Oh, I am the same. I have no idea what would happen to dd1 if we were not around (and dd2, of course, but just seems more worrying with dd1 as don't think people would be able to explain anyhting to her).
e are in the process of trying to sort out who would (will?) be legal guardian for dd1 when we are not around.
We asked her godmother, who quite rightly asked for time to think about it. She has not come back t ous, so i guess that's a no. Obviously we don't want anyone to have care of dd1 if they cannot cope, but we are now back at square one. None of my close friends have children yet, so wouldn't ask them to take on a ready made family, let alone one with SN, and my brother would not cope with dd1 (has AS tendencies himself - anger management not one of his best attributes!)
I do feel awful about the fact that I don't worry about dd2 as much, but tbh, aside form the obvious loss of parents grief, she will be just fine. On the other hand, I am the only person who really understands what dd1 is saying half the time, and, more importantly, what she means by what she says. How is she going to make her needs and wants understood without me?
It's a real nightmare
