Today he proved this when we took him to the playground, and he proceeded to climb up the rock stairs on the playscape and come down the slide. On his own.
At first it scared me; I didn’t want him to get hurt, and every maternal instinct I had kicked into overdrive. But then, he was having so much fun, I didn’t want to prohibit him, either. So I watched over him closely as he tested his new limits. Up the rocks, down the slide, over and over! Way to go, Maverick!
