How can I tell when my child has outgrown his child safety seat?
Children should ride in safety seats with a complete harness system as long as possible. Most seats with a harness fit children up to 40 pounds, but a tall, thin child may outgrow a seat with a harnass before 40 pounds.
If your child's shoulders are above the harnass or your child's ears are above the top of the seat, try a combination child seat/booster with higher strap slots. The harness in a combination seat may be used up to 40 pounds; then it is removed so the seat can be used as a belt-positioning booster.
