My kids and grandkids have been the greatest joys of my life. But parenthood is not for everyone. As someone said, even if you have children there is no guarantee they will be the child of your fantasies, or take care of you later in life. I can't imagine not having them, but I also fully support anyone's decision to not have them. In fact, I have to admire those who do make a choice rather than just taking whatever happens. You might regret the choice one day, but that's life. A lot of people regret the children they did have.
