I never had a desire to have children. I knew this about myself when I was a child myself. I am now 54 soon to be 55 & I do not regret my decision.
Now that said, I wish all who want children & can afford them without tax payer help, could have them. I support adoption & fostering children. I also believe some people should not have children of their own nor be able to be in the same room with any child.
If you are happy with one, I'm happy for you. Raise them well.
