DD is about 4.5 and is very tall for her age (always in the high 90th percentile for height, and her weight is proportionate to go along with it- I don't remember the exact numbers right now and she's in bed so I can't measure her). She's currently in a Radian in one car and a Britax Frontier in the other car. I'd like to move her into some sort of booster to give the Radian to her little brother, but, of course, I want her to still be safe.
Can you recommend a booster for a 4.5 year old?
Thanks for your help!
Oops- forgot to add the poll. Please feel free to chime in with what kind of car seat your preschooler is in, though. I'd love to know if I'm jumping the gun on the booster, or if there's some sort of combination convertible-booster that she could do the buckles on herself.
