Problem
Every child has the right to education, health and protection yet, millions of children worldwide are denied a fair chance [1,2]. Many children are not enrolled in primary education, they miss critical development opportunities that affect the rest of their lives [2]. Children are also at a higher risk of getting and dying from preventable diseases, with problems exacerbated by malnutrition and lack of water and sanitation [3,5]. Around one billion children each year experience a form of emotional, physical or sexual violence that causes long-term or permanent damage [2,4].
