Debbie, I know this is a longshot and you've probably already investigated it, but could the eating problem be caused by something in his mouth? Perhaps a sore tooth or maybe a canker sore? Of course with all the meds he's getting I'm sure you've had a look....but...just in case....

Good to hear that he's showing an interest in things now. It can only get better from here.
