Just reading your recent post so I probably wouldn't do this but something I was thinking earlier, if he can hold on like that all day. I wouldn't put a nappy on him at all ever... I would tell him that its such a good thing he can hol dit like that sohe doesn't need a nappy at all.

Of course he is likely to just wet himself & you need to be prepared to deal with that. But I wonder if he just had to go to bed with out it & out to the shops etc with out. He wouldn't have something to hold off weeing for. Like if he knows I can wee & poo at bed time as the nappy goes on then... What is he going to do when it doesn't go on?

But yeah reading your recent posts. I would seek some professional help before trying anything too drastic like that.
