Hypothesized impacts of dyadic synchrony formation on autonomic outputs in mothers and infants.

Physiologic or Pathologic Change in Early Parenthood	Temperature	HR	HRV	Emotional State
Skin-to-skin contact and family nurturing	decrease; oscillation with breast-feeding	Lower [247]; synchronized oscillation with breast-feeding	elevate [248]; synchronized oscillation with breast feeding	fatigue, relaxation, bonding, love
Early postpartum maternal-infant separation, formula use, short maternity leave	attenuated decrease, reduced synchrony of oscillation	attenuated decrease, reduced synchrony of oscillation	attenuated elevation, reduced synchrony of oscillation	fatigue, stress, attenuated bonding
Development of healthy dyadic synchrony	appropriate oscillatory synchrony	appropriate oscillatory synchrony	appropriate oscillatory synchrony	fatigue, stress, relaxation, bonding, love
Postpartum depression	circadian destabilization, reduced amplitude, decreased oscillatory synchrony	elevate	decrease	depressive symptom onset
