Child Care While On Active Duty In The Air Force?

I'm going in the Air Force AD soon and just recently found out my wife is 8 weeks pregnant. She is throwing a hissy fit saying the child care needs to be 50/50 once I'm in the Air Force, I don't agree. She is just going to be at home with the child and doing online college courses, I will be working full time; doing online college courses; and helping with the child. Is it wrong of me to think that the baby and house hold chores will be more along the lines of 70/30 or 75/25? I just think that it is unreasonable to say that I have to work full time while she doesn't and yet I have to do as much towards changing diapers/cleaning as her. I love the fact I'm going to be a father, though it came a little too early, and I want to help take care of my child I just think I should have a little less responsibility for care since I also have to work. I'm not trying to be ist, if my wife wanted to join up, she cant though since shes knocked up, I would stay at home and do 90% of the child care. I'm not trying to start anything bad with this question I just would like to know.
