Wanting another baby...

I feel nuts. My son is 7 weeks old an I already want another baby. Please don't bash. I know all the health risks to getting pregnant again so soon. I don't actually plan on trying but I don't know why I feel this way. I miss being pregnant so much an seeing everyone pregnant makes the baby fever so much worse. I love my son so much I can't wait for him to have a baby brother or sister(: but I must be nuts right? Then again I know a lot I people who have children back to back an say how amazing it is... Guess I'm just looking for feedback on both sides not just people telling me not to...
