The beginning of the modernist adventure, circa 1890s, held that this was a new

I actually
found the book «Mindful Birthing» more helpful because instead of being cheesy and full of biological
essentialism, it was more exercises for relaxation and focusing (which would be helpful in a lot of situations, not just childbirth).
