Why does the narrator send the postcard to her mother saying, "I found my head rights, Mama. They're coming with me"? What might this remark foreshadow?

At first she does not know what to do with the child, but immediately after seeing proof of sexual abuse, Taylor writes her mother to say that her “head rights . . . [are] coming with [her],” implying that she now sees the child as an inalienable part of her. This foreshadows Taylor's intrepid motivation to become the child's mother.
