I leave home for work at 6.30am; DH, who works from home, gets the kids up later and takes DD (3) to nursery and her brothers to school. I get lunches and clothes ready the night before and plait DD's shoulder-length, curlyish hair to keep it from tangling while she sleeps. He gives them breakfast, gets them dressed and out the door. But he NEVER does DD's hair. She spends all day with her sweaty unbrushed hair in a half-undone plait, flapping round her face and making her even hotter (we live in a hot country and it's min 35° every day.) I've asked him lots of times to deal with it and shown him easy ways to tie/clip her hair up that take about 3 seconds to do, but he just won't. He says it takes too long in the mornings and we should just cut it all off short until she's old enough to do it herself. This is just him being a lazy numpty in my view; besides, she has pretty hair and I don't want it cut off. Who is BU?
