Tai Chi?

Zach just took a short walk across the stage, waving his arms at the orchestra in front of him. (One of his first "legitimate" walks, actually traveling more than a couple of feet.) OR maybe he was practicing Tai Chi. I'm not sure yet. But he's really figuring out the walking thing.
Stay tuned!
Of course, that experience tuckered him out, so he's now lying spread eagle on a his mini-quilt on the floor, waving a spoon, or is it a wand?
