Now that we are about to enter the winter season, most parents are thinking about ways to help their children warm in the car seat without compromising on safety. Winter coats and snowsuits come in handy during this season, but the American Association of Pediatricians (AAP) warns parents that they are dangerous to use while buckling kids in their car seats. This is because the fluffy padding flattens out from impact during a car crash, leaving lots of slack underneath the harness. The baby can then slip from the loose straps and be thrown out from the seat.

If you want to find out safe ways to keep your child warm in the car seat, here are some tips:

10 Tips to keep baby warm in the car seat

1. Use a blanket

Instead of wearing a fluffy coat, use a large blanket to wrap around your child and then buckle them up. Kids always have that special blanket that they adore, and we are sure if you use it, they will be less likely to be a fuss.

2. Try a fleece coat

If it is freezing cold outside and toasty warm in your car, your baby might overheat. Coats made of fleece are a great option as they do not have lots of padding underneath the harness straps. And when wearing unzipped, they provide an even better fit than a winter coat.

3. Tighten the car seat harness straps 

If you dress your child with multiple layers with the coats, it might make it difficult to get the harness straps tight enough. The harness should be tightened to provide a snug fit against your child’s chest. If you can pinch the harness straps, it is an indication you still need to tighten up some more.

4. Wear coat backward

This is another simple idea that you can use. You buckle your child and then place their winter coat over them backward, while already buckled up. Some parents also opt for coats that zip down the sides so that the back can flip forward over the harness or poncho-style coats.

5. Use thin layers

Layering helps to keep the body warm, and blankets provide a smooth coating to wrap around your baby when you leave the house. It is also easy to remove when your child gets into the car or if the interior temperature rises to prevent overheating.

6. Turn up the heat

When it’s freezing cold, just turn up the heat to make your car warm and comfortable for everyone that is riding.

7. Strike the right balance of layers and your car’s interior temperatures

During cold weather, it is normal to worry if your child is warm enough, which might cause you to overdress, leading to your child. When this happens, your child may end up overheating and becoming uncomfortable. By dressing your child with just enough layers and adjusting your car’s interior temperature, you can keep your child comfortable during car rides.

8. Use a suitable car seat cover

You may choose a seat cover but ensure that it doesn’t have layers under the baby. Remember, nothing bulky should ever be placed between your child’s body and the harness straps. Also, ensure that the baby’s face is not covered by fabric to allow airflow and prevent rebreathing stale air, which can cause suffocation. You should be keen because many retailers sell car seat bundling products that are not safe to use in a car seat.

9. Consider getting a car seat that has features for cold weather

If you live in places where it’s normally cold, you might need to consider buying a car seat with all-weather features to help keep your baby warm and comfortable.

10. Keep an emergency bag in your car

You may want to pack extra blankets and clothing like hats, mittens, and gloves in your car just in case you will ever need them. You never know when a nasty mess might happen or in case your child gets their clothes wet from the chilly weather. With a spare set, you will still be able to keep your child dry, warm, and cozy.

Are car seat blankets safe?

Yes, you can wrap a blanket around your child as a top layer over the harness to provide warmth and block out the wind. And if your baby is using an infant car seat, cocoon-style covers may be a better option.

Can a baby wear a snowsuit in a car seat?

No, you should not buckle your child in their seat while they are in a snowsuit. The fluffy padding of the snowsuit would flatten from the crash force, leaving your child loosely strapped and prone to slipping out of their seat during a crash.

Can a baby wear a blanket in the car seat?

Yes, you can wrap a blanket around your baby and then buckle them in for warmth. Blankets are safe to use underneath the harness because they do not have fluffy padding that may prevent you from tightening the harness straps snuggly around your child to keep her secure in case of a crash.

How to bundle up baby in winter

To dress your baby for warmth during chilly winter days, start with body-hugging clothing on the bottom like tights or leggings or a long-sleeved bodysuit. Then add regular pants and a warm top, like a sweater or thermal-knit shirt. You can also add a fleece jacket over the top. And when it is bitterly cold, long underwear is also a warm and safe layering option.

As a general rule, babies should always be dressed in one extra layer than adults. This means if you have a coat on, your baby will need a coat and blanket. Just remember to remove the extra layers of thick coats and blankets once your child gets inside the car before sitting in their car seat.
