What Causes Overnight Engorgement?

Overnight engorgement is typically caused by an accumulation of milk in the breasts. Several factors can contribute to this uncomfortable condition:

Milk Production Cycle

Your body produces milk on a supply-and-demand basis. When your baby starts to sleep longer stretches at night, your breasts continue to produce milk at the usual rate, leading to overfull breasts. This is especially common in the early days postpartum when milk production is still adjusting.

Changes in Feeding Patterns

Skipping night feedings or reducing the frequency of breastfeeding sessions can cause engorgement. If your baby suddenly sleeps through the night or you miss a pumping session, milk accumulates, causing discomfort.

Blocked Milk Ducts

Sometimes, milk ducts can become blocked due to improper latching by the baby, infrequent or incomplete emptying of the breasts, or pressure on the breast from a tight bra or sleeping position. Blocked ducts prevent milk from flowing normally, contributing to engorgement.

Hormonal Fluctuations

Hormones like prolactin and oxytocin regulate milk production. Any changes in these hormone levels can affect milk supply and lead to engorgement. Stress, fatigue, and certain medications can also influence these hormones.

Overproduction of Milk

Some mothers naturally produce more milk than their baby needs. This overproduction can lead to rapid filling of the breasts, resulting in engorgement if not managed by regular feeding or pumping.

How To Prevent Engorgement While Sleeping?

Preventing overnight engorgement is key to comfortable and effective breastfeeding. Here are some strategies to help minimize the risk of engorgement while you sleep:

Regular Nighttime Feedings

If possible, try to feed your baby at regular intervals throughout the night. If your baby starts sleeping longer stretches, consider pumping right before you go to bed or even once during the night to relieve pressure and maintain your supply.

Optimal Breastfeeding Techniques

Ensure your baby is latching correctly. A good latch helps your baby empty the breast thoroughly, reducing the risk of engorgement. Consult a lactation consultant if you have concerns about your baby's latch.

Alternate Breasts

Start each feeding on a different breast and ensure both breasts are being emptied consistently. This not only helps in maintaining even milk production but also prevents the buildup of milk that leads to engorgement.

Pump Management

For mothers experiencing high milk production, using a breast pump to express milk can prevent engorgement. Pumping should be balanced—not too frequent to avoid stimulating excessive milk production, but enough to relieve fullness.

Cabbage Leaves and Cold Compresses

Applying cold compresses or chilled cabbage leaves to your breasts can reduce swelling and provide relief from engorgement. This method can be particularly soothing after a nighttime feeding or pumping session.

Proper Sleep Positioning

Sleeping on your back or on a slight incline can help prevent milk from accumulating excessively in the breasts. Avoid lying on your stomach or in positions that put pressure on your breasts.

Best Practices for Nighttime Feeding and Pumping

Nighttime feeding and pumping can be a challenge, but with the right practices, you can prevent engorgement and make it a smoother experience for both you and your baby. Here are some best practices to optimize your nighttime routine:

  • Stay Consistent: Feed or pump at regular intervals during the night. Aim for at least one session every 3-4 hours to maintain milk supply and prevent engorgement.
  • Pump to Comfort: If your baby skips a feeding, pump just enough to relieve pressure. This prevents discomfort and reduces the risk of clogged ducts. Avoid fully emptying the breasts to prevent signaling your body to increase milk production further.
  • Alternate Breasts: Start each feeding on a different breast. This ensures both breasts are emptied regularly, maintaining balance in milk production.
  • Relaxation Techniques: Create a relaxing environment for nighttime pumping. Dim the lights, play soothing music, or practice deep breathing to make the experience more pleasant.
  • Comfortable Pump Setup: Ensure your pump is set up properly and that you have the right flange size. An ill-fitting flange can make pumping painful and less effective.
  • Gradual Weaning: If you need to reduce nighttime feedings, do it gradually. This helps your body adjust and prevents sudden engorgement.

Tips to Relieve Engorgement

Here are some practical tips to help alleviate the discomfort associated with engorged breasts:

  • Warm Compresses Before Feeding: Applying a warm compress or taking a warm shower before breastfeeding can help stimulate milk flow and soften the breast, making it easier for your baby to latch properly.
  • Use a Breast Pump with Heating Feature: Consider using a breast pump with a heating feature to help soften the breast tissue and make pumping more comfortable during engorgement. The eufy wearable breast pump, for instance, is a hands-free pump equipped with a built-in heating plate and a precision temperature sensor that ensures uniform warmth.

It offers seven adjustable heat settings between 95°F and 105°F, which can help enhance milk flow and reduce clogs. The comforting warmth and skin-like feel of the soft silicone can make a significant difference in managing engorgement effectively.

  • Cold Compresses After Feeding: After feeding or pumping, applying cold compresses or chilled cabbage leaves to your breasts can reduce swelling and pain. Ensure that the compress is not too cold to avoid discomfort.
  • Gentle Massage: Gently massaging your breasts in a circular motion from the chest wall toward the nipple before and during feeding can help alleviate engorgement. This technique helps to move the milk through the ducts and can prevent blockages.
  • Proper Bra Fit: Wear a well-fitting, supportive bra that does not constrict your breasts. Avoid underwire bras if possible, as they can place pressure on the milk ducts and potentially lead to clogged ducts.
  • Frequent Feedings: Do not delay or skip feedings, even if it is painful to breastfeed. Frequent feeding is essential to manage engorgement because it helps maintain regular milk flow and prevents the breasts from becoming overly full.
  • Pain Relief: If necessary, take over-the-counter pain relief like acetaminophen to help manage the discomfort. Always check with your healthcare provider before taking any medication while breastfeeding.


Learning how to prevent engorgement overnight is key to maintaining comfort and milk supply during your breastfeeding journey. By understanding the causes and implementing the preventive measures discussed, such as optimizing your nighttime feeding and pumping routine and using relief techniques, you can significantly reduce the chances of becoming uncomfortably engorged. Remember, each mother's situation is unique, so it might take some adjustments to find what works best for you. Stay in tune with your body's responses and don't hesitate to seek support from lactation consultants if you find yourself struggling.


How often should I pump at night to prevent engorgement?

To prevent engorgement, aim to pump at least once during the night, especially if your baby is sleeping longer stretches. Pumping every 3-4 hours can help maintain your milk supply and prevent discomfort.

Are there any specific breastfeeding positions that help reduce overnight engorgement?

Yes, certain breastfeeding positions can help reduce engorgement. The "laid-back" or reclined position can be beneficial as it allows gravity to assist in milk flow. Side-lying nursing can also be comfortable and effective, especially during nighttime feedings.

Can I go 8 hours without pumping at night?

It's generally not recommended to go 8 hours without pumping, especially if you're breastfeeding. Prolonged periods without emptying the breasts can lead to engorgement, clogged ducts, or a decrease in milk supply. It's best to pump or nurse every 3-4 hours, even at night, to prevent these issues.
