Yeah, most of this I did learn in school. Not the last bit, but the parts about the placenta ripping out and the uterus contracting was definitely in my books. As was postnatal depression, and sleep deprivation.

I went to American schools growing up, can confirm. I was lucky enough to be in a fairly modern part of the country and the sex ed was well intentioned and we got more than one year of it - but matresence was never a topic.

Not American. We did have a (rudimentary) section on reproductive anatomy in high school biology, but it didn't really go through the full process of pregnancy, childbirth, and the physiological effect it has on the body.

Oh, and the teachers skipped it completely in biology class because they didn't want to deal with a class full of teenagers snickering their way through it, I guess. We were told to just read the textbook.

im canadian we didnt learn shit about any of the things after birth. Im not even joking it feels like we skipped the entire 'after birth' chapter of sex ed....it was weird.
