Hap hap hap hap happiness!

He's running, jumping, climbing, riding, laughing! Two months ago, he would never have run up or down the hill without me holding his hand. Today, he took off running through the tunnel and before I could catch him he had run up the hill to the sidewalk. Sure, it's a safety concern but I have tears in my eyes. No wonder he's so happy! He can do so many of the things he has wanted to do for so long!
