Which are safer for a kid that fits into either of them? over 30 lb and over 3 ft tall.
I need to get my DD a car seat and am not sure if I should give her DS' convertible and get him a booster or buy her a new convertible.
I don't mind spending the $$ whichever way we go, I just want him in the safest possible seat.
ETA: I'm talking about the typical convertible vs the "Combination Harness to Booster" type.
