DS is 2.2 and (rather surprisingly) potty trained. Now that he's not in nappies, it turns out he has tiny wee hips and bottom, and his trousers, which fitted fine over nappies, keep falling down. I have a few with adjustable waists, but not many, and I don't want to buy a whole new load of trousers. Is there such a thing as braces for wee ones? Should I go the whole hog and buy him a flat cap?
