My 6yo is tall and skinny: 48 inches tall, 39 pounds, 17 inches shoulder height when sitting. In our car she is in a Radian in booster mode, but I need a new seat for her for the grandparents' car - IMMEDIATELY, as in TODAY, because DH and I are going a trip for three days and it just occurred to me that the grandparents' current seats are not safe (they are outgrown since the last time). DH doesn't want to put our seats in their car - long story.
Anyway, I'm not sure what I need for DD6. She seems too small for a backless based on her weight, but she is so tall, and I don't know if I need to spend the extra money on a highback. I will do what I need to do to keep her safe, though. DH's parents have a 1997 Suburban. My kids sit three across in the middle row, with the other seat being a convertible in FF mode for DD3 (can't remember which one - I think it's Evenflo).
ETA: My 8yo will have a backless booster in the grandparents' car.
