4. Reclining your child at the wrong angle

If your child's car seat faces the rear of the car, follow the seat maker's instructions to recline the seat. Do this so your child's head doesn't flop forward. Babies must ride semi-reclined to keep their airways open. Many seats include parts that let you change how much the seat reclines. Many also include a device that helps you find the correct angle to recline the seat at. As your child grows, you might need to change the angle. Check the seat maker's instructions for details.
