Potty training?

MR went pee today, amazing I know. But it was, because instead of his usual diaper wetting he went pee in the potty. He's one and a half years old and he went pee in the potty. Incredible. This kid just keeps surprising us. Not to denigrate our parenting abilities, I think we are perfectly wonderful parents, but the mister certainly makes things easier on us. He is such a clever little kiddo, and so observant. Lately he has begun to let us know, sometimes, when he has to go or when he does go. He is fully aware of what he has down there (just ask him where his "peh-peh" is, he's very forthcoming), and he seems pretty interested in dealing with it like the big people do. Today he told BL "Ah peh-peh" (I pee pee), to which Andy asked him if he needed to go. MR ran into the bathroom and with BL's assistance used the toilet. He, and we, were very excited. Andy went out and got him his own little potty, which he has already asked for (and used) three times since. Don't worry, we do possess a healthy amount of hubris and aren't going to count our chickens before they hatch- but it is pretty cool that he is even approaching the subject of toilet training. And with enthusiasm. We figure we will strike while the iron is hot and see where it gets us. Having number one trained by the time number two arrives would be almost too much to ask for, but it won't stop us from trying.
