One reason I think this is the case is because working with children, broadly teaching, pedagogy etc. is also something that needs to be learned. Parents in the past realistically did not have the time to spend so much time with their children. We have more time now, but lack the skills (in general) to do it effectively. What I see often is kids not really having the freedom to make mistakes and figure out things on their own. In my case I realized how bad I am at teaching during covid lockdowns and home schooling. The desire to help was there, but it's difficult to grasp the level the kids can understand. One solution for me was to say, work on it on your own, and try as best as you can. Doing it wrong is allowed and if you are really confused, ask me. But with a lot of parents, they run around their kids trying to help them do everything right from the beginning. I just don't think that can work.
