Congratulations ! The coming grandchild is wonderful news and I am sure you will be a lovely grandmother and get huge joy from this new member of your family. I won't add to the wise words others have written BUT suggest you could focus on doing something very special for the child and the parents - I've written about this before, but it really is a great idea which has lots of unique meaning for the family. So, when you get the first baby photos you can start writing letters to the baby, including the pictures. When you can see the baby, you can add the 'story' of your seeing him/her full of interesting and telling details, for instance, the pet names the parents use. Continue to write these letters every time you see the child - the child will love to receive them - in my family my grandchildren call them the What We Did letters. After 10 years I had the What We Did Letters for two grandchildren turned into a book, with a copy for each family member. These books are treasured and will, I guess, be looked at with interest by my great grandchildren! You can do something really special which will be appreciated by the parents and the children too.
