3 months PP and NEED another baby!

I just had my baby boy 3 months ago. I seriously LOVE being a mom so much. Is it crazy of me to already want to start trying for another? Any other women feel this way so soon after having their baby? My husband is okay with getting pregnant again. We want a large family (7+ children). UPDATE: I gave birth July 31 and had a normal delivery. I had a period a month after giving birth, and am very regular. I know exactly when I ovulate. We are doing NFP, but not strictly because I don't care if I get pregnant again.
