Lots if not most people on here seem to be grandparents.
My daughter and I were talking and it made me feel so sad and guilty that my children don't have any close relatives in their lives. We live far away from where I grew up, my mother died a few years ago, but because of distance they only saw her every couple of years or so. Their father's mother has absolutely no interest in them, for years distance was part of the problem too, but when there were visits she would basically totally ignore them, only if I asked her to may be read a book with them was the extent of the connection. My grandparents either died when I was very small or before I was born, so don't really have many memories of those relationships, but aunts, uncles and cousins were part of my growing up.
My daughter says she doesn't feel she missed having grandparent's, sort of not missing what you don't know I suppose, but in the same breath says she feels she's missed out on having family around. My children are in their 20s and 30s now, and can't change what was, but it's silly I know, I feel sad and a sense of guilt some how that they missed out on something very important.
