That's it really. He's been fine weeing in the loo since he was about 3, but he refuses to tell us when he needs a poo and will just do it in his pants. He knows when he needs to go, and if we happen to see "the look" and ask him if he needs to have a poo he'll say no a couple of times but then say yes and do it on the loo. If we're not in the same room he just won't come and tell us though, although he does come to tell us when he needs a wee.
We've tried bribery, encouraging, star charts and nothing seems to work. We've now put him back into pull-ups (which he doesn't like) in the hope that putting him back in "baby" nappies will make him want to be a big boy by telling us, but 3 days of that and there's no progress.
So any ideas?
