Ah yes, that's such a fun stage. Both DDs did the same. I echo the others, start diapering on the floor. You can get more leverage and if he scoots away he can't fall and get hurt. We had some success with putting stickers on hands, nose, feet, belly, wherever. That kept both DDs occupied long enough while either looking at the stickers or trying to peel them off. I just bought a huge sheet of smiley face or stars or that kind of smaller sticker and it worked for a while.
