Oh boy do I know what you are going through.
I had a boy the first time (he's now 17!) and I wanted a girls o badly the second time because I thought I wasn't going to be able to have any more....I had toxemia with both of them.
When I found out it was another boy, I literally cried....in the delivery room. We didn't know before he was born what we were having.
I didn't get to go to my 6 wk check up, and didn't get to the doctor till he was 10 weeks old. Well, I had a very difficult time bonding with him. It felt like he was my nephew or something... I loved him, but didn't feel like he was "mine".
At my check up, I talked to the doctor about it, and told him i couldn't have any more and he said "Why not". When I said, I thought he'd tell me not to because of the toxemia and c-sections, he said there was no reason I couldn't have anymore.....
After that, I felt better and I started bonding with my son.....he is now 16 years old.
I did eventually have a daughter, who is now 10. Yes, I really wanted a daughter with her too, my husband wanted a boy, but he adopted my two sons a few years later and he is very happy with all of them.
My point is, don't sell yourself short. Ok, so you don't have a lot of money, no one does.I've always been told that if you waited to have kids till you could afford it, you'd be a grandparent.LOL
Well, I am becoming a grandparent in May, and we still can't afford it! Not only do we have our 5 kids, my son's girlfriend is living with us (because of the pregnancy and problems at home.) We will also be supporting the new baby when it comes.
I am a stay at home mom and can not work, so my husband is the only income and he is able to cover everything..... there are days we feel like we'll go under, but the bills get paid.
give yourself some time. Don't convince yourself that this is your last one.... yet. You may decide later that you are done. But don't do it until you have to. Know that the option is there if you want it.
You will be able to relax and you will love this boy as much as the first one.
Who knows what the future brings? You may get a surprise someday and get that girl you always wanted..... and even if you don't....remember, when your boys grow up, you'll get 2 daughters when they each get married..... you'll still get your girls.
