Anyone in the baby mood?

Is there anyone who is really wanting a baby,but you realize you should wait?! My SO and I have been talking having a baby alot (he's like rubbing my belly as though there's a baby in there) and it's making me want one badly he's 20 and I'm nearly 18. We have discussed how we would make it work and he said would take to give the baby and I a good life. He currently works a full time job and Is opening up his own business.
