Relactation is the process of restarting milk production after the supply has stopped completely or significantly diminished. This is possible for many mothers who wish to resume nursing after a break due to illness, separation, or a previous decision to stop. Relactation is often achievable, demonstrating the body’s adaptive capabilities. This guide covers the physiological mechanisms, practical steps, and support options for successfully restarting your milk supply.
The Biological Possibility of Relactation
The mammary glands retain the ability to produce milk long after they have stopped or “dried up,” because the underlying cellular machinery remains intact. Milk production is primarily controlled by two hormones: prolactin, which signals the cells to synthesize milk components, and oxytocin, which triggers the milk ejection reflex, often called the let-down. Restarting the supply, therefore, involves signaling the brain to re-elevate the levels of these hormones through frequent physical stimulation.
The most potent stimulator of prolactin synthesis is mechanical stimulation of the nipple, such as from suckling or pumping. This stimulation signals the pituitary gland, promoting prolactin release. Oxytocin is also released in response to stimulation, but it is sensitive to environmental cues like hearing a baby cry or skin-to-skin contact, which help initiate the milk flow. Consistently providing this mechanical and sensory input reactivates the production cycle.
Practical Methods for Stimulating Milk Production
Relactation relies on the principle of supply and demand; frequent and effective milk removal is the most important stimulus. To maximize hormone levels, stimulate the breasts at least eight to twelve times within a 24-hour period. Each session, whether pumping or nursing, should last 15 to 20 minutes. Consistency is key, so avoid going more than a few hours without stimulation, including at least one session overnight.
Using a high-quality, double electric breast pump is recommended because it allows simultaneous stimulation. Double pumping is more efficient and results in higher prolactin levels compared to pumping each side individually. A hospital-grade pump, often available for rent, offers the best suction strength and cycling patterns to signal the body effectively.
Integrating hands-on techniques with the pump maximizes milk removal and signaling. Gentle breast massage before and during pumping encourages milk flow and drainage. Applying breast compressions while pumping helps fully empty the milk ducts, signaling the body to produce more milk. Even if the pump yields only drops, this frequent stimulation builds the foundation for future supply.
Skin-to-skin contact with the baby is a powerful non-mechanical method to enhance the process. This physical closeness promotes oxytocin release, which facilitates the let-down reflex and supports the hormonal environment for lactation. Offering the breast often, even for comfort, reinforces the baby’s association with the breast and provides effective natural stimulation. Alternative feeding methods, such as a Supplemental Nursing System (SNS) at the breast, can encourage the baby to latch by ensuring they receive nutrition while stimulating the supply.
Factors Influencing Relactation Success
Relactation success is highly individualized and influenced by several variables. A significant factor is the duration since the mother last breastfed; the shorter the time gap, the quicker the supply can return. Mothers who had a robust milk supply prior to weaning often have a better starting point compared to those who struggled with supply initially.
The age and cooperation of the infant also play a substantial role in the success rate. Younger infants are often more willing to latch onto the breast and have a stronger, instinctive suckling reflex, which provides superior stimulation. It can become more challenging to encourage a baby to latch effectively after six months of age, particularly if they have become accustomed to bottle feeding. A mother’s general health, stress levels, and existing medical conditions can also impact the body’s ability to respond to the stimulation protocol.
Setting realistic expectations is paramount, as relactation can be a time-consuming commitment that requires patience. Success is not solely defined by achieving a full milk supply, as producing any amount of breast milk can be beneficial for the infant. Many mothers successfully achieve partial lactation, which still allows them to combine nursing with necessary supplementation.
Medical and Non-Medical Support Options
External aids, often called galactagogues, can support relactation when non-pharmacological methods are insufficient. These substances target the hormones involved to help increase milk production. However, these aids are ineffective without concurrent, frequent milk removal.
Pharmaceutical options, such as the prescription drug domperidone, function as dopamine antagonists that increase prolactin secretion. Domperidone has been shown effective in increasing milk production, though its use for lactation is often “off-label” and requires medical supervision due to potential side effects. Metoclopramide operates similarly but has shown mixed results regarding its effectiveness.
Herbal and supplemental galactagogues, such as fenugreek, blessed thistle, and goat’s rue, are widely used. However, the scientific evidence supporting their efficacy is often limited and mixed. The lack of standardized doses and high-quality clinical trials means their effect on milk volume is uncertain. Any use of supplements or medications should be discussed with a healthcare provider to ensure safety.
Professional guidance is an invaluable resource throughout the relactation process. Consulting with an International Board Certified Lactation Consultant (IBCLC) provides personalized support, including troubleshooting latch difficulties and developing a structured pumping schedule. An IBCLC can also assess the infant’s milk intake and weight gain to ensure the baby receives adequate nutrition while the mother’s supply is building.
