Thanks everyone. I am trying all that advice. It seems to work sometimes but not others. Less than 5 minutes after he got off the toilet this morning he took hs nappy off and pooed on the floor. I will stick at it and hopefully see an improvement in a few days. I guess the biggest problem is that much as I have tried not to, I have probably shown some reaction when he's done it and now the damage is done.

LOL Christy - the puppy trianing analogy is very apt I think!
