Children generally have fewer rights than adults and are classed as unable to make serious decisions, and legally must always be under the care of a responsible adult. Recognition of childhood as a state different from adulthood began to emerge in the 16th and 17th centuries. Society began to relate to the child not as a miniature adult but as a person of a lower level of maturity needing adult protection, love and nurturing. This change can be traced in paintings: In the Middle Ages, children were portrayed in art as miniature adults with no childish characteristics. In the 16th century, images of children began to acquire a distinct childish appearance. From the late 17th century onwards, children were shown playing. Toys and literature for children also began to develop at this time.[7]
