I have got two sons, now aged 19 and 17. When I was expecting no1, I was totally convinced that he was a boy, didn't look at girls clothes, consider girls names, nothing. Luckily, I was right! (only lucky in that the baby had only blue etc and James is a crap girls name!)
With no2, I didn't have a clue about the sex, had a very different kind of pregnancy, everyone kept saying 'ohh, must be a girl this time' I didn't actually want a girl, I quite liked the idea of 2 boys close together (agewise)
My boys are so different, the eldest is stroppy, hormonal and I swear he has PMT. I find him incredibly hard work, he won't discuss his feelings, thoughts, hopes, dreams or fears.
The youngest is very 'in touch' with his feelings, he will come clothes-shopping with me, will watch girly films with me. He tells me that he loves me everyday, asks me if I need anything. Notices when I am miserable and gives me a cuddle. He also plays rugby, is one of the most 'macho' kind of boys I know.
I think that what I am trying to say is that all children are themselves, it isn't anything to do with their sex, girls can be into rough and tumble, football and cars. Boys can be into ballet, soppy stuff and pink.
You should always love them for the people they are, not put things down to them being boys or girls.
