So I think the so-called prenatal education in ancient times was that parents would talk to the children in their bellies, touch them gently, or pour out their thoughts on their children's future development, or hope that their children would grow up after birth, but now there are no such things as music and prenatal education courses. After all, for ancient people, there was no education before children were born.
Moreover, I think the key reason why there was no prenatal education in ancient times was that in the feudal society at that time, women's social status was generally very low, coupled with the idea of son preference, the child was not born and did not know the gender. Ancient people's attitude towards pregnant women was not particularly good. Anyone familiar with rural life knows that girls still have to work to support their families when they are pregnant.
So I don't think there was so-called prenatal education in ancient times. Although the ancients also attached great importance to raising offspring, for pregnant women and unborn children, prenatal education was completely unnecessary or unexpected in their minds, and they did not attach as much importance to it as they do now.
