DS1 (3.9) is tiny - he's just moved up into size 18-24 month clothes. Problem is he has no waist or bottom so his trousers always fall down - to make it worse trousers for 18-24 month olds are designed to fit over bulky nappies while he wears pants.
Does anyone know any shops where sizes come up small around the waist? Poor DS spends his life pulling his trousers up! Oh and I can't sew so please don't suggest tucks or anything!
