I am 58 and childless - I felt that with my depression issues it would be unkind to serve out to my children what I had to put up from my father. I am sure I was right about this, but if my wife had wanted children I would have been open to discussion, but she did not.

We childless people do feel a certain wistful sentimentality about children, but this seldom lasts very long when you come into contact with the real thing! We have cats as child substitutes, which is rather pathetic when you think about it. You make your choices and live with them. I hope this helps you.
