Heavy Infant Snowsuits in Car Seats: Risks & Safer Alternatives

As winter approaches, many parents reach for thick snowsuits to keep their babies cozy and warm. While this seems like the best way to protect your little one from the cold, heavy snowsuits, and car seats are a dangerous mix. Here’s why heavy outerwear poses a risk and how you can keep your baby safe and warm in the car without compromising their protection.

Why Heavy Snowsuits Are Unsafe in Car Seats

Snowsuits and bulky jackets create a dangerous gap between your baby and the car seat straps, even if they feel snug when you buckle them in. Here’s how this can impact car seat safety:

  • False Sense of Tightness: Thick clothing compresses under impact, creating extra space between the child and the harness. In a collision, the compressed padding could cause the baby to slip or move excessively, increasing the risk of injury.

  • Improper Harness Fit: Heavy snowsuits make it difficult to position car seat harnesses correctly against the body. This leads to a less secure hold, which can be hazardous during sudden stops or crashes.

  • Overheating Risks: Heavy snowsuits in a heated car can lead to overheating, which is dangerous for babies who are more sensitive to temperature fluctuations.

How to Keep Babies Warm Safely in Car Seats

  1. Dress in Layers: Use thin layers that trap heat close to the body. Footed PJs, or long-sleeved onesies and cozy pants can help keep your baby warm without compromising harness safety.

  2. Use a Blanket After Buckling: Buckle your baby in the car seat without heavy outerwear, then drape a blanket over them for warmth. Consider using a car seat cover designed for safety, which fits over the seat rather than between the baby and the harness.

  3. Opt for a Car Seat Cover: For example, the JJ Cole Car Seat Cover. It's specifically designed to keep babies warm in cold weather without interfering with the car seat’s safety harness. The JJ Cole cover is like a fitted "shower cap" that goes around the edges of the car seat, so nothing is placed between the baby and the car seat straps. It’s made with a soft fleece inner lining for warmth and a weather-resistant outer layer to block wind and cold air.

Another popular choice is the Skip Hop Stroll & Go Car Seat Cover which features an elasticized bottom that easily fits around most infant car seats. It includes a soft, cozy interior with a flap you can zip open to check on your baby or adjust the temperature as needed.

Both of these covers provide warmth and protection in winter without affecting the harness fit, making them safe options for parents looking to keep their babies cozy in colder months.

4. Pre-Warm the Car: Start your car a few minutes early to create a cozy environment for your baby before they get inside, so they won’t need heavy clothing to stay warm. If you use an infant bucket style car seat, you can bring the car seat inside to keep it warm. 

Test Your Baby’s Car Seat Fit for Winter

A good rule of thumb to test if your baby’s clothing is car seat-safe is to buckle them in with and without the coat. If there’s any looseness when the jacket or snowsuit is removed, it’s too thick to use in the car seat.

Safety First:


Winter weather shouldn’t compromise your baby's safety on the road. Avoid heavy snowsuits in car seats, dress your infant in secure, warm layers, and make sure their harness is always tight enough to protect them.

By understanding the risks and knowing safer alternatives, you can protect your baby from both the cold and potential car seat injuries this winter. Stay safe and warm with these tips from NEOwell!
