Breastmilk production is a complex process influenced by many factors. While it is possible for some women’s milk supply to fully cease, this is relatively rare in most cases. With the right support and techniques, mothers can often re-establish milk production even after extended periods without nursing or pumping. Understanding the physiology behind milk supply and implementing evidence-based strategies can help ensure continued breastfeeding success.
What affects breastmilk supply?
Several key hormones regulate breastmilk production, primarily prolactin and oxytocin. Prolactin signals the breasts to make milk, while oxytocin causes milk to eject during feeding. These hormones work together in response to nipple stimulation from nursing or pumping.
Milk supply is closely tied to milk removal. The more milk that is emptied from the breasts on a regular basis, the more prolactin and oxytocin are produced to make more milk. Going for extended periods without nursing or pumping leads to a decline in these hormones and lower production over time.
Other factors also impact milk supply, including:
- Stage of lactation – Supply naturally regulates 3-6 weeks postpartum but remains responsive to baby’s needs
- Maternal health and anatomy – Medical conditions, breast surgery/injury, insufficient glandular tissue can affect milk production
- Medications – Some supplements and medications can impede milk synthesis
- Baby’s nursing habits – Infant feeding patterns, ability to transfer milk, and developmental stage all influence milk removal
- Stress and fatigue – High stress inhibits let-down reflex and milk ejection
- Nutrition and hydration – Poor maternal diet and dehydration can reduce supply
Is it possible for breastmilk to fully dry up?
In most cases, the complex hormonal interactions that control lactation prevent breastmilk from ever fully drying up, as long as there is appropriate glandular breast tissue present. However, there are a few scenarios in which milk supply can become extremely low or non-existent:
- Post-weaning – After gradually weaning a baby, eventually milk production slows and ceases as nursing/pumping ends entirely. This is a normal part of weaning.
- Menopause – The hormonal changes of menopause eventually lead to complete cessation of breastmilk.
- Sheehan’s syndrome – A rare postpartum complication involving pituitary gland damage that disrupts milk supply.
- Insufficient glandular tissue – A congenital or surgical condition where minimal milk-making tissue is present.
Outside of these specific circumstances, most mothers are physiologically capable of re-lactating to some degree with proper support. However, restarting milk production after a significant absence of nipple stimulation requires dedication and time.
How long can milk production persist without nursing/pumping?
Milk supply begins to gradually decline any time regular, effective milk removal stops. However, the length of time production can continue without stimulation varies based on individual factors:
- Stage of lactation – Early postpartum (0-6 weeks), supply is more sensitive to disruption but rebounds quickly.
- Breast storage capacity – Women with larger capacity can go longer between removals.
- Breastfeeding history – Multiparous mothers may maintain supply better than new mothers.
- Nipple stimulation – Some women can leak or experience let-downs with non-milk removal stimulation.
For most mothers, milk production begins to significantly drop within:
- 48-72 hours without breast stimulation in early postpartum period
- 5-7 days for established milk supply around 2-6 months
- 14+ days after long-term breastfeeding for 12+ months
However, again, complete cessation of established milk supply in absence of weaning, menopause or medical issues is uncommon.
Restoring breastmilk supply after absence of feeding
Re-establishing breastmilk production requires rebuilding prolactin and oxytocin receptors through consistent, around-the-clock nipple stimulation. This process is called relactation. The key factors for successful relactation include:
- Nursing/pumping frequency – Aim for 8-12 times per 24 hours, including night feeds
- Nursing/pumping technique – Ensure proper latch and emptying to maximize stimulation
- Breast massage and compression – Enhance let-down and milk ejection
- Skin-to-skin contact – Promotes oxytocin release
- Adequate nutrition/hydration – Support milk synthesis
- Reduced stress – Help let-down reflex
- Medications – Galactagogues can assist in some cases
- Support and encouragement – From lactation consultants, community, and family
Depending on variables like how long production has declined and unique body factors, re-lactation can take anywhere from a few days to a few weeks of consistent effort. Tracking metrics like milk output, oxytocin letdowns, and baby satisfaction helps gauge progress.
Tips for restarting breastmilk supply
Strategies to help rebuild milk production after a period of absence include:
- Begin breast stimulation as soon as possible after stopping
- Hand express colostrum/milk between feedings
- Use lactation massagers or pumps if unable to directly nurse
- Offer both breasts at each feeding session
- Ensure proper flange size if pumping
- Power pump 1-2x per day by clustering pump sessions
- Try breast compression and massage during/between feeds
- Supplement at breast with donor milk or formula if needed
- Get professional lactation support and encouragement
Mother’s milk tea, oats, and staying hydrated may also support the re-lactation process. Prescription galactagogues should only be considered after ruling out other issues with a medical provider.
