Trajectories of changes in oxytocin and vasopressin before, during, and after mother-infant interaction: a descriptive study of mothers and infants affected by postpartum depression

Our findings illustrate trajectories of the mother's and infant's OT and VP before, during, and after interactions, and alterations of these trajectories in the presence of PPD. The findings add valuable data to the field's understanding of how the OT and VP systems function in healthy postpartum mothers and infants and how they become dysregulated in the presence of PPD.
