Maternal mindfulness during pregnancy predicts newborn neurobehavior.

Newborn neurobehavioral competencies portend a young child's abilities to modulate their arousal and attention in response to dynamic environmental cues. Although evidence suggests prenatal contributions to newborn neurobehavioral differences, no study to date has examined wellness-promoting traits, such as a pregnant woman's mindfulness, in this association. We examined whether a mother's mindfulness while pregnant related to neurobehavioral outcomes in her neonate, as well as whether maternal mindfulness moderated the link between prenatal maternal emotion dysregulation and newborn neurobehavior. Mothers (N = 162) reported on their mindfulness and emotion dysregulation while pregnant. Newborn arousal and attention were assessed at least 24 h after birth (M = 3.8 days, SD = 8.3) using the NICU Network Neurobehavioral Scale (NNNS). Highly mindful pregnant women reported lower levels of emotion dysregulation. Newborns of highly mindful mothers exhibited higher levels of arousal (e.g., excitability, motor activity) but did not differ in regards to attention at birth. Maternal emotion dysregulation while pregnant was associated with blunted newborn attention, but only among mothers who were less mindful. Our findings suggest that a mother's mindfulness while pregnant may influence her fetus' neurobehavioral development in ways that are evident at birth.
