My hubby knows the baby's gender because he didn't want to wait until the Gender reveal/diaper party to find out. I requested that he stay away from pronouns and we just call our baby Z. But he has to be difficult and so we'll be talking and he'll say she is moving so much and then he will turn around and say I'm so glad that he is our last. He sucks I just should have made him wait and let him complain about how stupid it is, I love surprises but not with angst.
