Mental health in childhood includes reaching developmental and emotional milestones, as well as learning healthy social skills and how to cope when there are problems. 

Mental health disorders in children and adolescents are described as serious changes in the way children typically learn, behave, or handle their emotions, causing distress and problems getting through the day. It is estimated that approximately 30% of school aged children will experience a behavioral, mental, or developmental condition in any given year.
