Craniopagus.

An extended case study of craniopagus, twin baby girls who were born conjoined at the cranium (head). The case study observes them soon after birth and at various points until toddlerdom after they are separated at just over one year old. Thereafter only only of the twins are seen so the assumption must be that only one survived. Some developmental stages are illustrated by various developmental tests before one of the children is seen playing in a garden.
