3 ~ 6 years old is the "Oedipus period", and it is best to separate beds and rooms before 3 years old. Parents can creatively answer questions related to sex.
Sometimes it's not that the child can't be independent, but that the mother herself has separation anxiety. The biggest influence on children is not necessarily the housing distribution itself, but the family relationship model. The sensitive period of coping with Oedipus emotion is between 1 ~ 3 years old, and the child has experienced some key events, such as weaning and defecation training.
At this stage, children begin to distinguish themselves from their appearance, resulting in a sense of independence and control. Children have the ability to be independent from the outside world, and this stage is suitable for separate beds and rooms.
Psychoanalysis believes that the age of 3 ~ 6 is the "Oedipus period" of children, and children will be more sensitive to the relationship between parents and the problems between the sexes. From the perspective of sexual psychology, it is best for children to be separated from their parents after the age of 3, at least it is impossible to directly see the gender of their parents.
