Answer: Single parent
Explanation: A family consisting of only one parent and children under 18 is considered a single parent family. Since these are children under 18, and in this case the child is eight months old, then it is clear that the head of the family is the parent, who cares for the child. Single is due to, for example, a divorce, or widowhood, or simply a parent not married and having a child, or or the child is adopted by one person. In each case such family is managed by only one parent. Given that the woman's father lives close but in a nursing home, it is not also an extended family, which is when one, the father or the mother (or both) of one of the parents lives in the family.
