Wow that is CRAZY that you know its a boy, and your DH doesn't!!! I am the worst secret keeper, that would eat me up inside
We have two girls and this is our last baby, so he didn't want to find out early that it was another girl and be disappointed. He figures at the time of the birth he'll just be so happy, that it wouldn't matter. For me, however, getting my tubes tied (which I definitely want regardless of gender), I had to deal with the fact that if it was another girl, I wouldn't have a boy. I felt like, for me, that was an emotion I needed to deal with and now while I just had a baby, and laying on the operating table.
So far so good, and I don't think he knows. Fingers crossed I can make it another 13 days. :-)
