult to tell when changes in the baby’s hearing are occurring within the first months and years of life.
Babies normally get startled by sudden noises and turn their heads towards the sound, for example, but this doesn’t mean they can hear all the sounds happening around them. Even babies that are deaf may hear some sounds, but not enough to understand what has been spoken.
Babies that are hard of hearing or deaf need early interventions, support, and care to promote healthy development. If hearing status is not identified, the necessary support will not be given, and this will lead to the baby’s communication skills being negatively affected.
In the long term, if hearing loss was missed, it would impact the child’s academic ability and social-emotional development.
How hearing screening is done
Data from CDC (Center for Disease Control and Prevention) shows that over 98% of newborns in the United States receive newborn hearing screening.
There are two screening methods that are normally used: Automated Auditory Brainstem Response (AABR) and Otoacoustic Emissions (OAE).
Automated Auditory Brainstem Response (AABR)
This screening involves measuring how the hearing nerve and brain responds to sound. Soft tones or clicks are played through earphones into the baby’s ears. Three electrodes placed on the baby’s head then measures the hearing nerve and brain’s response
Otoacoustic Emission (OAE)
The screening measures sound waves produced in the inner ear. A tiny probe is placed just inside the ear canal to measure the response (echo) when clicks or tones are played into the baby’s ears.
Both screens are painless and can be done while the baby is sleeping or lying still and usually take about 5 to 10 minutes. Either screen may be used or both.
What to do next if your baby didn’t pass the hearing screening
Step 1. Follow up with an Audiologist.
If your baby fails the initial newborn test, rescreening is done, then diagnostic testing. The diagnostic testing is most accurate. Your pediatrician will refer you to an Audiologist if a hearing impairment is detected, and more follow-up testing will be done before the baby is 5 months old. Interventions are then provided before the baby is 6 months old for treatment to be most effective.
Step 2. Early childhood hearing interventions
If the diagnostic test shows your baby has a hearing loss, you will need a team of early interventional professionals to guide and support your baby. They include:
Otolaryngologist (ear, nose, and throat/ ENT physician)
Family- infant teacher
The main goal of this team is to help your baby achieve their individual fullest development potential as possible.
Your child can be given a hearing aid if he has sensorineural hearing loss. This hearing loss is usually the most common. Hearing aids have three basic parts: the receiver, microphone, and amplifier. The settings of these components are normally customized to make certain sounds louder. Some hearing aids can be worn on the body, and others are fitted behind the ear or inside the ear. The doctors will guide you on which hearing aid suits your child’s needs.
Hearing aids make sounds louder for the deaf child.
Because of the technology used to develop them, hearing aids are expensive. You might find some health insurance companies cover part of their cost.
FM system (auditory trainers)
It is a unique amplification device that is designed to help school-going kids. The system has a microphone that the teacher speaks into and a receiver help for the child. They send the sound either to the ears or to a hearing aid. FM devices improve hearing in a group or noisy environment. They can also be used at home and also work well for older kids.
Hearing rehabilitation works on developing and improving the child’s ability to communicate. They include auditory therapy, listening therapy, and speech (lip) reading. Technology is coming up with new inventions by the day; your specialist team will guide you on the best tools that will further aid in your child’s communication.
A cochlear implant is surgically placed into the inner ear to send sounds directly to the hearing nerve. This treatment does not cure hearing loss, but it is very effective for children with profound hearing loss who cannot be helped by hearing aids.
Is my child deaf or ignoring me?
If your child doesn’t seem to pay attention when you are talking to them and sometimes are forced to keep repeating what you are saying to them, it is possible they are ignoring you, or it is a hearing impairment.
You can tell they are ignoring you if they seem responsive to other sounds, like music or TV. However, if they don’t seem to respond to sounds or they ask you to repeat what you said to them, or you have to be loud for them to listen, it might signal hearing impairment, and you need to have a pediatrician check them. If they are school going children, their teacher will also notice and raise this concern.
Baby passed hearing test but doesn’t respond to sound/signs of baby hearing problems
Sometimes babies who pass the newborn hearing screening go on to develop hearing loss a few months or years down the lane. Progressive hearing loss or late onset can happen from a lot of factors such as infections, e.g. Measles or meningitis, head injuries, exposure to loud noises, secondhand smoke and more
So, even if your baby has passed the newborn hearing screening, you still need to watch out for possible signs of hearing loss as they grow and discuss them with your pediatrician. Some of the signs to watch out for include:
The baby doesn’t startle at loud noises by the time they are 1 month old or turn toward sounds by 3-4 months.
