after six things change a lot.

The child becomes more independent of the parents, sometimes he is even impatient with them. He is more interested in what other children say and do. He develops a consciousness of responsibility regarding the fact that he considers important. He is sometimes tormented by conscience because of actions that seemingly absolutely meaningless, for example, overstepping through a crack in the sidewalk. He begins to be interested in topics that are not related to him personally, for example, arithmetic or the construction of an engine. In short, he begins to detach himself from the family and seek his place as a responsible citizen of the world around him.

Think about how this differs from a child of three to five years. The three-year-old child openly admires his parents. He believes in everything they say, wants to eat just like them, dressing in what they pick for him. He uses their words even if he does not understand them.

Millions of years ago, our ancestors reached physical maturity early, as is the case with animals. They developed the body of an adult, but the consciousness remained, probably, the same as our five-year-olds, whose life is based primarily on imitation of adults. Only much later a person developed the ability to become independent of his parents, to live in cooperation with others, according to the rules, to control himself and invent new things. The individual takes many years to learn how to live as an adult in our complex world. This is probably why people have such a long period of physical growth. The baby quickly grows in size, like an animal, and this happens to the adolescent in the period of reaching puberty. But between these two periods, growth slows, especially two years before the time to reach puberty. As if nature says: "Listen! Before you acquire a strong body and developed adult instincts, you must: first learn to take care of yourself, control your desires and instincts with the wishes of the others, learn to live with others, understand the laws of behavior in the world outside of your family, learn what livespeople".
