Breast Milk Leaking: Here’s What You Need To Do

Posted on 1/06/2024 in Motherhood

Breastfeeding is a beautiful journey filled with numerous benefits (and challenges) for both mother and baby. One common challenge that many new mamas face is breast milk leakage. While it can be embarrassing and messy, it's important to remember that it's a completely normal part of the breastfeeding experience, happening to around 70% of breastfeeding women. Here's a guide to understanding and managing breast milk leakage with confidence and ease.

Why Do Breasts Leak Milk?

Breast milk leakage can occur due to various factors, including hormonal influences, anatomical factors, and behavioural triggers.

Hormonal Influences

  • Oxytocin: This hormone triggers milk let-down and can cause some leakage, especially before a baby latches. Studies like this one from 2015 highlight how oxytocin sensitivity varies among individuals, influencing letdown intensity and potentially contributing to leaks for some women.
  • Prolactin: Responsible for milk production, elevated prolactin levels can lead to oversupply, increasing the risk of leaks. Research like this 2008 study explores the complex interaction between prolactin and oxytocin regulation during breastfeeding.

Anatomical Factors

  • Nipple sensitivity: Sensitive nipples can trigger let-down easily, causing leaks at even slight stimulation. A 2022 study suggests some women have genetic variations affecting nipple sensitivity, potentially contributing to this experience.
  • Milk storage capacity: Breasts with smaller milk storage capacity may experience overflow and leaks sooner than those with larger capacity. This 2016 study explores breast anatomy and milk storage variations among women.

Behavioural Factors

  • Feeding frequency and duration: Skipping feeds or having shorter feeds can lead to milk build-up and eventual leaks. Studies like this 2014 one investigate the optimal feeding frequency for infants and highlight the impact on milk supply and potential leaking issues.
  • Stress and emotional responses: Emotional triggers can stimulate oxytocin release, leading to let-down and potential leaks. A 2013 study explores the impact of stress and emotions on hormonal responses during breastfeeding.



What Triggers Milk Leakage?

Breast milk leakage can be triggered by emotional and physical stimuli. Here are some common triggers:

Emotional Triggers

  • Seeing or hearing a baby cry: This is a strong trigger for the release of oxytocin. Simply thinking about your baby, their smell, or even looking at a picture can trigger oxytocin release and lead to leaks.
  • Stress or anxiety: These emotions can also indirectly affect oxytocin and prolactin levels and potentially cause leaks.

Physical Triggers

  • Let-down reflex: This is an automatic natural response that causes your body to release milk. Some mothers might produce more milk than baby needs, and may experience more frequent leaks.
  • Engorgement: When your breasts become overly full, pressure can build up and lead to leaks.
  • Stimulation of your breasts: This can include anything from brushing against your breasts to sexual activity.
  • Changes in feeding schedule: Skipping a feed or going longer between feeds can cause your breasts to become more full and increase the risk of leaks.

Other Factors

  • Hormonal changes: Fluctuations in hormones, such as those during pregnancy or menstruation, can sometimes affect milk production and lead to leaks.
  • Certain medications: Some medications can affect prolactin levels, the hormone responsible for milk production, and potentially contribute to leaks.



When does Breast Milk Leaking Start?

Breast milk leakage can start at different times for different women, but it often begins during pregnancy or shortly after childbirth. Here are some common timelines for when breast milk leakage may start:

  • During Pregnancy: Some women notice breast milk leakage, also known as colostrum, as early as the second trimester of pregnancy. Colostrum is the first milk produced by the breasts, and it is rich in antibodies and nutrients to support the baby's early growth and development. While not all women experience leakage during pregnancy, it's a normal and common occurrence for many.
  • After Childbirth: Breast milk production typically increases significantly in the days following childbirth, as the body transitions from producing colostrum to mature milk. Many women experience breast milk leakage during this time, especially during breastfeeding or when the breasts become engorged with milk. The let-down reflex, triggered by hormones such as oxytocin, can also cause milk to leak from the breasts, even when the baby isn't nursing.
  • Throughout the Breastfeeding Journey: Breast milk leakage can continue throughout the breastfeeding journey, particularly during the early months when milk production is still establishing and regulating. Some women may notice leakage during let-down or when the breasts are full, while others may experience it more sporadically or only in specific situations. Leaking frequency and intensity can vary widely among individuals and may change over time.



When will Breast Milk Leaking Stop?

