When a mom holds her preemie skin-to-skin, their brain waves actually start syncing up in real-time.

The Takeaway
Using dual-head EEG caps, researchers discovered that during 'Kangaroo Mother Care,' the electrical rhythms of a mother's and infant's brains align across multiple frequencies. This neural connection isn't just a byproduct of calming down; it directly correlates with more efficient development of the baby's internal brain networks.
From the abstract
Kangaroo mother care (KMC) is an intervention involving skin-to-skin contact that promotes physiological stability and supports long-term neurodevelopment in preterm infants. However, the underlying neurophysiological mechanisms remain unclear. We aimed to investigate the immediate effects of the first KMC on infants' brain function, mother-infant inter-brain synchrony, as well as their associations. Fifty-eight preterm infants (gestational age < 32 weeks or birth weight < 1500 g) and their moth
