Fact of the Day: oxytocin and the milk ejection reflex

There two important hormones for breast milk production: oxytocin, which is your cuddle hormone, and prolactin, which is your milk maker. During suckling, milk ejection, or “let down”, occurs when oxytocin released into the circulation reaches the mammary glands. Maternal oxytocin is not only released into the circulation by suckling and skin-to-skin contact, but may be released when the mother sees and hears her newborn or simply thinks of him or her. Oxytocin release can even be conditioned to other stimuli, meaning your milk ejection reflex may occur even in the absence of suckling (Tancin, Kraetzl, Schams, & Bruckmaier, 2001). If you’re a Pumping mom this is important to grasp. Try building a routine with your baby during breastfeeding that you can carry over into pumping. Maybe it’s a song you listen to, a smell like lavender or vanilla, or holding a particular blanket. By bringing this into the pump room you can help stimulate oxytocin to help with let down.
