Car seat safety: Avoid 9 common mistakes
3. Using the car seat outside of the car
A car seat is designed to protect your child during travel. It's not for use as a general seat or replacement crib in your home. Sitting in a car seat for lengthy periods poses health risks. It can affect your child's ability to breathe, contribute to the development of a flat spot on the back of your baby's head and worsen gastroesophageal reflux disease (GERD) — a chronic digestive disease. In addition, a child can easily be injured by falling out of an improperly used car seat or while sitting in a car seat that falls from a table.
Although it's essential to buckle your child into a car seat during travel, don't let your child sleep or relax in the car seat for long periods of time out of the car.
