A child is the son or daughter in relation to the father or mother. The father is bound to maintain his children and to educate them, and to protect them from injuries. Children are, on their part, bound to maintain their fathers and mothers when in need, and they are of ability so to do. The father in general is entitled to the custody of minor children, but under certain circumstances the mother will be entitled to them when the father and mother have separated.
Children are liable to the reasonable correction of their parents.
When legally construed, the term children is confined to legitimate children. Posthumous children are those who are born after the death of their fathers. In Pennsylvania, the will of their fathers in which no provision is made for them is revoked, as far as regards them, by operation of law.
