How to Manage a Sudden Drop in Milk Supply

If you’re worried that your breast milk supply has suddenly decreased, there are several possible reasons why this might be happening. Understanding the causes and taking the right steps can help you increase your milk production and continue breastfeeding successfully.

Why You May Think Your Breast Milk Is Drying Up

Many mothers believe their milk supply is low when it’s actually normal. When the initial engorgement phase passes, breasts become softer, which can be mistaken for a drop in supply. However, milk is primarily produced during feedings, so softer breasts do not necessarily mean less milk.

Additionally, babies go through growth spurts—commonly at 3 weeks, 6 weeks, and 3 months—during which they nurse more often. This increased feeding frequency can be mistaken as a sign of low milk supply, when in reality, it’s just your baby’s way of stimulating more production.

If you have introduced solid foods at around 6 months, your milk supply will gradually decrease as your baby consumes more solids. However, this change happens over time and does not immediately result in a sudden drop.

Signs Your Milk Supply Is Decreasing

If your milk supply is truly declining, you may notice the following signs:

• Slow or no weight gain – Babies should gain 1.5 to 2 pounds per month in the early months. Slowed weight gain may indicate a drop in milk intake.
• Signs of dehydration – Fewer wet diapers, dark urine, dry skin, and crying without tears could signal dehydration.
• Fussiness and lethargy – If your baby is unusually fussy or struggling to stay awake while nursing, they may not be getting enough milk.

Common Causes of a Sudden Drop in Milk Supply

Several factors can contribute to a sudden decrease in milk production:

• Stress – Emotional and physical stress can affect milk production.
• Sleep deprivation – Lack of sleep can reduce milk supply over time.
• Time away from baby – If you are away from your baby for extended periods and not nursing or pumping frequently, your milk supply may decline.
• Infrequent pumping – Not pumping often enough can lead to reduced milk production, especially for working moms.
• Dieting or poor nutrition – Breastfeeding requires extra calories. A diet too low in calories can impact supply.
• Medications – Some medications, including antihistamines and birth control pills, can lower milk production.
• Hormonal changes – The return of your menstrual cycle or pregnancy can cause fluctuations in supply.
• Thyroid issues – An underactive or overactive thyroid can affect milk production.
• Breastfeeding problems – Engorgement, clogged ducts, or a poor latch can reduce supply over time.

How to Increase Your Milk Supply

If you notice a decrease in supply, here are some effective strategies to boost milk production:

• Prioritize self-care – Rest, stay hydrated, and eat a balanced diet to support milk production.
• Reduce stress – Seek emotional support from family or professionals if needed.
• Increase nursing frequency – Nurse or pump more often to stimulate supply.
• Try a nursing vacation – Spend extra time skin-to-skin with your baby to encourage more feedings.
• Consult a lactation expert – A lactation consultant can help resolve latch or supply issues.

What to Do If You’re Exclusively Pumping

If you rely on pumping, these tips can help maintain and increase your supply:

• Add an extra pumping session – Pumping more frequently can stimulate milk production.
• Prioritize pumping at work – Sticking to a schedule is essential for maintaining supply.
• Check your pump – Ensure your breast pump is working efficiently.
• Spend time skin-to-skin with your baby – This can trigger letdown and improve milk flow.
• Try power pumping – This technique mimics cluster feeding and encourages higher milk output.

A sudden drop in milk supply can be concerning, but with the right steps, you can restore production and continue your breastfeeding journey. If you’re struggling, seek guidance from a lactation consultant or healthcare provider for personalized support.
