I just came across this on the one hand endearing and helpful and on the other hand rather ickily normative Disney movie.
The Story of Menstruation is a 1946 10-minute animated film produced by Walt Disney Productions in 1946.
It was commissioned by the International Cello-Cotton Company (now Kimberly-Clark) and was shown to approximately 105 million American students in health education classes.
I mean, Carrie would have felt better for having seen this, surely, but oy! the admonitions to eat healthy and not get colds, or even worse: to look nice and stop feeling sorry for yourself, do grate the contemporary nerves.
