Oedipus period
Psychoanalysis believes that children aged 3-6 will enter Oedipus, that is, boys will want to compete with their fathers for their mothers, and girls will want to compete with their mothers for their fathers. Oedipus competition is the beginning for children to show their life strength to the outside world. When children can handle the relationship between competition and cooperation with their parents, their hearts will gradually become tough, their individuality will gradually form, and they will have a good psychological foundation when they participate in more complicated, more real and fierce social competition.
