Explanation: Given that Dimitri is three years old, he is in the preoperational stage of cognitive development when he is unable to grasp other people's perspectives and positions, Dimitri can only grasp things on a symbolic level. So Dimitri cannot put himself in the position of his friends and see what they feel when he almost doesn't cares and takes their toys. That is why his mother's words do not affect him, because his mother alludes to Dimitri imagining what other children feel when their toys are stolen. Maybe instead it would be better for his mother to take his toys from Dimitri and then he will understand what it looks like because he will personally experience that feeling. And that should be done with the words that his toys are being taken because he is not behaving, and that he will return to him when he starts behaving appropriately. This would be a lower level, which should be gradually upgraded and begin to teach him that in addition to getting toys back when he starts behaving appropriately, he should also share his toys with others and not take toys away from others without asking.
