Where is my Good Sleeper?

Typically our evenings consist of bath time @ 7:30, bottle @ 8:00 and he falls asleep immediately after burping. That seems to be changing as of Thursday night. Chad went out to check on Kade in the middle of the night and found him on his tummy. Normally, Kade falls asleep on his back and stays the same way all night. I have a positioner I use to make him feel cozy and it helps him to stay in one spot. Well not anymore, Kade had turned over and ended up on him tummy (still in the positioner which I can't figure out).

So last night, I went to put him night night and he immediately turned over on his tummy and "swam" his way around the crib looking at his bumpers w/horses, cows, barns, and tractors on it. Then he gets mad because he can't turn over on his back and is not used to sleeping on his tummy. So we turned him back over (just kept rolling over again), tried rocking him to sleep, tried holding down his legs for a while thinking he may just fall asleep before he can roll over...nothing worked. So he spent his first night in bed w/mom & dad.

More like w/mom though. He started off in the middle of the bed towards the top so he wouldn't get his face in the covers. Well he continually worked his way over to mom and I had to sleep in some weird positions. I woke up w/ a terrible backache and dad was all sunshiney telling Kade what a good job he did sleeping in the bed. GGGGRRRRR!
So we'll see how things go down the road but I have a feeling our days of him going to bed immediatly are numbered and we may have some challenges ahead of us.
