Researchers at Radboud University and the Radboudumc found that mothers with postpartum depression benefit from oxytocin nasal spray. The oxytocin causes mothers to respond more positively to their newborn child. "Although extra oxytocin does not affect mothers' caregiving behavior and stress levels, it does contribute to better contact between mother and child," according to psychologist Madelon Hendricx-Riem, one of the researchers.
