Gwyneth, youare not alone!!!
I now have eight g,children - no more will be coming. They are aged between 9yrs old and 20 yrs old. I was never that keen about becoming a g.parent. Absolutely loved being a Mum to my six, enjoyed it just as much as they grew to adulthood, so had no desire for babies/children to come between us.
Obviously, not my choice, and all my g.children have been planned and are much loved.
Except for one (who lived close to me and was a single parent), I have never been involved with child care for any of them - except on special planned occasions. THEIR children, THEIR responsibility.
I have enjoyed being the spoiling grandma, who they see on occasions, and know they can get treats from. Even the one I helped out with a couple of time a week, I was still able to maintain that role (spoiling g.ma).
My grand children make my children happy -and anything that does that is good for me.
Yes, I know on some of the threads here, grandparents seem to go overboard about their g.children. If that makes them happy so be it. Not for me though. I had the most beautiful and clever babies ever born - none that anyone else (even my children) had could ever be as good as them!!!
