What is Relactation?

Relactation is the process of rebuilding milk supply after it has decreased or stopped. Breast milk supply typically "dries up" within 2–3 weeks postpartum if breastfeeding is never initiated after birth. If breastfeeding or pumping continues for a longer period of time, it may take many months for milk production to fully decrease after weaning.

The process of relactation can begin weeks, months, or even years after breastfeeding has stopped, and the experience looks different for everyone. Some mothers are able to rebuild a full supply, while others produce smaller amounts of milk that still support their baby's health and meet their feeding goals. This process often requires time, patience, strong support, and realistic expectations.

Many mothers begin relactation hoping to practice exclusive breastfeeding—where all infant feedings come directly from the breast—while others combine breastfeeding, pumping, and bottle feeding. It’s okay to begin without knowing exactly what your feeding journey will look like in the long term. Even partial relactation can be meaningful, and any amount of breast milk, along with time at the breast, can support both nourishment and connection between mother and baby.

In recent years, concerns around baby formula shortages have led to a significant increase in interest in relactation as families look for ways to help ensure their babies receive enough breast milk. For many mothers, relactation is not only about milk production, but also about rebuilding the nursing relationship and closeness with their baby.

Other reasons mothers choose relactation:

• A baby developing a severe formula intolerance, such as a cow’s milk protein allergy, and needing human milk

• Reunification after a long period of separation, such as an extended neonatal intensive care unit (NICU) or maternal hospital admission

• Families growing through adoption or surrogacy

• A previous medication or treatment that was not compatible with breastfeeding

• Difficulty accessing clean water for formula preparation during emergencies or natural disasters

Before beginning relactation, it’s important to have a good support system in place. Relactation often takes a lot of time, effort, and emotional energy, and having encouragement from your partner, family members, friends, coworkers, and healthcare providers can make the process feel more manageable.

Working with a lactation specialist—such as an IBCLC (International Board Certified Lactation Consultant) or breastfeeding medicine physician—can be especially helpful during this time. You may find it useful to connect with a few different providers until you find someone who feels like a good fit for your family, communication style, and feeding goals.

Peer and community support can also make a meaningful difference. Breastfeeding support groups and organizations such as La Leche League can offer encouragement, practical tips, and reassurance throughout your relactation journey.

Our bodies release prolactin and oxytocin—the main hormones involved in milk production and release—in response to nipple and breast stimulation.

Relactation typically requires frequent nipple stimulation and milk removal through breastfeeding, pumping, hand expression, or a combination of all three. Most mothers are encouraged to stimulate and empty their breasts at least 8 times in each 24-hour period. Because prolactin levels are often highest at night, at least one overnight pumping or breastfeeding session is recommended.

At first, you may only notice a few drops of milk, but even small amounts are a positive sign that your body is responding. While rebuilding your supply can sometimes feel slow, consistency is often one of the most important steps in relactation success. Over time, frequent milk removal helps support the release of prolactin and encourages ongoing production.

Hand expression can be an excellent way to remove additional milk after pumping or breastfeeding. Some mothers also use it between sessions for extra stimulation throughout the day.

Because hand expression requires no special equipment, it can be done almost anywhere and may be easier to fit into busy moments with your baby. Gentle breast massage while pumping, breastfeeding, or hand expressing may also support milk flow and more complete breast emptying. Even small increases in output can be a reassuring sign that your body is responding to stimulation and working toward increasing supply.

Even if you are exclusively pumping, holding your baby close and offering time near the breast may help support relactation and rebuild your nursing relationship. It is very common for babies to need time before feeling comfortable latching again after bottle feeding or time away from the breast. Because of this, many mothers find it helpful to focus first on skin-to-skin contact during the first week or two of relactation, without pressure or expectations around latching.

Skin-to-skin involves holding your baby against your bare chest while your baby wears only a diaper. This can help your baby feel calm, secure, and connected while supporting natural feeding instincts. Some babies may even move toward the breast and latch during this time.

For mothers, skin-to-skin can also be deeply supportive. It can encourage the release of prolactin and oxytocin, support milk production, and strengthen confidence and bonding during a time that may otherwise feel uncertain.

For many mothers—especially those experiencing low milk supply—small adjustments to pumping strategy can make a meaningful difference during relactation. Frequent pumping is often a key element in rebuilding milk production, particularly in the early stages or when baby is not yet transferring enough milk at the breast.

A high-quality double electric breast pump designed for regular, long-term use is usually most effective. These pumps support consistent stimulation and more complete milk removal than wearable or battery-powered pumps. That said, wearable pumps can still play a supportive role. While not typically recommended as a primary pump for relactation, they can make frequent pumping more manageable and serve as a helpful backup when you are on the go or need more flexibility throughout the day.

