a question of gender

What do people call the baby besides "it" when you don't know (and aren't going to find out) the sex? I'm having trouble imagining this androgynous being. If I talk to Josh about the baby (it?!) I find myself saying "I hope he wants to skateboard! Or she. She can skateboard."  How can I start pushing all my hopes and dreams on this unborn child if I don't know it's gender?!
