A child (pl. children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty. The term may also refer to an unborn human being. In English-speaking countries, the legal definition of child generally refers to a minor, in this case as a person younger than the local age of majority (there are exceptions like, for example, the consume and purchase of alcoholic beverage even after said age of majority), regardless of their physical, mental and sexual development as biological adults. Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions.
