My 4 yr old son won't poo on the toilet but insists on using a nappy. When he needs to poo he hides in a corner only coming out when he's finished. When we've tried him on the toilet he just tells us it won't come out and is obviously holding it in...
He uses the toilet fine for weeing.
His twin brother is using the toilet fine.
Have tried sticker charts and rewards but nothing seems to work. Any ideas?
