Having him go commando scares me! We actually go to test that out a few days ago. We were at the car dealership, he had a massive poopy diaper and I had no extra diapers with me. So he got to run around with just pants on. He peed twice. But, I think that's what got him really interested in wearing undies and going in the potty. We haven't gotten a chance to get him started with the potty training yet because my husband and I are finishing up finals this week. I'm hoping that after we're done with school we can get him going. He's started telling us immediately when he pees or poops in his diapers and he often asks to wear the training pants instead of a diaper. He's even waking up a little drier, so we're very excited. For some reason I just feel unprepared or like I don't remember how to do start the process. I think I'm just overwhelmed with finishing up this school term, waiting on the baby, Christmas, etc.
