Could it be? Could he really be potty trained?

Well, not completely, but very close. He tells us now when he has to go, or will hold it until we tell him we have to go. Accidents are very rare now. He is so proud of himself. We are very proud too.
Funny thing... Tony told him that it was ok to pee outside. So a few times now he has told me that "Vinny went potty" and when I ask him where, he brings me to the slider to show me that he peed outside. Now we just have to break that habit...
