Well we have been practicing rolling over and all our hard work finally paid off.
Last night we were trying to get Marc to roll over, but he kept getting tired and laying his head on the ground (which was so cute).

This morning I put him down on his stomach and within 30 seconds he had rolled over. Of course I only saw the very end of the roll, and Matt totally missed it, and Marc wouldn't do it again, but nevertheless, he rolled over!!!

Reading instead of rolling over again like mom and dad want.
