he's excellent as long as he's got no bottoms on. he's ok with pants although only pokes his willy out of the side.. but as soon as we put trousers on him he's back to wetting himself. i think he's also, subconsciously or otherwise, 'saving' poos for when he's got a nappy on. how can we help him with the trouser issue? he's tricky because if we ask him if he needs to go he always says no and really only goes on the potty when completely left to his own devices so he doesn't really accept help!
