Has anyone got any tips/advice for me and my 5 yr old son (yes 5yrs old!). He won't use the toilet to do a poo. He holds it in all day and waits until he's got a nappy on at bed-time (he's not dry at night yet) or until the morning and does it in his nappy. He has been known to do them occassionally in the toilet, so I do know that he can manage it. I've tried everything from star-charts to getting cross to ignoring it completely and just as I think we might be cracking it, we seem to go backwards.
