Thick coats and child seats.

Parents everywhere bring out their babies’ winter coats or snowsuits to keep baby warm during travel. However, thick winter coats or snowsuits can compromise your child’s car seat safety.

In order for a baby car seat or toddler booster seat to function properly, the straps need to remain tight against the child’s chest.

Experience Winter with your child

Walk outside. Let your toddler experience firsthand the feelings and sights of winter. Explain how it is cold outside. Emphasize the need for coats, hats, mittens and boots when outside.

If there is snow on the ground, touch it and walk in it. Let your toddler feel how snow is different from the ground. Don’t be surprised if your toddler doesn’t like it and wants to go inside.
