The short answer is - yes - winter coats are dangerous in the car seat.
I know - I know - it seems like there's a lot of hype around puffy coat dangers especially when viral videos show children being thrown from car seats with obviously improperly tightened/loose straps leaving you thinking well if the straps were just tighter.....
The Unvarnished Real Deal
It is impossible to tighten the straps correctly with a winter coat on.
In a car crash the coat not only compresses creating space between your child and the harness but the force of the crash can stretch the harness up to 7%! Even if your child is not thrown entirely from the car seat all the stretching and the space left from compression will pitch your child too far forward. Studies show that as the distance forward increases the risk of critical injury also increases. In fact as little as 6 millimeters of forward movement can be the difference between walking away from a crash and sustaining critical injuries.
The Safest Solution
Tight harnesses directly on the chest and shoulders with a properly secured top tether decreases forward movement which dramatically reduces risk of critical injury and death. Which means - in short - take the puffy coats off parents. The risk in a crash is just not worth skipping a step.
Pressed for time or don't want to deal with the struggle?
Use a Buckle Me Baby Coat - which is crash tested and designed for easy winter car seat safety, use a blanket, or use a light fleece jacket.
Parents who have discovered Buckle Me Baby Coats say:

I got the pink plaid and it’s so soft and cute. The only, I wish it was thicker for those colder days. I will say, I used the blanket today, along with another small blanket, and it just proved how well it was designed. My daughter loves to kick the blanket off of her feet, and she did just that with the extra blanket. The Velcro strap on this blanket ensured the blanket wasn’t going anywhere.

Better than expected
I had the lightest version which was nice for all year, but with colder days coming I ordered this version and its better than expected. Definitely thick but not too heavy, well-made and baby loves it!

Baby size snuggle sack!
This is absolutely perfectly practical for a newborn in a car seat. That’s going to be born this winter. It’s very soft and lightweight and will be easy to put on and off.

So soft!
I purchased the pink for my new granddaughter for Christmas. We live in AZ so it doesn’t really get that cold. Being a Nana of 6, I hate taking coats on and off at the car seat. I’m really happy that I found the buckle me coat.

Love it
Warm enough for Chicago winters in and out of the car (we use a different coat if we're out for a long time). Totally worth it to not have to take it on and off when running errands or going to school! This is our 3rd winter with the same model.

Best pjs EVER!
I have tried bamboo pajamas from SO many different brands, but none are as good as the BMBC pjs. They're actually buttery soft, hold up extremely well in the wash, and my baby can wear them for so long due to the extendable arms/legs and stretchy material. My 14 month old is 95th percentile for height and weight and the 6/9 month BMBC pjs still fit him!!! Cannot recommend this company enough. And Dahlia, the owner, is so sweet and responsive.
