The crisis of one year in a child is a natural stage of development, occurring in all children in approximately the same period (plus or minus three months). It is connected with serious changes in the process of interaction with the world and the acquisition of new skills, greater independence. During this period, the child becomes available vertical movement, an independent choice of direction. Such abilities open up opportunities for knowledge of the world and entail a desire to actively interact with previously unknown objects. Children tend to try to touch and taste what they have not previously contacted, and the criticism of the degree of danger and the ability to cope with the tasks has not yet been established, which adds problems to parents.
In addition to knowledge, another active function is being formed - defending one's opinion. This manifests itself in the form of whims and scandals with parents regarding the food being taken, pastime, going to bed and place of stay. The child has not yet learned how to compare his desires with reality, but he already has the opportunity to achieve his own goal independently - to go to a candy vase, get out of bed and sleep in a chair, and so on.
The desire to explore the world is a leading need in this age, so attempts to touch a hot stove or put your fingers in the socket are completely organic for a child and cause horror to parents. At the junction of internal desire and external prohibitions conflict is born, and as a result - scandals.
