S.,
You don't mention if you live close to your mother. If you do not then I would send a card to let her know that your thinking of here, praying for her during this time. If you live close enough to visit her maybe you could do something together in honor of grandmother. If there is something that grandmother really liked to do, visit a museum, go for a walk, prepare a special meal or food you could do that in honor of her memory. God Bless
