help! why do I want another?!

I just had my son two months ago via c section and me and my hubby are already baby crazy! I have the paraguard IUD so it's not just like I can stop taking a pill. I just don't understand, we originally were gunna wait 3-5 years and now we don't even wanna wait one. My son is an amazingly easy baby and we're not financially struggling. My biggest fear is having a repeat c section. Wtf is wrong with me?! How can I stop this urge???
