Poop Happens while Potty Training

We've been potty training the boy for quite some time. And every time I say he's potty trained a major accident occurs.

I've been washing out poop underwear all weekend long. Some days, I just throw them out but it's getting to the point where he may not have any underwear left. Usually I can catch him and run him to the bathroom before it gets ugly. Today however, he made it to the bathroom all on his. I found him sitting on the toilet holding one square of toilet paper.

"I'll clean it," he says. He's smiling, looking proud of himself and crumpling the toilet paper in his hands.  "Good job," he says. I forgot to say it. I'm too busy scrubbing his hands with a wipe - the last thing we need is pink eye.  (Yuck - I'll pass on that. Thanks!)

His shorts and underwear are on the floor - in need of a serious rinse.  It's the second accident of the day. I pick them up, tempted to throw them away and then I realize they are brand new. And who the hell am I to throw away a brand new pair of Spider Man undies?
