Lizze and I are really heartbroken over the amount of regression Gavin's been experiencing lately. Today was particularly difficult because Gavin was clearly struggling in many areas.  On one hand, I sent Gavin in to Clearwater to refill one of our five gallon water jugs, while I watched him from outside the store. He had to buy a token, lid and then fill the jug up before carrying it out and putting it into the trunk. This is only the second time he's done this and he did a really good job.  At the same time, he can't remember how to type the code into the keyless entry on the front door. He's been able to do it for the last two years, but lately he can't remember the code…
