It's definitely impossible for a child around the age of three to let her have regular friends. Because three years old is a stage with strong self-awareness, none of them want to communicate with their peers actively, so it is very normal for children to have a friend today and a friend tomorrow, because children in this period can't make friends yet and need the guidance of adults. In addition, as early childhood educators, we don't want children to play games with the same child every day, because it may lead to children's loneliness and insecurity, so we can always find a good friend. Of course, we still hope that children can always find some good friends when they feel insecure, but after a long time, we still hope that children will have more friends, which can effectively promote their interpersonal skills. So parents don't have to worry, try to encourage their children to make more friends and expand their social circle!
