I'e never heard child-free to describe anything other than a period of time away from your kids- gran has the kids this weekend so we can get things done child-free. But I might start using it now. There is nothing more heartbreaking than having to explain, justify, excuse why you don't have kids- I feel this a lot as I bloody love children, worked as a nanny for many years, yet can' have my own.
The conversation tends to go- where do your children go school/how old/how many, because people assume children particularly if I mention my job. If I say I don't have any the 'yet' always seems to be implied. Plently of times speaking to mums at playgroups and in the playground, so most of my social life when I worked full time, it's kind of a shock statement to say I don't have any myself. It isn't simply stating something, it's breaking an assumption and hurts every single time.It can be hard for a parent to understand this, I don't mean those who struggled themselves or had other issues.
I adore children, always wanted them always will, but will never have them. And I know the answer to that is usually 'have you considered' as in have you considered adoption, fostering, surrogacy, IVF, going vegan (said by a friend in a serious tone, because not eating ham will certainly cure my infertility). Yes funnily enough I have put hours of thought into all options, yet as I'm standing here now with no adopted child or whatever, clearly they weren't options that would work for my circumstances. I'm sure it can get incredibly annoying to those child-free by choice to have to explain it, to see the suprise at being outside the 'norm'. And for those who can't it's a constant painful heartbreak, and if using a different phrase or word will reduce that you bet I will fucking jump on it.
