I'm late 30s, happily married and childfree. My mum has said a few times that she's sad I'm not having kids and worries about my future with no adult children of my own. I'm very close to my mum, and I can see how much she enjoys having a family later on in her life, but kids are definitely not for me.
I just wondered how common this was? If you have children who have decided not to have their own kids, do you ever worry about them?
