Happy birthday Turner!
I understand the extended family thing. It's probably not that they don't care, but that people don't often know how to approach the subject. I find that often times people ignore that the kids have autism. In a way, it's great, we all want our children to be treated like every other kid, but sometimes it would be nice if others took a more active role in the care of our kids. I even asked my cousin to come watch one of his therapy sessions. She never really asked how he was doing, but I told her it would be important to me if she would come watch one, and she did. Sometimes you may find if you ask others to take a more active role, they will.
There is nothing I hate more than people who want to show off my kids. They have no interest in their day to day lives, yet on special events, they cannot wait to show the off. They act like they are so proud of them, yet never make any effort on any other day.
