Aww, Wendy. I'm sorry to hear DH isn't very supportive. It's so hard when you're the one that has done all of the work, research, dragging the kids to appointment after appointment trying to exhaust every possibility.
{{{{Hugs}}}} to you and you're doing a terrific job. I hope Tyler is doing well.
And don't worry about Zach (I know, easier said than done), Ben told me the other day he was going to run away. HE IS FOUR!!! I think we're so mentally drained from the medical issues that some things are harder to take than they usually would be.
