Quick update!
I started this post about 2 weeks ago when I was feeling very sad having just found out I was having a boy when I thought (for no good reason really) and wanted (really, because of the clothes and the idea of being best friends like my mum and I are) a girl!
Anyway, I think everyone's answers have been so helpful and inspiring. It's so wierd, I felt I was totally alone and a total freak for feeling negative about having a boy and it was amazing to discover that there are other people out there that feel/have felt the same way.
Two weeks on, and I feel completely differently about things. I still feel a sense of disbelief that it is a boy, but I feel excited about it too. I'm sure I would have felt nothing but happiness had it been a girl, but pregnancy is up and down anyway, and so far emotionally I've had a really easy time. So a blip that lasts less than two weeks doesn't seem like the end of the world!
Worst thing of all - on my inlaws side, the sentence 'its a boy, but she wanted a girl' has now become a kind of fact. I felt as though unless I did something the words 'she wished he was a girl' would end up on my bloody tombstone!
Anyway, yesterday, out of a surge of protectiveness for my little boy I phoned them and said enough if enough, and my reaction (which should have been private anyway but my other half has a big mouth) must never be talked about again. I explained that I had expected a girl and had experienced an emotional reaction to news of a boy, but that I am pregnant and that can happen. And told them that I have no concerns now about having a boy (not strictly true but mostly true and getting truer by the day) and that I never want to hear another word on how I wanted a girl.
My MIL in particular has been driving me crazy by saying things (in a quasi-soothing voice) like 'next time, next time it will be a girl' so I poitned out that this is my first baby and their first grandchild and I will absolutely not have him wished away in favour of thinking the next one might be a girl.
They were both quite surprised at me telling them off like that, but you know, it has to be done! All I could think was this is my little boy, he's coming, he's a real person (imagine if they end up telling him 'she wanted a girl') and I will not have him effecitvely slated for something that is a) not his fault and b) when he hasn't even been born yet!!! (I think this is known as maternal instinct!?)
My other half - althiough slightly mortified I told off his parents - is pleased that I am now defending the baby and feeling postive about it. There is no doubt that had it been a girl, I would not have had this emotional blip, but these things do pass and I already feel that I love my son and most importantly he is my baby and I am lucky he is coming at all. And nothing has made me shift my opinion towards boys than reading all these posts on Mumsnet.
So thanks everyone. And here's to little boys!!!!
