what hormone is necessary for the let-down reflex?
Oxytocin is another one of the important breastfeeding hormones. The production of Oxytocin is also caused by an infantâs suckling, but instead of making milk, it is responsible for the milk ejection reflex, also known as the âlet down.â The milk ejection reflex works as a reward for all of the babyâs hard work.
Oxytocin and Prolactin are the hormones produced during breastfeeding that work together to make milk, establish a letdown, and keep up with the supply and demand of a nursing infant.
