So far he's been in bed for 2 hours tonight, but he's not keen on getting up while we're still up, he prefers to party at 3am.

Before he went to sleep I told him a story about a good boy who stayed in his big Elmo bed with his best friend Elmo blah blah.

I told him if he stays in bed he will get his favourite book back that DH confiscated last night. I also told him if he gets up, I'll put him straight into the baby bed (his cot is still in his room). Let's see how we go.

I agree, the Gro clock just keeps him out of our room.
