Trust me, you will love your boy.
I split with my fiance during my pregnancy, so I sort of hoped my baby would be a girl - it just seemed an easier option for a single mother. I'd also chosen a girl's name when I was a teenager, it's always been Isobel. I had no idea what I'd call a boy. I couldn't imagine how I'd cope with a boy either.
Anyway, when he was born, he was a boy - Matthew. I loved him from the second I saw him. His sex was irrelevant. He was my baby, he needed me, and I loved him with an overwhelming force that I'd never anticipated.
He's now nearly 3. He's so cuddley, really affectionate, far more so than his female contemporaries. I love the fact that he gets excited when a tractor drives past, that his first word was "tractor", that his wardrobe isn't a sea of pink. He isn't aggressive, he doesn't hit, he's not boistrous and loud - he's just a lovely little child who sometimes stops mid-play and says "Mummy I've got a good idea, let's have a cuddle".
Boys are great. And I can say, hand on heart, that if I'm lucky enough to get pregnant again I'd be completely happy with another boy, despite my earlier reservations.
