Mine also ran around the house with no diaper, no underwear, just naked and I would set him on the potty every 45 minutes or so for about 4 or 5 minutes. Basically, he would just hold out...like for 3 days. It worked because usually he would finally go in the potty. BUT in the course of a week, there were times I had to dress him like to go someplace. Then the one and only minute of the 3 days that I didnt have my eye on him (like upon arriving home, unloading 1 bag of frozen groceries & before I had a chance to take off his pants and underwear and set him on the potty) he would disappear around the corner and do it in his pants. I'm sorry, but I just got fed up because his business was sooo intentional, i.e., he obviously had the bowel control, sooo big and sooo stinky after 3 days that I actually barfed a time or two. I even started wearing a gas mask! I'm not kidding. Soon after, I wondered why I had to be the one to suffer like this for so long when I knew he could use the potty! So I went on strike: next time he did it in his pants or night diaper, I took him outside, along with the Dawn, a small towel, and if it was a diaper, a plastic grocery bag. I told HIM to take it off and put it in the plastic bag but smell it first. I also told him to take off the rest of his clothes then I hosed him (and his clothes) off with the garden hose. I squirted his lower 1/2 w/dawn antibacterial soap, told him to spread the soap around and down his legs and on his hands, then I rinsed him with the hose again. He didnt like it at all because I fussed at him and because he was now having to do the stinky work himself (other than hold the hose, I was 100% hands off). I even handed him a towel and told him to do the drying off before we went back in the house (funny how he never was very good at drying himself off until this happened). Under better circumstances he does enjoy the water hose outside on a hot day. Anyway, after a little while I gave him a bath (much better than barfing) but not to link the poop incident with bathtime. We have done the outside hose thing twice and it seemed to do the trick. We've been good now for at least a month. I just hope he doesnt try testing me out on that one again when its too cold out 'cuz I don't think I'll have the heart. If you do this and you have a squirt handle on your hose, be sure not to set the sprayer on anything that hurts or stings the privates. I found the sudden, unexpected, drastic change in the normal routine, along with my making it very clear I didnt want anything to do with that poop anymore -was what made him realize the praise/rewards he got after using the potty was a much better idea. Best wishes!
