Ok, this is a little off topic, but when we wanted our children potty trained we would drop them off at my parents for a weekend, and at the end of the weekend the kids were potty trained. My Mom's secret? She would have the child walk around naked for the weekend, and there was something about their nakedness that prevented accidents. Amazingly enough, it worked.
Ahh, pee-pee on the floor. I don't miss those days!
