New great grandchildren

This should be a very happy time as  there is breaking news with the births of a great grandson who was born Sept. 10th  9 lbs 4 oz and today Sept 16th a great granddaughter was born 6 lbs 10 oz.  I feel happy and yet I feel sad. I think because tomorrow Bob will be gone 5 months. I thought I was doing good but now I keep thinking about things I should be doing for him, then remember he isn't coming back to our house.
