What’s wrong with training children? Mechanically performed actions are not bad at all! Stopping in front of the road, washing hands after a walk, hanging clothes in place are reflex actions that are produced by training. Whoever explains to the child why to do it and why, is wasting time. You exaggerate the child’s ability to analyze information and anticipate the consequences of wrong actions. It is boring to listen to him. But I ran on the road - I got the backbone right away - it works great!

When a person, even small, understands the meaning of his actions, he should not be trained. Just enough to remind. I tell you this as a person whose adults have grown up very successful children.
