Oh, this is such a lovely piece of writing. It will be interesting to see how your boys perspective on growing up with a disabled sibling evolves as they grow older-leave home, start families of their own. I suspect that it won't be until then that they will realize what it has all meant for you and what an amazing job you have done.
I'm visiting after reading your beautiful post at Varda's. Wise and wonderful.=)
I loved this, and left my comment there. xoxoxo
