The Battle of the Big Bed

We have started to try to get Jackson to sleep in his Big Boy Bed. As anyone with kids know, it is a battle.
With JET III on the way, we are hoping to use Jackson's current crib and just transition him into the Big Boy Bed. It sounded so simple to us naive parents.
We started a few weeks ago by putting toys in his new room with the bed, calling it his bed, just getting him used to it and last night we decided to start the War. He does understand that it is his bed, but just thinks it is a real fun game to get up and down, up and down, up and down.
7:30 the battle starts. His normal bed time is 7:00, so we waiting a little longer. We tell him time to go to the Big Boy Bed and he immediately goes to his new room and climbs in bed and lays down. This is going to be simple.
7:32, He is out of bed, and the door is open and he is laughing.
We now try to read him a story again, and then sit in the rocking chair in the room to calm him down.
8:00, this has failed, so we try the crib again. We were going to let Jackson win this round.
8:15, we hear a Massive thud. We run up and he has flipped out of his crib, so it looks like the Big Boy Bed is staring us in the face again.
We let him stay up to play some more to tire him out.
8:45 Big Boy Bed time again.
This time we try to keep the door shut thinking he will tire himself out.
9:30 rolls around and 45 minutes of on the bed, off the bed, on the bed, off the bed and then banging on the door, we try the crib again with the hopes of not climbing out.
9:36, he is fast asleep in his crib. Jackson wins.
10:30 we move him to his Big Boy Bed so hopefully when he wakes up he will feel safe.
2:00 am. He is up and crawling into our bed...back to the crib.
8:00 am. He wakes up for the day.

Back to the drawing board of what we are going to do tonight....With a new baby on the way, we might as well get used to lack of sleep again.
