Developmentally, children and adults think about friendships differently. Even after seeing you at your worst, she still likes you. Children take another perspective. As they grow in age and understanding, they eventually develop an adult concept of a friend, but this typically does not happen until mid-adolescence. It is important to remember that a child's idea of a friend differs from an adult's.
Preschoolers choose friends based on who they see regularly.
Friends share toys and play games. If there is a fight or a friend moves away, the friendship ends. School-aged children select friends who help them. They select friends who have similar interests and enjoy doing the same things. They recognize that friends share thoughts and feelings.
