Shamelessly posting for traffic...trying to buy my ds school trousers. I thought he was a normal sized 4 year old (summer born baby) but age 4 trousers are huge. So I buy age 3 and put them on the smallest setting on the elasticated waist - still too big. What do I do, I can't buy age 2 school trousers!! Oh and I can't sew either. Anyone else have this problem?
