Careful, you might jinx yourself and find yourself preggo again. That happened to a friend of mine. Course, you might want more kids - my friend didn't and got a surprise.
We're just starting the process now, putting the little man on his potty when he wakes in the morning and from his nap and rewarding him when he goes. A couple times he's said, "potty" and tugged at his pants so I rushed him to the bathroom for him to sit there and do nothing except look cute. Oh is this gonna be fun!
I remember that day. It felt so weird going to the store without a diaper bag. I had carried one for 7 years straight. As soon as my oldest got potty trained, I had my second son.
