He is fully aware of when he needs to wee and poo but says he wants to use nappies.
Yesterday he did four wees in his potty - much praise etc., but today he has managed one. The other times he has just gone where he fancies - on the post, up the tv unit :( - and when I've asked if he knew he needed a wee he has said he did but didn't want to use the potter or toilet.
How do I fix this?
