Baby fever?!

So my bf and I have been together 2 years now. I love him so much. Lately i have had the worst baby fever. I do get it occasionally but this time is the worst ive ever had it. I think about us having a baby non stop.... i think about him being a dad and holding our babies. Whenever he spoons me at night and has his hand on my belly i imagine there being a baby inside of it and i also think about us laying in bed and having a little baby in between us. Is this weird!?! I feel like i am crazy for thinking all of this. But i cant help it
