✓ Store infant seats inside the house when not in use
Keeping the seat at room temperature will reduce the loss of the child's body heat in the car.
✓ Get an early start
Plan extra time when taking your little one out in the winter. You may have to remove a coat or adjust the car seat straps. It is also prudent to plan to take extra time driving in wintry conditions.
✓ Dress your child in thin layers
Especially for longer car rides, start with close-fitting layers on the bottom, like tights, leggings, or long-sleeved bodysuits. Then add pants and a warmer top, like a sweater or thermal-knit shirt.
Remember, as a general rule of thumb, infants should wear one more layer than adults. If you have a coat on, your infant will probably need a coat and blanket.
Remove the coat and blanket inside the car before putting your child in the car seat
✓ Hats, mittens, and socks
Substantial amounts of heat are lost from the head, hands, and feet. Simple coverings can help keep your baby warm without interfering with car seat straps.
✓ Tighten car seat straps
Multiple layers may make it difficult to tighten the harness enough. If you can pinch the straps of the car seat harness, then it needs to be tightened to fit snugly against your child's chest.
✓ Use a coat or blanket over the straps
A blanket over the top of the harness straps or placing your child's winter coat on backwards (over the buckled harness straps) after he or she is buckled up can keep your little one warm and safe.
Some parents prefer products such as poncho-style coats or jackets that zip down the sides so the back can flip forward over the harness. Layers over the car seat straps should be easily removable so your baby does not get too hot after the car warms up.
X Do not use car seat covers
Nothing bulky should ever go underneath your child's body or between her body and the harness straps.
Be sure to leave your baby's face uncovered to avoid trapped air and suffocation.
X Never use sleeping bag inserts or other stroller accessories
Remember, if the item did not come with the car seat, it has not been crash tested and may interfere with the protection provided in a crash.
