I wanted a boy - not for any 'gender preference' but precisely because of the stereotyping that goes on around girls. The expectation that you will be 'girly' and like pink, frills, nail varnish etc. I've never been girly so would feel out of my depth with it & would be irritated by people pushing a girly agenda onto my child.
Dc1 is a boy & I'm now pregnant with dc2. DH would like a girl; I'd like a boy. I'll love them equally whoever they are, but would be more nervous about doing a good job raising a girl.
Incidentally, DS (2) loves making me cups of tea with his toy tea set, reading books, colouring - he also loves trains, tractors and creepy crawlies. And his communication is great for his age. Silly Beverley.
