Thanks so much ladies. He doesn't want to wear nappies and we do lots and lots of nappy free time at home (with both me taking him to the toilet and we not taking him but racing him to the loo when he suddenly looks like he's going to go, so I know he's not ready, but was hoping magically that maybe I was wrong!

Arcadia I know you are right about some kids being older. My DD was months and months after other kids the same age at our playgroup, but then was the first to be completely night trained shortly after she was day trained. Just when you think you can manage anymore, kids suddenly change!
