I didn't know where to put this but it's kinda sn related, My Dd3 who has a possible asd hates buttons [except the television ones lol.] I have been findin it really hard to get proper trousers, not leggings without buttons. We had some boys jeans from H and M last year and I sewed some "hello kitty" badges on them but now they are too small.
Anyway I found some really nice combat ones and jeans in Vertbaudet today, with a nice soft pull up waist and roll up legs. Nice patterns too. Just thought I would let you all know because I know Dd3 is not the only child who doesn't do buttons. They are not cheap but hey.
