Sorry hun, can't really help
But Jack does exactly the same, he has started waking in night about 4/5am so i bring him downstairs with no lights or telly etc... and 9/10 times he will go back to bed for a couple of hours
but if Ant gets him up and does same routine he won't go back and comes full of life and wants to play, so is knackered when i am trying to get Em ready for school
I think it is a dad thing to be honest
