My mom was 43 when my nephew was born, 44 the next year when my DD was born. My brother was 19 when his son was born and I had my daughter at 23. I know she is glad to have been a young grandma. She's only 65 now, but has debilitating osteoarthritis in both knees. While the kids were younger, she was able to do lots of stuff with them.. zoos, amusement parks, beaches, boardwalks, water parks, etc.
