DS is 2.9. Has decided he doesn't like his nappies and refuses to wear them. But, he's not interested in using the potty or toilet either. On the plus side, he can hold it in, but he lands up holding it in for hours and hours (we're on 5 hours right now for example) until eventually he's forced to let go. Not sure what to do. Forcing him to wear a nappy seems a bit counter productive, but I worry that too much holding can't be good either.
Any advice?