Some mothers may also benefit from renting a hospital-grade breast pump during relactation. These pumps are designed to establish and maintain milk supply and often provide stronger, more customizable suction patterns. Using a pumping bra while double pumping can also make sessions feel more efficient and manageable.

Power pumping is a strategy designed to mimic cluster feeding and provide additional breast stimulation over a shorter period of time. This typically involves pumping on and off over the course of about an hour.

Some mothers find that adding one or two power pumping sessions per day helps support more complete breast emptying, increased stimulation, and greater milk output. While it can be helpful, regular and consistent milk removal remains the most important factor in building supply.

Once your baby feels comfortable near the breast, latching attempts can begin gradually. During this stage, pumping will likely continue to be the main way to stimulate your production between feeds.

Babies often latch more easily when they are calm and not overly hungry. Offering a small supplemental feeding by bottle or cup before attempting to latch can sometimes help reduce frustration. Offering your breast for comfort outside of feeding times can also be a gentle way to encourage familiarity and help your baby reconnect with breastfeeding in a low-pressure way.

The transition from bottle feeding to direct breastfeeding is often a gradual process. Supplementation may still be needed for a period of time to support your baby’s needs while your supply increases. Some families may choose to supplement with formula, expressed breast milk, or donor milk during this process.

Some families find that certain feeding tools can help ease the transition from bottle feeding back to the breast.

Nipple shields are thin, flexible silicone covers placed over the nipple during breastfeeding. For some babies, this can feel more familiar or bottle-like, which can ease the transition back to the breast. Nipple shields may make latching easier while babies are learning and they can be used as a temporary bridge while feeding skills improve, with the goal of transitioning to direct breastfeeding.

A supplemental nursing system (SNS) allows babies to receive supplemental milk through a thin tube while breastfeeding. This can be especially helpful when babies need additional volume or while milk supply is still increasing. The SNS helps support the breastfeeding relationship, even when full milk transfer is not yet established.

In some cases, these helpful tools may be used together as part of a step-by-step transition from bottle or cup feeding toward full breastfeeding.

During relactation, it’s important to ensure babies continue receiving adequate nutrition and gaining weight appropriately. The American Academy of Pediatrics recommends close monitoring of infant growth when there are concerns about milk intake or weight gain.

Regular weight checks, monitoring diaper output, and communication with your baby’s pediatrician can all help ensure your baby’s needs are being met while your milk supply is growing. Some families choose to rent or purchase a baby scale to monitor weight gain at home for additional reassurance. Your pediatrician and lactation consultant can also help guide supplementation plans, if needed.

Some mothers may notice small amounts of milk within a short time—sometimes within the first week or two with frequent stimulation. For others, it may take a longer time before changes are noticeable. Every journey is different, and gradual progress is still meaningful.

Relactation often unfolds over many weeks or months, and the pace can vary widely depending on individual factors. In general, relactation may be more straightforward when the baby is younger and there has been a shorter gap since breastfeeding. However, even after a long period without breastfeeding, relactation may still be possible.

Most women will produce at least some breast milk with frequent breast stimulation and adequate support. However, not all mothers regain a full milk supply. Some continue supplementing for the long haul while providing some breast milk or maintaining a breastfeeding relationship and connection with their baby.

Frequent milk removal and breast stimulation remain the foundation of relactation. However, additional strategies may sometimes help support milk production along the way.

Galactagogues—herbs or medications used to support milk supply—are sometimes recommended during relactation. Common herbal galactagogues include fenugreek, fennel, milk thistle, goat’s rue, shatavari, moringa, and others. The main prescription medications sometimes used under medical supervision include Metoclopramide (Reglan) and Domperidone. Because these medications can have side effects and are not appropriate for everyone, they should only be used with guidance from a qualified healthcare provider.

Along with breast stimulation, supporting your body’s needs can also play an important role in increasing supply. Eating enough calories and staying well hydrated help provide the energy needed for frequent feeding, pumping, and milk production.

Rest is another important factor, even though it's not always easy. Sleep deprivation and exhaustion can make relactation feel more physically and emotionally challenging. Accepting help when possible and prioritizing opportunities for rest—even short periods throughout the day—can support both emotional wellbeing and the overall relactation process.

Several factors can influence relactation success:

• Your baby’s age

• Time since weaning

• Frequency of pumping or breastfeeding

• Access to support

• Realistic expectations

Managing stress is also important. Prioritizing self care—rest, hydration, nourishment, and emotional support—is especially important. Relactation can be both physically and emotionally demanding. Having compassionate support and flexibility throughout the process can make a meaningful difference for both you and your baby.

Relactation is rarely a linear process, and there is no single “right” way for it to unfold. Some days may feel encouraging, while others may feel slow or uncertain. Both are part of the process. With time, support, and care for your own wellbeing, many mothers find that even partial relactation brings meaningful connection, comfort, and confidence in feeding their baby.
