Verified step by step guidance

Identify the physiological process involved: The 'letdown' reflex is a physiological response that occurs in lactating mothers, facilitating the release of milk from the mammary glands.

Understand the role of hormones in this process: Hormones are chemical messengers that regulate various bodily functions, including lactation.

Review the function of each hormone listed: Insulin regulates blood sugar levels, Cortisol is involved in stress response, and Melatonin regulates sleep-wake cycles.

Focus on Oxytocin: Oxytocin is a hormone that plays a crucial role in childbirth and lactation. It stimulates the contraction of the milk ducts, aiding in the milk 'letdown' reflex.
