, early childhood also includes infancy. At this stage children are learning through observing, experimenting and communicating with others. Adults supervise and support the development process of the child, which then will lead to the child's autonomy.

They are at a stage where they make new friends and gain new skills, which will enable them to become more independent and enhance their individuality. During middle childhood, children enter the school years, where they are presented with a different setting than they are used to. This new setting creates new challenges and faces for children. Upon the entrance of school, mental disorders that would normally not be noticed come to light. Many of these disorders include:

Middle childhood is the time when children begin to understand responsibility and are beginning to be shaped by their peers and parents.
