17 with baby fever!

Kassidi
Is 17 way to young to have baby fever? I'm almost 18 and don't plan on having a baby soon but me and my boyfriend both have crazy baby fever. We babysit my cousin Addison who's about a year and a half and we always make a great team. We can Even handle her crying together. We're actually really financially stable, with a lot of savings, but I'm going out of state for college. He wants a baby and is in college with an apartment but I don't want a baby right now. How do I keep down the baby fever so I don't accidentally suggest having one in the moment?
