Elizabeth hon no that is an option, nothing to do with being selfish. I have known a few women who chose not to have kids until much later in life, or not at all because of career and such. Or as some have said, they would sooner not bring up a child in such a cruel world.
Either way is a good choice as I see it. There would be no sense in bringing s child into this world unless it was to love and care for that child, and to be proud to be the mother of that child. But if for whatever reason, your life does not include rearing children, then why conceive one?
I on the other hand could not have my own children for obvious reasons so I had then in my care 8 vicariously and three my own. I did it because I love children and for those years I had them under my roof they were all that I truly lived for at the time, they were a good part of my life.
If it would have been possible to have personally given birth to all 11 of those children I would have been proud to do so. Have any idea how it feels to be walking down the sidewalk of your home town with three or four children in tow like a proud mommy duck and her ducklings.
