Sometimes I think it is easy to imagine what it might be like to have what you don't..or aleast the possibility..I have 3 girls soon to be 4 and 1 boy , my man is a man..but he loves his mummy, the girls are all about daddy??? My oldest is 17 and she has given me a run for my money, I sometimes wonder if it will all work out and we will be close??
My DH comes from a family of boys and they all would have done anything for there mum, she has since passed, but on my DH insistence we visited every fortnight overnight, I did'nt mind, I was actually very proud that he treated his mum in that way.
Before you embark on another baby it might help to get some professional help...and work through how you are feeling...its certainly not wrong...but you also don't want your disappointemnt to grow out of control.
Good luck.
