DS3 came home with fluffy homework about being yourself, mostly banal sentences to complete such as "I'm good at..." "I enjoy..." "I find ... difficult" "I'd like to try..." "I'd like to be" and favourite book, film, colour, food etc.
One of the questions though was "I like being a girl/ boy because..."
DS wrote "I don't know"
Is it a weird question? It can only be answered with a gender stereotype can't it? Maybe a girl could be encouraged to write "girls can do anything" - for a boy to write that seems to be a bit, well, cocky 
sorry...
With this child alone among my children I've had to spend time reassuring that boys can do anything, just like girls can, after mini emotional crises about liking colours, TV programmes, toys and books which his classmates tell him are for girls... He's also growing his hair (allowed at his school) He doesn't have any identity issues, he knows he's a boy and is perfectly normal, likes things stereotypically associated with both girls and boys.
He's only 8, he's just a child, obviously children need to know whether they're girls or boys and what adult women can do (have babies, breastfeed) which men can't, and gradually understand how puberty affects their biological sex and what to expect. Beyond that though - is there anything to "like" (or dislike) about being either a boy or a girl at 8?
Should he write "because I'll never have to have periods or an emergency caesarean section"...
Is it not a weird question?
