You might check with the kids to make sure they know how to do 911 and such ... not to scare them, just to make sure they can function in an emergency if they are ever at home alone with mom and she has a serious reaction ...

you might also teach them how to make a simple meal ... sandwich and carrots or something that is age appropriate and they can take care of for themselves or even to do for mom if she's having a really difficult time of it one day ...

Do you know if mom has a particular liking for certain types of books, magazines or a sitting down type of craft ... that might be something you could do that would be easy for her ... just a few thoughts I had today.
