(a) The duty to support a child under the age of 18 years, whether born in or out of wedlock, rests primarily upon the child's parents.
(b) Where the parents are unable to provide a minor child's minimum needs, a stepparent or a person who cohabits in the relationship of husband and wife with the parent of a minor child shall be under a duty to provide those needs. Such duty shall exist only while the child makes residence with such stepparent or person and the marriage or cohabitation continues.
(c) The duty to support a child under 18 years of age, whether born in or out of wedlock, shall rest equally upon both parents.
