My son had his 5th Birthday on Friday. He has been urine trained for the past year or so but he refuses to have bowel movements in the toilet. He doesn't ask for a diaper, doesn't have a bowel movement at the same time of day or anything that helps indicate when he needs to go. He will just suddenly be poopy. About a year ago, we put him back in pull ups because we were so frustrated with cleaning up messy pants - he responded by no longer using the toilet at all. Now, he wears big boy underwear all the time and just messes his pants every day (sometimes twice a day). He is lactose intolerant and has suffered chronic diarrehea his entire life (not fun to clean up!!!). We have tried every reward I can think of, we have tried completely ignoring the issue, we have about every poopy book they make, and nothing seems to help. I feel very desperate!!!!!
