I swear my 4yo son always has half his butt hanging out of his pants. He doesn’t have much there to hold anything up, but I feel like I should be able to find underwear to cover his butt crack even if his pants sag. So far we’ve tried Cat & Jack, Fruit of the Loom, Hanes - has anyone successfully solved this problem, either with another brand or other tricks (sizing up)?
