As I age I have less and less baby fever

As I grow up, which I’ll be 22 this year, I seem to have less and less baby fever. Not because I don’t love my husband but because as I grow more independent from my family and since I currently handle my own bills with my husband, when we sit down and talk about bills for the month and what we can handle, it just doesn’t seem like a baby budget fits in there ever. When I first started dating my husband when I was 17, all I could think about was being a mom now that I’m 22 all I can think about is how I’m going to make this month’s bills and how much can I put in my savings this month to knock out our debts. Is this normal and how did you overcome this?
