Child corporal punishment lawsThe legality of corporal punishment of children varies by country. Corporal punishment of minor children by parents or adult guardians, which is intended to cause physical pain, has been traditionally legal in nearly all countries unless explicitly outlawed. According to a 2014 estimate by Human Rights Watch, "Ninety percent of the world's children live in countries where corporal punishment and other physical violence against children is still legal".
Childhood traumaChildhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances.
