Putting your child in a car seat bundled up in their winter coat is a mistake any parent can make in the winter.
When a child is wearing a winter coat, it may feel like they are strapped snugly into a car seat when the straps are actually dangerously loose, Sue Auriemma from Kids and Cars told NBC's "Today" show.
At an official crash test lab in Michigan, a child dummy that appeared to be securely strapped into a car seat came hurtling out of it in a simulated 30-mph crash.
Experts say to strap your child securely in their car seat without their coat on. Put the coat or a blanket over the child to keep them warm, Auriemma said.

The advice applies to adults, too: Experts say they shouldn't wear their winter coats when they're behind the wheel or riding in a car.
