Many Researchers had made a wide research on Child Psychology. Among those,Sigmund Freud has developed a new theory in the Child development.Freud believed that the way parents dealt with their child’s basic sexual and aggressive desires would determine how the child’s personality developed. Freud also thought that all babies were born with instinctive selfish urges which he labeled the “Id”. As a child experienced that not all his or her whims were met, he or she developed a more realistic appreciation of what is realistic and possible, which Freud called the “Ego”. Over time, Freud believed, babies learn values or morals, which he called the “Super-Ego”. The Super Ego, he thought, then worked with the Ego to control the selfish urges of the Id.