Breast milk leakage gradually decreases as your body adjusts to your baby's feeding needs. Some women continue to experience occasional leaks throughout their breastfeeding journey, while others may find that leakage stops completely after a few months.

Typically, leaks cease entirely after weaning, but it can take weeks or even months for your milk production to fully shut down. Each woman's experience with breast milk leakage is unique, and the timeline for when it stops can vary.

When Should You Be Concerned About Milk Leakage?

While breast milk leakage is a common and normal occurrence, there are some instances where it may indicate an underlying issue that requires medical attention.

  • Persistent or severe breast pain
  • Fever or flu-like symptoms
  • Unusual changes in the colour, odour, or consistency of breast milk
  • Redness, warmth, or swelling in the breast
  • Nipple discharge other than breast milk

Tips For Managing Milk Leakage

While breast milk leakage can be inconvenient, there are several strategies that mums can employ to manage it effectively.

Use High-Quality Nursing Pads

Nursing pads are an essential accessory for breastfeeding mothers, providing comfort, protection, and peace of mind during the breastfeeding journey.

  • Absorbency: Nursing pads are designed to absorb breast milk leakage, keeping the skin and clothing dry. This helps prevent discomfort, irritation, and potential skin problems such as nipple dermatitis or fungal infections.
  • Protection: Nursing pads provide a barrier between the breasts and clothing, protecting against wetness and staining. This can help breastfeeding mothers feel more confident and comfortable, especially when out in public or wearing lighter-colored clothing.
  • Discretion: Nursing pads are discreet and can be worn under clothing without being visible. This allows breastfeeding mothers to go about their daily activities without worrying about visible wet patches or leakage, helping them feel more at ease in social settings.
  • Convenience: Reusable nursing pads are eco-friendly, convenient and easy to use. They can be quickly changed as needed, providing ongoing protection against leakage throughout the day.
  • Hygiene: Nursing pads help maintain good hygiene by absorbing breast milk leakage and preventing moisture from accumulating on the skin. This can reduce the risk of skin irritation, infection, and other potential complications associated with prolonged exposure to moisture.


Supportive Nursing Bra

Nursing bras play a crucial role in supporting breastfeeding mothers throughout their journey, offering a combination of comfort, accessibility, and support that helps minimize discomfort and reduce the risk of leakage.

  • Support: Nursing bras are designed with features such as wider straps, adjustable closures, and supportive cups to provide comfort and support to the breasts, especially during breastfeeding. Proper support can help reduce the likelihood of engorgement and minimize leakage by keeping the breasts securely in place.
  • Accessibility: Nursing bras typically feature cups that can be easily unclasped or pulled down to allow for convenient breastfeeding or pumping. This accessibility allows breastfeeding mothers to respond quickly to their baby's feeding cues, which can help prevent engorgement and reduce the risk of leakage.
  • Comfort: Nursing bras are often made from soft, stretchy fabrics that accommodate changes in breast size and shape during breastfeeding. Comfortable bras can help breastfeeding mothers feel more at ease and confident, which may contribute to a smoother breastfeeding experience overall.



Nipple Balm

Some nipple balms may contain ingredients like aloe vera or calendula known for their calming and anti-inflammatory properties, offering temporary relief from discomfort and can help with

  • Dry, cracked skin: If leaks are making your nipples dry and uncomfortable, a moisturizing balm can offer relief.
  • Minor chafing: A barrier cream can protect your skin from further irritation if leaks are causing chafing.
  • Soothing soreness: Certain balms can offer temporary relief from minor soreness or stinging related to leaks.



Heating/Cooling Pads

Heat and cooling pads can potentially assist with breast milk leaks, but it depends on the circumstances and the type of leak:

Cooling pads

  • Reduce swelling: If leaks are associated with engorgement or mastitis, which cause breast swelling and discomfort, cooling pads can bring relief by constricting blood vessels and reducing inflammation. This can indirectly lessen leaks by decreasing milk production in an already overly full breast.
  • Reduce let-down reflex: Applying a cool pad to your other breast during feeding can sometimes delay or slow down the let-down reflex, potentially preventing forceful leaks that occur before your baby latches.

Heating pads

  • Encourage let-down: If leaks are associated with slow milk flow or difficulty achieving letdown, a warm pad (not hot) applied before feeding can stimulate milk production and promote a smoother flow, potentially minimizing leaks during latching.

