An infant seat is outgrown when the baby reaches the top weight listed on the seat's label. For most models this is around 20-22 pounds.
- Do not exceed the weight limit specified on the seat's label.
- Your baby has outgrown the seat when there is no longer at least one inch of padding and seat back above the baby's head.
- Straps should be at or below the shoulders when riding rear-facing. Read and follow the manufacturer's instructions that come with the seat.
- If the baby is tall but weighs less than 20 pounds or is less than one year of age, move the baby into a convertible seat that will allow the baby to remain rear-facing until at least the first birthday AND at least 20 pounds. Read the manufacturer's instructions and check the label to assure that the seat you want to use is approved for rear-facing use to at least 30 pounds. Once the child is at least one year of age AND at least 20 pounds you may (but are not required to) turn the child to the forward-facing direction. Read and follow the manufacturer's instructions for proper installation and use. Remember that riding rear-facing offers the best protection for your baby's neck and spine.
