Oh boy, I mean no boy!

Found out we're having our 3rd baby girl. I'm not handling it as well as husband mostly because I only wanted 3 kids and I really wanted him to have a son. Now husband is joking about 4 kids and paying$$ to have a boy!!! I just don't know if I can't handle 4 kids or 3 while pregnant with a fourth. So many mixed emotions. I hate the idea of having a fourth before the third is born.
