Mar 10, 2012 Rolling Over My son rolled over today, but I think it was an accident. While he was lying on his back, he lifted his whole body using the back of his head and his feet. His back was arching so much that he was able to propel his weight to the side in order to flip. We found his rolling over from back to stomach very exciting. We then spent the next hour trying to coax him to do it again.
