The parenting style most encouraged in modern America is Permissive. This parenting style requires that parents should be loving, giving children the freedom to make their own choice as much as possible. Permissive parents have few rules and do not stand over children like an authority figure. Authoritative is the opposite of permissive and here parents make rules and children have little say in making choices about themselves.