The baby doesn’t notice you until they see you
The only sound the baby concentrates on is vibrating noises
When you read to them, they don’t seem interested or to be enjoying
If the baby has delayed in beginning talking, has difficulties understanding, or hasn’t said single words like ma-ma or pa-pa by the time they are 12 to 15 months old.
Doesn’t respond when called out to from another room
The child wants the TV volume turned up than others
The child appears to hear some sounds but not others. (There are variations, some children only one ear affected by hearing loss other times the hearing loss affects only the high pitched sounds).
The child sits slowly or cannot walk unsupported properly or has trouble keeping and holding their head steady. (It happens in children with sensorineural hearing loss if the inner ear part which affects balance and movement of the head is also damaged)
Do deaf babies cry differently?
Crying is the first way babies are able to communicate, and all babies cry for the same reasons, either they need something or they are having discomforts. All babies’ cries are usually inborn or instinctive. They are therefore not affected by external factors except those that affect brain development like prematurity or injury, the larynx or if the mouth is affected like having a cleft palate.
So, deaf babies and hearing babies cry the same the only difference being the deaf babies cannot hear themselves.
How to Test Baby’s Hearing At Home
As earlier discussed, earlier detection is key in treating babies with hearing impairment so that they can develop normally. However, we know that not all mothers around the world are able to access hearing screening services for their babies. Even in America, where almost all babies receive the newborn hearing screening, 45 % of parents with babies who need repeat screening after failing the first do not return.
The good news is, every parent with an iOS smartphone or tablet can download a free app created by Eric Kraus, MD, surgeon in otology and neurology, and screen their baby’s hearing at the comfort of their own home.
The app is called the Sleeping Baby Hearing Test App and is available free from iTunes store. It features an inbuilt, self-calibrating sound level meter that measures voice volume. This allows a mom to gauge the loudness of her voice while speaking the Ling 6 Sound Test while the baby is sleeping lightly.
The 6 Ling sounds are (“ah,” “oo,” “sh,” “sss,” “mmm,” “ee”). The mom will be repeating the sounds at 60-70 decibels within the first five minutes of the baby falling asleep in a quiet room.
For this screening purpose, only the mom’s voice should be used, and not the father or any other speaker because babies are mostly in tune with their moms’ voice.
Babies aged 2 weeks to 6 months will arouse and respond when the mother speaks. This indicates the baby’s hearing is intact or is at least working properly in one ear. On the other hand, if a baby fails to rouse repeatedly, it could indicate a hearing impairment, and parents should seek additional professional hearing testing for the baby.
If a baby has been using hearing aids, the Sleeping Baby Hearing Test should be performed at home when the baby is wearing them. If the baby arouses when the mom speaks, it is a positive indication that they are providing the desired benefits.
How do deaf parents know when their baby is crying?
There has been a lot of interventions used from ages past by deaf parents to be able to tell when their baby is crying. These included sleeping in the same bed with the baby, so they can detect movement, other times using a trained hearing dog to alert them, and more. These interventions were limited compared to today, but babies still thrived.
Nowadays, the options are plenty. Deaf parents can use baby monitors, smartphones, flashing light and mirrors, and the old age, most reliable option, which is simply looking at the baby.
Baby monitors– there are various kinds of monitors in the market for deaf parents such as; audio baby monitors, vibrating baby monitors, video baby monitors, and others that can do all those functions. The most favorite among deaf parents is the vibrating monitor or a camera baby monitor or monitors that combine both functions. You will be interested to learn that there is even a baby monitor that can be connected to a vibrating alarm clock which causes the bed to vibrate, waking the deaf parents if they are sleeping.
Smartphone apps– you can use FaceTime, for example, to observe your baby when you are in different rooms by placing an iPad facing him while you use the iPhone.
Flashing light– they have always come in handy in alerting the deaf of fire alarm, a phone call, doorbell, even a crying baby.
Mirrors– these can be used perfectly while having a car ride, for example, where a deaf parent can be able to observe the baby.
Trained hearing dog– hearing dogs also assist the deaf parents by physically alerting them about alarms and sounds such as the doorbell, smoke alarm, telephone call, and the baby’s cry. Some deaf parents get hearing dogs from donating organizations such as PAWS or buying the dog, which is extremely expensive.
