Responsive caregiving is the biological baseline for an infant’s stress system.

Evidence

The infant’s HPA axis is not designed to operate in isolation. It is designed to be co-regulated by a caregiver. The responsiveness of the caregiver is built into the normal operation of the infant’s stress system. This is not a welfare enhancement; it is the biological baseline. An infant whose caregiver is absent or unresponsive is not experiencing a deficit relative to a normal operating state. The absent caregiver is the abnormal condition. The present, responsive caregiver is what the biology expects and requires. — , The Rod and the Child, 9707
