I have two daughters, in their teens, and both have said that they are not interested in having children. I'm glad that they are giving both thought and pause here, but I'm also secretly hoping that they change their minds when the time is right for them.
I'd be happy with and without grandchildren, but it would be incredible to be able to give all of the love that I can when I am retired, when I have less going on in my life and the time to do so.
