I just discovered that the lap belt can fit too low. I've always been so concerned about keeping it off the belly, that I'm embarrassed to say I did not realize this could be an issue. My DD's booster lap belt does fit quite low, something I thought was a good thing, so how do I know if it's too low? i dread even asking this question because she loves her booster and will freak if she can't stay in it, yet her safety has to be my priority. After all, while many others are taking theirs kids out prematurely, the whole reason I'm keeping her boostered is for proper fit.
