Winter coat while in car seat?!!

Britny

Do you allow your child to wear a winter coat while in their car seat? I was just reading about “When a child is wearing a thick winter coat, it may feel like they’re snug in their car seat, but in reality, the straps are actually very loose. It may not seem like a few inches of fabric and filler would make a difference, but the consequences could be fatal. Official crash tests confirm this, as a child dummy that appeared to be securely strapped into a car seat flew out of it in a simulated 30-mph crash”.... I never thought of this until today. I’ve been letting my son wear a winter coat in his car seat but now I’m wondering if I should start taking it off. Just curious what other mommas think.
