A good Plan? Maybe? Maybe Not?

I dunno when did Maoster began sleeping late at night at 11pm - 12 midnight. As he gets older he seems to have the ability to stretch himself a little to exhaust all of his energy, beyond his bedtime hours.
Aung and myself decided that this has to stop.
We cannot sleep at 12 midnight - we need to hibernate and we love our former arrangement of sleeping by 10pm.
So a plan was formulated and executed.
We dragged Mao to bed by 9pm made him milk and switched off the lights.
10pm - his eyes were still big. He has been rolling, doing his rock and roll and attempts to run out of the room.
I dunno when did he fall asleep eventually becos I think both of us fell asleep before him. He outlived us that night.
However at 5am the next day, he woke up laughing, playing WIDE AWAKE!
We were so agonised.
Our plan was so backfired cos after milk at 6am, he went back to sleep until 9:20am!
He had another round of milk at 10:30am and refused lunch at 12!
I am so dead. So i am tired becos although lights were out by 9:30pm, he was kicking and playing with me until at least an hr or 2 later and he woke up much much earlier and refused to eat!

Ideas for more plans please!
