I'm just getting tuned in to the recommendations for car seat safety (beyond what is the law) and y'all just helped me pick out some new seats for my younger kids which should be arriving tomorrow! My just turning 11yo has been riding with just a lap/shoulder belt for a few years. I think a lot of 11yos would be fine, but he is only 62lbs, and 53 inches, AND, our 12-pass Chevy Express has no headrests, just bench seating. After reading a lot on this board, I'm guessing that he should technically be in a high back booster! I sort of hinted around that he may be getting a new seat for the van, too, and he just about laughed me out of the house! I don't have a problem forcing this if I decide it is truly a lot safer for him, but what would y'all do? Looking for opinions!
