Following the steps listed below, most moms notice an increase in supply within 24-72 hours. Time your feedings from the beginning of one to the beginning of another. Allow the baby to nurse on each side until he pulls off himself or goes to sleep. Offer both breasts at each feeding. Double pumping has been shown to increase Prolactin levels.
Prolactin is the hormone which stimulates milk production.
Pump for 10-15 minutes per session. Longer sessions have not been proven to be any more beneficial at increasing supply. Along with nursing, you may want to add another pumping session or two sometime during your day. Allow the baby to meet all of his sucking needs at the breast. Avoid any bottles or pacifiers during this time.
