What are the signs of childhood depression?

Signs include persistent sadness lasting more than two weeks, withdrawal from friends and activities they used to enjoy, changes in sleep or appetite, frequent complaints of stomachaches or headaches, declining school performance, and expressions of worthlessness or hopelessness. Depression in children can look different from adult depression — irritability is often more prominent than sadness. If you notice these signs, seek an evaluation from your pediatrician or a child mental health professional.
