Who is referred to as the person with whom the child resides?

The term "custodian" specifically refers to an individual who has physical custody of a child, meaning that this person is responsible for the child’s day-to-day care and living arrangements. In many legal and social contexts, the custodian is considered the person with whom the child resides on a regular basis, which is essential for matters relating to guardianship, custody arrangements, and welfare assessments.

In contrast, a guardian may have legal authority over a child but does not necessarily reside with them. A parolee is someone who has been released from prison under specific conditions, and a defendant refers to an individual accused of a crime in a court of law. These roles do not pertain directly to the living arrangements concerning children. Hence, the definition and legal implications surrounding the term "custodian" make it the most accurate answer to identify the person with whom the child resides.
