Breaking 'developments'

So, tonight while playing on the floor, I look down and what do I see??? I see Kemper, up on his hands and knees, rocking back and forth....what?!!?

I think he scared himself after a few minutes, but at first, he was all smiles!

I have a feeling it won't be long before I start on the "Chasing Kemper Diet and Exercise Program" cause when this kids starts moving, he's not gonna slow down!
