Yes! I've recently discovered lots of child-free (and some single) content creators on Instagram/Facebook etc - I'll list them below and a quick search of socials or Google should find them:
Lucy Meggeson* - she has a podcast called Spinsterhood Reimagined, in which she talks to different women and men about reclaiming the term spinster as something positive, and recognising why being single and/or childfree can be really great.
Shani Silver - author and podcaster - wrote A Single Revolution and is great on insta for child-free/single positivity posts.
Jody Day - founder of Gateway Women and author of Living the Life Unexpected which is about her coming to terms with her being a child-free woman.
Melanie Notkin - founder of the Savvy Auntie movement, which aims to celebrate the aunts of the world as having a valuable place in society, even if the children they care for are not their own.
Polly Vernon - journalist who is in a relationship but chose to not get married nor have children.
Ruby Warrington - journalist and author of Women without Kids
Anna Olson - runs a podcast called We're not kidding and is a life coach who supports women who are struggling with the decision to be childfree
*Hand on heart, I think discovering Lucy's podcast might have saved my life in the last year. It's totally reframed how I view my situation, made me feel so much better about my life and introduced me to other people in this sphere (many mentioned above) that also have interesting or helpful things to say.
I was struggling so much when I came out of the other side of the pandemic last year and realised I was staring my 40s in the face as a single child-free woman. Discovering that I'm not alone and there are others out there like me has really helped.
Hope you find the above helpful! 😊
