Good for you Pebbles...
I understand the dilemma of having a grandchild involved and so innocent.
When you are mentioning the forwarding address and how..more-than-likely she won't take care of it. It reminds of when my kids didn't take care of their business and then when someone arose where it slapped them in the face......they'd say "Something always happen to me. I don't know why things can be easy!"
Ugh!