Baby Cry Monitors for Deaf Parents
The most common cry monitors for deaf parents use the following modes:
Vibration alerts, light alerts, extra-loud sound, and combination of vibration, light, and sound. The four modes have been proven effective in alerting deaf parents when the baby needs attention.
They cause vibrations on the parent unit to notify the deaf parents and usually differ in strengths. Some of the best vibrating monitors include:
Summer infant babble band wearable audio monitor
Sonic alert sonic sitter baby cry signaler
VTech DM 221
VTech DM 223
Philips Avent SCD570
Graco Secure Coverage
Audio baby monitor timeflys
Baby monitors with LED lights alert
The monitors are also ideal for parents who are totally unable to hear any sound. To use, you turn the parent unit to face upwards where you will be able to see the LED lights flash when the baby cries. Some monitors have the LED levels set in a way that also matches the sound level. For instance, from a scale of 1 to 10, a LED level of 10 would mean the baby is crying very loudly and screaming while 1 or 2 the cries are just soft or wimps. Because of these variations, deaf parents are able to respond to the baby accordingly.
One major disadvantage is that the LED lights are ineffective in situations where you are not able to see the light coming from the parent unit or asleep. To solve this problem manufacturers have developed monitors that combine light function and vibration.
Baby monitors with lights, vibration, and sound.
These are the most ideal for deaf parents because it gives them two options, so they don’t miss any cry.

If you’re reading this post, you probably ended up here as you look for ideas of how your unborn baby will look like once you deliver.
I was very anxious about this too and this article will guide you to what you can expect your baby to look like depending on a few predictable features. For example, if your baby’s father is of the white race and you, the expectant mother, is of the black race your baby will be half white and half black. This is what I mean by fair assumptions as you guess what your baby will look like.
You also need to make sure that you follow your pregnancy calendar using your due date calculator to ensure that you don’t miss any appointments to the clinic. This way your unborn gets all the attention and support it needs as it grows inside your womb.
The video below explains what your baby may look like:
What Determines How Your Baby Will Look Like:
Recessive or Dominant Genes: Your genes can be considered strong if you have a dark complexion and your genes may be considered weak if you have fair skin
Color of Eyes: If both of the parents have brown eyes, the baby has a 75% chance of the eyes being brown, 18.75% of being green and 6.25% of being blue. If on the other hand one parent has blue and another has green, then the baby has 50%-50% chance of having 50% brown eyes, 37.5% green and 12.5% blue eyes. If one parent has brown and another has blue eyes, then the babies eyes are likely to be 50% chances, 0% green and 50% blue. If the parents have green eyes, the baby has 1% chance of having brown eyes, 75% of having green eyes and 24% chances of being blue eyes, 1:56 of 4:15

According to the US Department of Agriculture estimates, an average baby would cost up to $252,882.90 to raise until your baby reaches 18 years. That’s before the baby goes off to college. Since 1960, the U.S. Department of Agriculture (USDA) has provided estimates of annual expenditures on children from birth through age 17.
Below is a summary of the cost of raising a child you should expect according to the US Department of Agriculture:
For a standard household with two kids, the cost of raising a baby annually $10,099.70 to $10,803.35 when adjusted for inflation. These base figures are from 2015 and adjusted for inflation to get the equivalent in 2019
This translates to about $ 841.60 to $ 900.30 per month to raise a baby.
By the time the baby is celebrating the 18th birthday, you’d have spent at least $252,882.92

Guide To Pregnancy Due Date Calculator
If you want to estimate the due date of your conceived baby, we have worked with 3 pregnancy experts to put together a new and very accurate due date calculator. This tool is one of the many that 10BabyGear has been preparing to support pregnant mothers to estimate the likely date of birth for your baby.
There are three ways to estimate the approximate due date period and below are the options:
Calculating the due date using the last period/conception date
Calculating the due date using IVF method
Calculating the due date using Ultrasound
Due Date Calculator on Conception
The date of conception is your day of ovulation as human eggs can only be fertilized in 12 to 24 hours after ovulation. Whether you are using in vitro fertilization or got pregnant naturally, the due date calculator on conception is purely an estimation based on when you ovulated. While the ultrasound estimation method may provide a slightly different conception date, the estimation of the due date may not vary significantly. This above calculator essentially can be called a when to conceive due date calculator
The estimated due date is the date you expect to go into labor and it is calculated using the formula below:
Due Date = (First Day of Last Menstrual Period + 287 DAYS)
The 287 days is the 9 months gestation period for humans plus 7 days. This is not a method specific or developed by the 10BabyGear team. It is a due date calculator and conception date estimator used by pregnancy wheel. You may have seen this being referred to as due date calculator wheel or due date calculator pregnancy wheel.
