A child can be either too heavy, too tall, or bothâbut all of this depends on the specifcations of the car seat. Each car seat has its own height and weight limits for rear-facing children. Most convertible seats allow children to sit rear-facing up to 35, 40 or 50 pounds. The height limit for most rear-facing car seats is that there must be at least 1 inch of room between the top of the childâs head and the top of the car seat.
These seats typically have higher height and weight limits for the rear-facing position, allowing you to keep your child rear-facing longer. If a baby under 1 year old grows too tall or too heavy for an infant car seat, a car seat with a higher rear-facing height and weight limit is strongly recommended. Place the car seat base in the back seat of your vehicle. 2  In a crash, the back seat is the safest place to be, and rear-facing car seats provide extra protection for your childâs head, neck and spine. 3  Locate the lower anchors in your vehicle.
