Matthew has learned that he can change his position when he is lying down on his stomach. As you can see from the photo, he was on the floor. He had shifted from the mattress onto the floor. Mike was attempting to teach him the techniques of crawling, but of course, unsuccessful.

From reading books, I understand that the ability of shifting position is also a step towards crawling. We are looking forward to see our little boy crawl, but it also meant that we got to start babyproofing our home! Hahaha...