Both terms mean the same thing, essentially adding 287 days to the last day of your latest menstrual period. This pregnancy wheel calculator of due and conception date has two main assumptions:
1st Assumption: That the mother has 28 days menstrual cycle
2nd Assumption: That ovulation takes place on the 14th day
This pregnancy wheel calculator is used solely for estimation purposes especially if you don’t remember the last day of your latest menstrual cycle or have forgotten the ovulation date.
Due Date Calculator With In Vitro Fertilization (IVF)
The pregnancy wheel method works perfectly to estimate the expected delivery date when you’re not sure about the day of egg fertilization.
However, if the egg was fertilized using in virto fertilization method, the due date calculator with in vitro fertilization is obtained using the formula below:
Due Date Calculator With In Vitro Fertilization = (Date of Fertilization + 266 Days)
The above formula works if you are having:
IVF with your own eggs
IVF with fresh donor egg cycle
Fresh donor embryos cycles
To arrive at the IVF due date, an IVF due date calculator can use any of the following variables:
Date of your egg retrieval (Fresh IVF)
Date of day 3 embryo transfer (Fresh or frozen IVF) or
Date of day 5 blastocyst transfer (Fresh or frozen IVF)
The IVF due date calculator will give you the estimated date of confinement (EDD)
Due Date Calculator By UltraSound
Ultrasound is the only method among the four we’ve listed in this article that you actually have to visit the doctor. The doctor will use the ultrasound machine to calculate the gestation age and make an estimation of your baby’s due date. The gestation age is the number of days/weeks or months between the first day of your menstrual period and the day the ultrasound test is taken. The American College of Obstetricians and Gynecologists and its Canadian peer have cautioned parents to beware that the due date calculation using the ultrasound method can be inaccurate depending on the gestation age of your fetus. Actually, they recommend specific ultrasound days indicated below:
If you are torn between due date calculator vs ultrasound estimation method, I highly recommend going for due date calculator using conception date to avoid redating the fetus as it may have harmful effects.
The due date calculator according to ultrasound requires you to know the exact gestation age as mentioned above. You’ll then enter the exact gestation age in weeks and days such as 6 weeks and 3 days on the day the ultrasound was performed. I have personally used the due date calculator by ultrasound once during my first pregnancy and I didn’t like it. The process of visiting the doctor, measuring the size of the fetus, estimating the gestation period and comparing the due date calculator vs ultrasound was just too much of hassle to me. The same way I prefer using fetal dopplers/doptones at home to going to see the doctor every other time I want to check my baby’s heartbeat rate.
Is Due Date Calculator Accurate?
To question of whether due date calculators are accurate has been asked by many parents who have been testing the 10BabyGear Pregnancy tool before its release.
There are also several other online due date calculators such as those offered by BabyCenter, the Bump, WhattoExpect and many others. How accurate are all these due date calculators? To determine their accuracy, we carried out a survey with the help of the team at Pregnancy Center to determine the accuracy and below is what we found out
Due date calculators are somewhat accurate and it really depends on the variables you’ve put in. If you are confident about the variables, most due date calculators we surveyed are accurate about 20% of the times.
External studies however disagree and estimate that online calculators are only accurate 5% of the times. For example, if you are not sure about the gestation age, the ultrasound method may not be very accurate and similarly, the due date calculator may return inaccurate results if you don’t know the first day of your latest period.
We have tested and determined that 10BabyGear’s due date calculator is a very accurate calculator available online as of this publication in August 2019. You can, therefore, count on our tool as the most accurate due date calculator available.
Due Date Calculator for Twins
The due date calculator for twins has a minor adjustment compared to regular due date calculators for a single baby. The average pregnancy term for twins is around 38 weeks which is 2 weeks less than the average 40-weeks term for a singletons pregnancy.
If you have twins, you can calculate the due date of your twins using the calculator above and subtracting 14 days from the estimated delivery date.
