What I do know is that Maddy has progressed in leaps and bounds from what she was like a year ago. Watching her has taught me if we stop focusing on the past, it frees up our time to enjoy the present.
Today, she is able to walk past a strange man wearing a hat and glasses, sweeping the end of his driveway with a push-broom; something thich would have caused panic in the past. Now she looks to me for treats. So my pockets may always have dried up bits of cheese or liver or chicken in them, but thats OK with me.
