In a policy statement published in Pediatrics, the American Academy of Pediatrics now advises parents to keep toddlers in rear-facing car seats until age two, or until they exceed the height or weight limit for the car seat, which can be found on the back of the seat.
In the case of car seats, there are convertible models available that last from birth to four years. If suitable for your car, a convertible model will save you the expense of buying a new car seat each time your baby outgrows the old one. It's best not to carry your newborn baby around in a sling, car seat, or pushchair that doesn't lie flat for long periods of time.
