Understanding child behavior emotions and thoughts is called child psychology. The study of child psychology helps to understand behavior, nationality, age, career, health, and more. It helps an individual to learn important information. It is helpful to provide the best for every child. Each child is different with their own wants and special needs. Child psychology revolves around children and their behaviors, emotions and thoughts. From recent few years, child psychology has been a better understood subject. The present rate of juvenile crime and delinquency might not have reached such alarming proportions. It is the feelings about and reactions to the inputs during childhood that formulate a youth’s policies and beliefs for future life. According to a study, psychological problems that crop up in childhood can translate into serious consequences like criminality later on & also unresolved psychological complications can result in an unhappy and traumatized adulthood. These are some of the potholes along the highway of modern life that child psychologists help to fill. In childhood, continuous changes occur. There are numerous issues that a child encounters as they progress through their childhood, pre-teen years, and into adolescence. At early age of childhood, a child should be given as much love and attention as possible, to allow it to develop physically, mentally and emotionally. The children should be taught how to eat, walk and talk and how to get the most out of what it learns at school and college. When a child joins his first school, he will have that feeling of lack of self esteem. He or she is not that open to meeting new people at a sudden time. He might feel really down and stressed at first. It will take time depending on the child how quick he can adopt such situation. Children are also being afraid of their dreams which they do not understand. If a child had a dream which terrifies him too much, he will then be afraid to go to sleep knowing he might dream of that again. Hence they should be treated carefully. We need to take care of our children not only with his physical and educational needs but as well as his psychological need. Understanding psychological need is necessary for proper child’s growth.
