Flipping non-stop

Since last week, Preston is able to flip non-stop until he rolls to the edge of the bed and we have to rescue him from falling off the bed.



He also likes to sleep side way at night when we take him out of his sarong and let him sleep on the bed. Sometimes when I wake up, he is already 90 degree from a straight position. I have absolutely no idea how he does it. The scary thing is that, he sometimes sleeps with his face down - thus covering his nose. How can I stop him from such a dangerous act???



Here's the videos showing how he flips non-stop.





One more thing that we noticed just this Saturday - Preston is moving backward after he flips over. Definitely a sign of his eagerness to move about. Imagine when he can walk ... hohoho.
