Potty Time Continued

So potty time has pretty much been going as described in the previous post with David pooping in his pants, sticking his hands in his pants and wiping it all over the place. I will describe one incident over the summer. We are at Nonna's pool, long disgusting story short, David poops 4 times in his bathing suit. Why not put on a swimmie diaper you ask? I kept saying he can't poop again but he kept on going. So needless to say, I was losing my mind. After the 4th time I strip him naked and hose him off with the hose outside. Nonna comes home from work and lets them inside. David is still naked, and I am packing up to leave. David proceeds to poop and wipes it all over Nonna's rug, window seat and very expensive curtains. I flipped with many expletives flying as I cleaned everything. Of course, Nonna said it's ok but Mommy totally lost it. I have been keeping pull-ups on him because at least they keep the poop contained (until he sticks his hand in it) So that is how it's been going until YESTERDAY 10/9/10. David pooped in the potty for the first time EVER!!!!!!! He was grabbing his butt and I rushed him to the potty. Usually he just screams and cries, but this time he sat down and it slid right out. I was screaming like a lunatic with happiness. David was so happy b/c I was so happy. And today he did it AGAIN. He did most of it in his pull up and he still touched it, but when I put him in the potty he pushed some more out. I was really starting to worry that something was wrong. But everyone said he will do it when he is ready. Hopefully this is the beginning...
