I do think that having classes about child development should be mandatory in high schools. There can also be some things discussed with younger children to help them understand their own development too. There should be discussions on verbal abuse as well. I don't feel that someone should "just" become a parent without proper education so they do not verbally abuse or hit a child and understand child development better.

Unfortunately when I was growing up there was not as much guidance available to parents as there is now.