How long does it take to restart breastmilk production?
The timeline for relactation varies significantly based on individual circumstances. The average timeframes reported in studies include:
- Within 5-7 days: Mothers relactating in early postpartum period
- 1-3 weeks: Mothers relactating after gradual weaning
- 3-8 weeks: Mothers relactating after milk supply absence for 1 month or longer
However, there are well-documented cases of adoptive mothers beginning lactation and milk production taking many months of effort. Consistency and diligence are key.
Signs milk supply is increasing during relactation
Tracking certain signs can help determine if efforts to restart breastmilk production are succeeding, including:
- Sensation of let-down reflex during feeding sessions
- Leaking or dripping milk between feedings
- Breast fullness between feedings
- Increase in pumped milk volume over time
- Baby satisfaction after feeding and appropriate weight gain
- Changes in breast size, appearance, and feeling of firmness
Measuring pumped output and monitoring baby behavior provides quantitative metrics to follow progress. Even small amounts of milk restarting are encouraging.
When to seek help with relactation
Despite best efforts, some women struggle to regain milk supply without additional support. Consulting a lactation consultant or other breastfeeding specialist is advisable if:
- No improvement in milk production after 1-2 weeks of consistent effort
- Ongoing insufficient milk volume despite relactation techniques
- Baby is not satisfied after feedings or has poor weight gain
- Significant nipple/breast pain or damage from relactation efforts
- Need for advice on prescription galactagogues
- Emotional distress from difficulty relactating as desired
An International Board Certified Lactation Consultant can help assess potential barriers, provide evidence-based guidance, and improve odds of relactation success.
Common reasons relactation may not progress
While many mothers successfully regain milk production after it declines, some common reasons it may not progress as desired include:
- Insufficient glandular tissue or breast surgery limiting supply
- Hormonal birth control or medications inhibiting lactation
- Underlying medical conditions affecting milk synthesis
- Ineffective feeding technique and milk removal
- Unidentified physical impediments or latch challenges
- Inadequate nipple stimulation frequency/intensity
- Not addressing factors negatively affecting milk ejection
Getting professional lactation help to identify and address any underlying issues is key. Anatomical, hormonal, and mechanical factors may require specific interventions to overcome.
Accepting if full relactation is not feasible
While most mothers can regain at least some breastmilk production with dedication and support, full relactation may not be possible in all situations despite best efforts. Reasons it ultimately may not be feasible include:
- Menopause or post-weaning
- Primary lactation failure due to insulin-dependent diabetes, hypopituitarism, or other conditions
- Breast glandular tissue deficiency from surgery, radiation, or anomalies
- Specific medications that severely inhibit lactation
- Psychological aversion to breastfeeding/pumping
Coming to terms with partial or minimal relactation success involves processing feelings of disappointment, frustration, sadness, or even grief. Additional emotional support and counsel may help cope with the realities of the situation.
Alternatives if full milk supply cannot restart
If despite extensive efforts milk production does not fully return, alternatives to provide breastmilk include:
- Mixing any amount of own milk with donor milk or formula
- Exclusively providing milk from a donor milk bank
- Using supplemental nursing systems at breast
- Focusing on non-nutritive nursing for comfort
Even small amounts of mom’s own milk provide valuable advantages. Continuing to nurse or pump as able also maintains potential for improvement over time.
Preventing breastmilk supply from fully drying up
The best way to avoid milk production completely stopping is:
- Consistent, effective breast drainage when away from baby
- Not going longer than 5-7 days without nursing or pumping
- Promptly addressing any breastfeeding problems as they arise
- Having lactation support lined up if issues occur
- Avoiding medications and herbs that inhibit milk synthesis
- Taking care of physical and mental health needs to prevent drops in supply
While full cessation of established breastmilk is uncommon, being proactive helps prevent irreversible drying up. Watching for early supply changes and responding promptly is key.
Conclusion
While breastmilk production diminishes without consistent removal, complete drying up tends to be an exception, not the norm for most mothers. Restarting supply through diligent relactation techniques can often succeed within days or weeks. Obtaining skilled support to identify any underlying barriers and applying evidence-based strategies focused on rebuilding milk-making hormones maximizes relactation chances. With dedication and perseverance, many mothers can fully or partially regain milk supply even after extended absence of nursing/pumping.
