Does your child not share toys, demand expensive gadgets and slam the door when you ask for help?
Congratulations: you are on the home stretch to your goal of growing an egoist.
Modern parents are so afraid of “traumatizing” their children that they imperceptibly turn them into little tyrants.

Here are the daily rituals that are guaranteed to destroy empathy and instill the thought: “The whole world should revolve around me.”
You always put his interests above your own.
You cancel a meeting with a friend because "your daughter wants to go to the movies." You eat a cold dinner while your son chooses what he wants.
Each such victim is a brick in the wall of childish egoism.
Psychologists warn: “A child who does not see that parents have their own needs grows up to be an emotional invalid.”
You justify every action he takes.
“But he’s a child!” you say when he’s rude to his grandmother or breaks someone else’s thing.
But children are not aliens. They only learn consequences if they see boundaries.
In the family of a Moscow teacher, they practice the rule: "Apologize and fix it." If the son spills juice, he wipes it up; if he is rude, he suggests a way to make amends.
Selfishness is not an innate trait, but a result of your fear of saying "no". Change the rules before your child starts dictating them to you.
