I should warn you.. this one is a doozy! Ok, I am a mother of 3. I PT my first son by 2.5 w/ little issues. I mistakenly thought son number 2 would be a cinch...WRONG. I started PT the summer b/f he turned 3 and he went poop on the potty one time w/o help from me. After that one time he wouldn't go again. He is 4.5 now. He is still refusing to poop on the potty. I have tried virtually EVERYTHING. He has gone poop occassionally when he has been sick with diarrhea and I think , "Ok, this is it he gets it now." Wrong again. It is a HUGE control issue with him. He does get it. He just won't do it. I have tried bribes, cleaning himself up, you name it. He does not wear a pull-up during the day and will just poop in his undewear. He holds it b/c he knows he is not supposed to poop in his pants so he just does the little poops all day. He goes to preschool and hasn't had an accident there and he is there 2x a wk for 4hrs each day. When he does go in his pants we make him sit on the potty for 5 minutes each time. NOTHING. He will poop his pants in front of his cousins and friends and does not even care. He would sit in it all day if I let him but he just stinks too much for me to do that.