Due Date Calculator Twins = ( First Day of Last Menstrual Period + 273 Days )
Due Date Calculator for twins IVF
The due date calculator twins for IVF baby follows the same formula indicated below:
Due Date Calculator Twins IVF = (Date of Fertilization + 252 Days)
The four methods above show you how to calculate your due date. As suggested earlier, you can use the tool we’ve prepared for you here at 10BabyGear or you can proceed to try out other tools available online. If you don’t want to use any of the tools, you can develop your own due date calculator excel spreadsheet that will essentially use the basic functions of excel to add up the days and arrive at your estimated due date.
Due Date Calculators Available Online
There are several tools available as of August 2019 and below are the main ones that we reviewed:
Due date calculator the Bump
Due date pregnancy calculator by BabyCenter (also has reverse due date calculator by BabyCenter)
Due date calculator WhattoExpect
Any of the above due date calculators are used by doctors and gynecologists across the US, UK, Europe and beyond.
Due date calculator don’t know last period
If you don’t remember the first day of your last menstrual period(LMP), you can use any day of the week as a variable in the due date calculator above. The due date result you’ll get will have a variation of 7 days and we advise that you go for a reliable estimation by a doctor who can use the ultrasound method to determine the gestation age and the estimated due date without knowing your last period date. If there is no period or the LMP is unknown the ultrasound method is your best chance and we’ve had accurate results with ultrasound when the last period is unknown or when someone missed the period.
Due Date Calculator for Triplets
The average gestation period for triplets is 32 to 35 weeks compared to 38 for twins and 40 for singletons. You should, therefore, plan accordingly to expect your twins earlier than normal, about 5 to 8 weeks earlier.
Frequently Asked Questions on Due Date Calculators
Are due date calculators accurate
We found that online due date calculators are only accurate 20% of the time and external studies have determined that they are accurate 5% of the times. The variation in the actual delivery date may, however, vary slightly by a few days and maybe the correct term that should be used is due date estimators.

What is IVF Due Date?
IVF due dates aren’t determined by your last period, the date of conception, or even the egg retrieval day. They are determined by embryo transfer day and the age of the embryo at the time of the transfer. With IVF, the due date is determined by the date that the embryo implants in the uterus.
From the first week to the last week of your pregnancy, the baby goes through tremendous growth, essentially converting from an embryo to a living being. To keep tabs on your baby’s growth and health, 10BabyGear has put together this article to assist parents looking to understand what to expects about a baby and about the baby’s heartbeat over the pregnancy term.
Part of week 5 and 6, a fetal heartbeat may be detected by vaginal ultrasound. Fetal doppler or home doptone may not be able to detect the heartbeat fully at this week. A lump of 2 to 4mm in length may not be producing sound waves that are detectable by home dopplers. The beats per minute at 6 weeks should be around 90 beats per minute.

Here is another video by Kayce Jones showing her ultrasound sonogram at 6 weeks and 4 days:
Baby Heartbeat at 6 weeks sound:
In the video below, you’ll hear the sound of the baby heartbeat at 6 weeks. To hear the heartbeat sound, you can skip to 1:44
No Sound of Baby Heartbeat at 6 Weeks. Should You Worry?
If you do not hear the baby’s heartbeat at 6 weeks, should you worry? In the video below, Dr. Teena Thomas from Doctor’s Circle answers this question:
Before we go into specific pregnancy weeks before and after 6 weeks, below is a helpful video by the British Heart Foundation explaining when you can start hearing the first heartbeat:
Week 1 and 2: Gestation
This is considered the gestation weeks and the period when the sperm penetrates into the egg with the sole purpose of fertilizing it. It takes a number of days for the sperm to travel in the fallopian tube and actually reach the egg.
Week 3, 4 and 5: Development
In week 3 and 4, the endometrium lining thickens and this is in preparation of the baby’s home over the next several weeks. Ultrasound may not be able to deduct any growth or any living being but transvaginal ultrasounds may detect gestational sac.
Below is a video that summarizes the development of the baby between week 1 and four:
On week 7, a heartbeat can now be detected and it may range from 90 to 110 beats per minute. At this stage, you the chances of pregnancy success goes up to almost 90%.
From week 7 henceforth, you should be able to hear your baby’s heartbeat using a home fetal doppler or using ultrasound in the hospital. You can read more about the different fetal dopplers available and how you can safely use it to listen to your baby’s heartbeat at home.
You should note that from week 12 you won’t have to struggle as you try to hear the baby’s heartbeat as the baby’s heartbeat would have developed and the home doptone will be able to capture every beat.
