This. :iagree:
I had a friend who died when she was 50 and she 2 had school aged daughters. I would ask her what you can do to help her make memories for her daughters. In addition to helping her write letters (my friend did this), you might see if she wants to record herself reading some favorite stories to her children.
Take a freezer meal or two when you go. Even if they have extended family surrounding her, no one wants to think about cooking at a time like this.
Just be there for her...it's so very helpful.
