Lifegiver-self

The first of the six circles and the one nobody chooses. An infant is born into a lifegiver-self, which is already in place rather than assembled after birth, since the shared animus between mother and infant is the earliest version of an interaction self and forms during pregnancy and birth rather than after them. That is why the definition names a shared animus and a cluster of interactions rather than a relationship, since a single pooled animus held by two people is a different thing from two selves in contact. The necessity is structural rather than sentimental. An infant cannot define a membrane around solely their own body, since a body that young is in no way autonomous, and attempting it would produce overwhelming existential threat. The first membrane therefore has to enclose someone else, and the lifegiver is who it encloses. Everything arriving before birth belongs to this circle too, since the self has already been affected by every hormonal reaction during pregnancy, all history carried in the DNA, traces from earlier children and sexual partners, parasites and other body co-occupiers and environmental pollutants and stressors. The caregiver-self is established immediately afterwards and is a separate circle, which is why Marsh keeps lifegiver and caregiver apart as terms. Nothing is outgrown, so the lifegiver-self remains part of a healthy person for life rather than being superseded.

Attachment theory after Bowlby made the infant's first bond the foundation of later relationships, and object relations theory, particularly Winnicott's claim that there is no such thing as a baby without a mother, comes very close to Marsh's structural point. Margaret Mahler described separation-individuation as a developmental achievement. Foetal programming research documents prenatal influence on later development. Marsh's version differs by refusing the developmental framing, since for Mahler the merged state is something to be worked out of and for Marsh it is a circle that accumulates rather than a stage that resolves, so nothing about maturity involves leaving it behind.
