Bob,
I didn't see this until just now. I had also missed a couple months of posts here, though my computer issues pale before the ones you've faced with Thomas. He's been in my prayers since the first time you mentioned the problem, many months ago, and continues to be.
My youngest had tubes at a very young age (and still does at 10) - from the beginning, they have been a wonderful relief to her. We didn't hesitate at all about her age at the time, in large part because my eldest is the practice administrator for a wonderful group of Ear, Nose, & Throat physicians whom we knew well and trusted explicitly. We've never regretted our decision. It has made Cae's life so much better.
Continued prayers for Thomas, his Mom and Dad, and his grandparents!
Many years,
Neil
