Morris, it's totally, totally normal.
I also had really wanted a girl, and for some reason expected a girl, because mostly women in my family had girls. ( I now have four boys so kind of bucked that trend a bit!
Also, ds1 was breech. In the run-up to his birth I had to see the "breech doctor" who helpfully
told me that a lot of breech babies have health problems such as deafness and cleft palate. To this day, I don't really know why he felt he had to say that as although the risks are a bit higher with breech babies, you are still far more likely to have a healthy baby than not and as ds1 looked perfectly healthy on his scans, and is a healthy lad generally, I can't see why he thought he was being helpful.
So ds1 was born, he was a boy, which shocked me, he didn't look like I thought he would although tbh, I doubt if any babies look like their parents think they will, and I was constantly watching out for his alleged health problems. I even hurt the roof of his little mouth with my nail accidentally while looking for the cleft palate
When I took him home, I was exhausted. My sister came to help and I remember crying when she left as I didn't think I could cope. My mum came up later but didn't really get that I had had a CS and that I needed more time to recover than with a natural delivery so wasn't as helpful as she could have been.
My wound was sore, I now think infected, I could barely walk and I remember my Mum sending me out for a walk with my sister because she thought I could do with it
and having to stop to rest several times along the way.
And ds1! I was overwhelmed by the fact that he needed me and only me and needed me so much and so relentlessly and I felt so resentful that he wouldn't let me be for a few minutes. I also felt so guilty that I would have to go back to work and felt I was cheating him becuase he thought I was going to be around forever.
On maternity leave, I used to bring him for walks to the local pharmacy and buy dummies he didn't need just to talk to someone.
It was only 6-8 weeks in that I began to slowly feel that things wouldn't be so bad I brought him in to show him to the girls in work and when they coo-ed over him and said he was so gorgeous and clever and advanced that I felt this love and pride I thought I would feel from the beginning.
He is 14 now and I have to say, I look at him and he's taller than me and so good with his little brothers, he brings me cups of tea when I am MNing and I absolutely adore him!
