He hasn't worn a nappy for over 12 months. Has no bed wetting of a night. No worries with peeing but I've tried everything and he keeps pooing his pants. I think we got him to go to toilet for about a week then he went back to dirtying his pants. I've even taken him to doctors but was told to persist with it. I've tried sitting him on toilet & not letting him get off until he's done a poo, but he will just sit there n when I finally let him off, within 1/3 hr he poos his pants. I've made him clean his own solid pants but nothing seems to work. Has anyone else had this kind of problem and what worked for you.

Am really at the end of my tether with having to deal with dirty pants every day.
