DS is screaming and holding a poo in. He is on lactulose but I think the problem is more psychological than physical. He drinks loads of water, does lots of exercise, not too much fibre but enough, loads of fruit, no bananas, so i know there is nothing I can do. I have tried to insert the suppositries given by doctor but this is impossible unless I have someone to hold him down. I am at a loss and looking for advice to prevent this re-happening and advice to encourage him to release the poo.
TIA
