Crisis 1-1.5 years old
This crisis is due to the purely research interest of the baby who has mastered the skills of independent movement. And he is expressed in the fact that his attempts to expand their horizons require maximum attention from parents and often ends either material damage (for parents) or bumps and abrasions (for the researcher himself). It is not surprising that such a behavior of the baby provokes the appropriate reaction of the mother and dad, that is, it makes them be nervous and angry, limit him with a maneen and endless requests to behave calmly. But this is not the most correct reaction, which can instill a child feeling that any activity in terms of curiosity and initiative is bad. Try to give the baby maximum freedom in his cognitive activity, while ensuring its security and adequate evaluation of actions.
Crisis of 3 years
This "failure" occurs under the motto "I myself!". At the same time, the kid "provers" the boundaries can be impossible by manipulations in the form of hysterics, whims and "swing" rights. He feels his own independent person who has his own desires and preferences, and in a hurry to demonstrate them as it can. Therefore, the child who has already mastered the speech, go through this turning point is easier. As you, since one way to successful overcoming is just a communicative connection with the child in the context: it is possible, and this is not. Use also the possibility of providing the choice to your "commander", even if not in such global decisions of the dish for lunch or clothes for a walk. Even such trifles are very important for him now. Give him maximum freedom - let him do everything he wants, if it is safe for him and others. And do not forget about the promotion of all its good deeds and achievements.
Crisis 6-7 years old
This turning time in the life of the child comes when he first independently goes into the light, namely, goes to the first class. First, he leaves from under your total guardianship and learns to solve his problems itself, secondly, he gets into the team where he needs to gain and conquer authority. Therefore, much in his behavior may not be from him, but simply copied with the behavior of peers, and some attempts to settle some questions - not quite successful and even unsafe. Your tactic in this case is attention, participation and support of the child. At the same time, try to develop the abilities of your novice schoolboy: Choose a school or class with a specific slope, a sports section or a circle for interests (but not yours, but a child). Explain the causal relationship of his actions, help the Council.
As you can see, no children's crisis should not be ignored - without you, the child will not cope with him. So be always next to your growing little man - and he, becoming an adult, will not leave you in a difficult moment. https://rus.lb.ua/file/person/4549_polyakov_maks.html
