It was just the teeniest of steps, and had I not been on the floor playing with with him, I would have missed it, but I think what I saw counts as a first step. He pulled himself up onto the entertainment center (one of his favorite toys!), and turned around to smile at me, then one at a time picked those little feet up and moved them forward. I squealed with glee (which he promptly mimicked), and we laughed and hugged. Just a fleeting moment, and one no one else but Aaron and I shared in, but one that I'll remember for a long, long time. Everyday brings something new, and it's such joy to watch.
