Karen he's been great at night. We've used a crate and the very first night he cried twice but the past 2 nights he's slept through. He took himself off to bed last night! He's been dry in the morning so far and uses the paper well first thing. Sometimes afterwards he then forgets! He'll be playing and then just have a tiddle - however teaching infant children I see much the same thing at work - to engrossed I think to realise he needs to go until it's too late!
Reading the blog it looks like a collar should be the next thing to sort out. It's so useful being here!
