Three in diapers

Eddy Haskel was diagnosed with encopresis several years ago. I have tried numerous doctors and self help books looking for a cure. Over the past few months I thought we had moved passed the pants pooping. Every book and doctor that we have ever gone to, have told me he needs to retrain his bowels. I have tried setting timers, letting him have the Gameboy while on the pot, pro-biotic yogurt, Metamucil, Fiber One, almost anything on the market that makes one move their bowels I have tried. Eddy continues to poop his pants. I can smell it the second that he walks in the door, I get angry, I yell, I scream, and that is not what I am supposed to do. I am supposed to ask him to finish having said bowel movement, get him clean underwear, and help him get cleaned up. Well, I do not do that either, wanna guess why? Because I have 2 other kids in diapers. One who is almost more potty trained than Eddy.
Last night I let him ride his bike, it was raining but I needed a break from him. I called him in a couple of hours later and he walked past me and the smell hit me. He sat in my favorite chair, thus causing the smell to get onto my chair. I asked him to go clean up and bring down his soiled clothing. He took a 30 minute shower and has still failed to bring down the dirty clothes for me. At dinner when I called him down, same thing; the smell of fecal matter. I asked him why he came down here when he had poop on his butt; his response was "I did not want you to get mad at me when you called me so I got up from pooping and did not wipe my butt." WTF? did not wipe your ass, came down the first time I called you? Bullshit.
I am tired of cleaning shit out of pants, I am tired of having an almost teenager who still shits his pants, I am tired of being nice about it.
