DS is 3 next week. He hasn't been able to poo since birth and has been on Movicol and suppositories since he was 4 months old. No one has ever been able to tell us why. He was diagnosed with CMPI at 1, but removing milk from his diet made no difference.
He really wants to potty train. He can hold his wee and will do them on the potty without a problem, but he can't poo! We can't get his movicol dose right - Either his poo is like water, or he doesn't go at all (He can regularly go 9 days without). Often, his poo leaks out (overflow?) and there's nothing he can do about it. Then we're back to upping his movicol hugely and gradually dropping it until he has a normal poo. It never seems to work though - What he needs for one day seems to not work the next. We've been doing this for years!
He doesn't show any signs of withholding, but does complain his tummy hurts when he hasn't been for days. We've tried watching videos and reading books. When I ask him if he wants to do a poo he says "But it won't come out mummy". Never complains that pooing hurts.
How on earth do I potty train? He starts nursery in September. Help!
