In colder weather, parents typically dress their children in winter coats. But it’s important to know that heavy coats can interfere with the proper harness fit on a child in a car seat. When your child will be secured in a car seat, pick thin, warm layers, and place blankets or coats around your child after the harness is snug and secure for extra warmth.
Also, make sure car seats and booster seats are properly installed and that any children
riding with you are in the right seat for their ages and sizes. See NHTSA’s child passenger safety recommendations to find the right seat for your child’s age and size. You can visit NHTSA’s Child Car Seat Inspection Station Locator to find a free car seat inspection site near you, or to get information on virtual inspections.
