My girl turns 10 this month. She's had a growth spurt and has really filled out and gotten some hips. In December she was 72 pounds and 51" tall. And she's assuredly grown since then. I expect she may add some height next, but for now I think she still needs a booster of sorts. In my car we use a Diono Cambria. The babysitter has an older backless Graco that apparently is now too narrow (between the arm rests). The Diono is getting snug/narrow, too. Can she sit on a cushion for a bit of height to get the shoulder belt properly placed? Or is that dangerous/could the cushion slip from under her in a crash? It seems most backless boosters have arms, and fitting between those arms is the issue. What to do? Thanks!
