Carseat Crankypants
My daughter is 10y9m, 4'11.5", and 95ish#. I very recently took her out of her boosters, because in our vehicles, the belt fit is much worse with boosters than without. If the belts fit properly, she would still be boostered, because the booster arms act as artificial hips and help hold the seatbelt down, which is a big plus for prepubescent kids (hipbones harden and sharpen during puberty).
