SO I suggested a Britax Frontier to a friend for his almost 4 yr old. The child is big, in every way. I believe he is about 60lbs, tall and wide. They say he doesn't fit in the seat, that his logs go over the cup holders and they don't want to buy a seat that won't last. I don't really understand since my kid was in it until she was 9, 100lbs and wider than he is. So now I need more suggestions, because this friend really wants to just use a booster, which he would have the same problem, width wise. Only thing I could think of is a ride safer vest, I don't think even that would work.
