Unk, you left out a vital part of Zac's therapy in that explanation (thanks for that by the way, it is interesting how they treat kids like Zac) and that would be Grandpa Therapy.
Looks like Grandpa therapy seems to be working EXTREMELY well for Zac.
BTW, I have been getting emails occasionally from people I gave Zac's name to for prayer chains and they email to get updates on how he's doing. I usually copy your posts and send back to them for their update. I hope that's ok? My neighbor who walks everyday, now greets me when she sees me with: "What's the latest on Zac?"
He has lots of people pulling for him.
