It's a documentary film that explores the history and culture of women and their decision to not have children. You can rent it on Vimeo for $10 (which is a bit much to rent a movie, plus I'm a Roku user and Roku doesn't have a Vimeo app, so I had to screen mirror my phone to my TV just to watch it).

Although I am not a woman, I do identify with this film because of the points addressed as to why these women choose not to have children, which range from wanting to focus on other things to simply just not wanting them. This subreddit even got mentioned in the film because there's a 19-year-old woman in the film who wanted to get sterilized, but had trouble finding a physician willing to perform the procedure on her: she consulted the wiki of this subreddit to find a CF-friendly physician and ended up seeing one in Seattle (which I thought was pretty cool because that's in my home state).

I'm glad this film was made because I think it's important to recognize that becoming a parent is optional and there's no shame in choosing not to have children.

Edit: One point I'm glad the film addressed that I don't see brought up often is that childfree people have given more thought into having children than those who had them, which I completely relate to as I got a vasectomy because I had given a lot of thought towards having children.
