Thank you. It is so much a personal choice. It would be remiss of me not to suggest a little amendment in your terminology use. Childless refers to people who want children but can't have them. There isn't choice involved. Childfree refers to people who choose to be childfree.

I don't have children by choice. I am not missing anything. I am not less anything. So I am childfree. I hope this makes sense. Language and semantics are so very important :-)
