A child is an actual human being, with a capability to reason, and thus a child in principle has the same right to life as an adult.
However, the application of this right for a young child differs in practice from that of an adult, as a child’s conceptual faculty is not fully developed, i.e., a six-year-old does not have the right to choose to enter a sexual relationship, whereas an adult does.
A parent as a child’s legal guardian is responsible for the child until they formerly revoke guardianship, and/or the child is considered an adult. Guardians are individuals who make decisions for the child—in the child’s best interest—until the child’s mind is developed enough so that the child can make decisions for himself.
If a parent gives birth to a child—and claims to be its guardian (which is the prerogative of the parent)—then that parent is responsible for taking care of the child, unless the parent revokes guardianship, and turns the child over to someone else for adoption. (A parent that gives birth to a child, claims to be its guardian, and leaves the child in a trash bin has attempted murder.)
