Inspired by his buddy Lucy, no doubt, Shaw is taking a new step toward the world of self-ambulation: the butt, or bootie wiggle, whichever you prefer. This involves, first, a roll from back to belly.

Torso and face planted, the legs pump and pump even propelling the little man forward a few millimeters. Huzzah!
