Brilliant piece, thank you for writing and sharing. I will share it up on my twitter (childfreebychoice).
It's really great to see it written like this. When parents say they know what it is like to be childfree I can never articulate exactly how they don't. Their lives have been arranged and stacked, geared towards having children. For many years before children come along, parents live their life in anticipation. The purposeful childfree do not.
Thanks for this
