DS (15) has decided he isn't wearing 'kids' clothes anymore. What that means is nothing size 15-16 as opposed to adults size small. All of his most recent clothes are men's small size but about half his clothes are boys 15-16 and perfectly good and he is saying he will not wear them and has removed them all from his wardrobe! I've told him - to look at them you can't tell the difference between the two unless you look at the tag and who's going to do that ?! But he is adamant he can not wear anything 'for kids' any longer! This includes all of his underwear - I buy all underwear for DS 12 and 15 in the M&S or Next boys section. So he needs loads of new stuff basically. I get it that he feels like he wants to be a man but this seems all quite unnecessary and I'm trying not to get annoyed. Do I give him money to get a load of new stuff ? AIBU? (OR IS MY DS?)
