The correct type of car seat depends on your child's height and weight and not necessarily age.
Read your car seat owner's manual to verify that it was in fact intended for your child, and to see if it's time to upgrade to the next type of seat.
If you're not sure, schedule an inspection free of charge or attend a safety inspection checkpoint (dates will be posted here in the future). Call Sergeant Kaycee Mitre
