Just like physical development, girls' psychological changes will vary according to the situation and personality. In order to better understand, psychologists divide puberty into two stages based on the onset of menstruation: pre-puberty before menstruation and adolescence after menstruation.
This is the end of childhood and the necessary stage of shaping a new personality, a new "I". When children are close to 3 years old, they also have a similar period, that is, the age of "no". At that time, they have to come by themselves, "do it alone", see what, move what. That was their first independent action to get rid of the passive baby world. Also in this period, "I" appeared in the language. The second independent consciousness occurred in the present pre-adolescence. We must start fighting again to prove our existence. In this "adolescence" crisis, girls are dominated by nature. The consciousness of sexual instinct is weak, which is the last stage of the incubation period.
All the energy of girls is focused on building strong "self". The unexpected development of the body has destroyed the image of girls, and girls can no longer be regarded as "children" at will. They want to break through the shackles and cry out to break free from the prohibitions, rules and orders that still restrict their daily life. They became no longer submissive. This is a difficult time for the family. The family is exhausted by the little princess who is "hard to serve", who has conflicting ideas and often has some problems that are difficult to fight. However, it is in this way of resisting the family that girls learn to affirm themselves. (However, this is just a struggle, and family is still indispensable to them.) Psychologists suggest that we face up to conflicts and avoid two extremes: unconditionally quelling conflicts or forcefully suppressing conflict.
Pre-adolescent children are very active, constructive and aggressive. Unfortunately, these new energies are not always dredged according to parents' expectations. Learning becomes erratic, irregular and poor. On the contrary, heckling and truancy frequently occur. Girls in this period like to do everything except those imposed on her.
