There’s a book on this topic that was groundbreaking when it came out, called Regretting Motherhood: A Study by Dr. Orna Donath. The backlash was insane. This is a topic that simply wasn’t discussed, and as the book became more famous (was translated into multiple languages, received a lot of public attention), the responses also became more incendiary. I had the utter honor and pleasure of studying with Orna - she read us some of the death threats she received, in her calm and measured manner, using them to further show just how deeply society expects motherhood of women.
I haven’t read the book myself, but knowing Orna, and having read some of her other work, I wholeheartedly recommend it.
