How can I tell when my child is ready to use car seat belts without a booster seat?
Your child will be ready for using the car safety restraint system when s/he can sit all the way back in the seat and the knees can bend comfortably over the edge of the seat. The belt crosses the shoulder between the neck and the arm and the lap belt is low and touches the thighs. Your child must be able to remain seated the whole trip.