Use a Breast Pump

Using a breast pump can be helpful for managing breast milk leakage in several ways:

  • Regulating Milk Supply: Breast pumps allow breastfeeding mothers to express milk from their breasts, which can help regulate milk supply and prevent engorgement. By removing excess milk, pumping can reduce the likelihood of leakage due to overfull breasts.
  • Relieving Engorgement: Breast pumps can be used to relieve engorgement, a common cause of breast milk leakage. Pumping can help soften the breasts and reduce discomfort associated with engorgement, making it easier for the baby to latch and breastfeed effectively.
  • Collecting Excess Milk: Breast pumps allow breastfeeding mothers to collect and store excess breast milk for later use. If leaking occurs, especially during let-down or between feedings, using a breast pump can help collect the leaked milk and prevent it from soaking through clothing.
  • Maintaining Milk Supply: Regular pumping sessions can help maintain milk supply, especially if breastfeeding is temporarily interrupted due to factors such as illness, separation from the baby, or returning to work. Pumping can help stimulate milk production and prevent a decrease in milk supply, which may reduce the frequency and intensity of breast milk leakage.
  • Providing Relief: Pumping can provide relief from discomfort associated with breast milk leakage, engorgement, or other breastfeeding-related issues. Emptying the breasts with a pump can alleviate pressure and help breastfeeding mothers feel more comfortable and at ease.



Try Different Breastfeeding Positions

While specific breastfeeding positions may not guarantee preventing leaks entirely, some positions can help minimize them.

Positions that might lessen leakage

  • Side-Lying Position: When breastfeeding while lying on your side, gravity may work to your advantage, potentially reducing the likelihood of milk leakage. This position allows the breast to naturally fall downward, which can help control the flow of milk.
  • Football Hold: In the football hold position, the baby is held at the side of the breast, with their body positioned alongside the mother's torso. This position may provide better control over the flow of milk and reduce the chance of leakage.
  • Laid-Back or Reclined Position: In a laid-back or reclined position, the mother leans back comfortably with her baby lying on top of her. This position can encourage the baby to latch deeply and may help reduce the force of milk flow, potentially minimizing leakage.
  • Cross-Cradle Hold: In the cross-cradle hold, the baby's head is supported by the hand opposite the breast being nursed. This position allows the mother to have better control over the baby's latch and positioning, which can help reduce milk leakage.
  • Upright Position: Some women find that breastfeeding in a more upright position, such as sitting or standing, can help reduce milk leakage. This position may allow for better control over the flow of milk and minimize the chances of milk leaking out.

Additional tips

  • Experiment with different positions: Find what feels comfortable and promotes efficient milk removal for both you and your baby.
  • Apply gentle pressure: If you feel a let-down coming on, try applying gentle pressure to your other breast using your fingers or a milk catcher to prevent leaks.
  • Express or pump cautiously: While expressing can relieve pressure sometimes, avoid overdoing it as it can signal your body to produce more milk and worsen leaks.

Practice Relaxation Techniques

Stress and anxiety can exacerbate milk let-down and increase the likelihood of leakage. Relaxation techniques such as deep breathing, meditation, and gentle stretching exercises offer breastfeeding mothers valuable tools for managing stress and promoting relaxation.

By reducing stress hormone levels and stimulating the release of oxytocin, these techniques facilitate smoother milk let-down and minimize the risk of spontaneous leakage during breastfeeding sessions. Additionally, relaxation techniques create a calm and peaceful environment for both mother and baby, enhancing the breastfeeding experience and fostering a stronger bond between the two.

Furthermore, relaxation techniques help alleviate physical tension in the body, including tension in the chest and breast area, which can impede milk flow and contribute to discomfort during breastfeeding. By releasing physical tension, these techniques promote relaxation in the breast tissue, allowing for more comfortable and efficient milk flow.


Nursing Covers

Nursing covers can be a valuable accessory, offering coverage, privacy, and comfort for breastfeeding mothers.

  • Coverage: Nursing covers can be draped over the chest and breast area, helping to conceal any wet patches or leakage that may cause embarrassment.
  • Privacy: Nursing covers offer privacy and discretion for breastfeeding mothers, allowing them to breastfeed comfortably and discreetly in public settings. This can help alleviate anxiety and provide peace of mind for mothers who may be self-conscious about breast milk leakage.
  • Comfort: Creating a cozy and comfortable environment for breastfeeding may help stimulate milk let-down and encourage successful breastfeeding sessions. This can be particularly beneficial for mothers who experience leaking in response to breastfeeding cues or let-down reflex.
