@churchboi Er, sorry for that. I meant that they only need to be rear facing for that long, which isn't in line with what I've heard best practices to be. There are also laws about how long they need to be in a car seat an booster for.
@churchboi Eh, where I live (Quebec, Canada) it's 1 yo and 22 lbs legally, but they recommend leaving it rear facing as long as possible. (I waited past 2 years, but I know not everyone does.)
