Education and corporeal punishment
At first, corporeal punishment was the primary tool in the education process. In the 17th century, philosopher John Locke urged parents to use praise to stimulate children to learn and behave well.
The fashion then was for a wet nurse to feed a newborn, and then the child was passed on to grandparents or poor relatives for a salary. The child would return home around age five and be educated by the biological mother. Rousseau condemned all of this. After Emil, it became fashionable for the mother to breastfeed her child.
