Oxytocin and the Let-Down Reflex: Why You May Leak Milk Between Feedings

What is the let-down reflex?

The let-down reflex is a natural response of your body to release breast milk from your mammary glands. This reflex is controlled by oxytocin , also known as the “cuddle hormone.” Oxytocin is released in response to stimuli such as your baby’s sucking, skin-to-skin contact, or even hearing your baby cry. This can cause your breasts to leak milk even when you’re not feeding.

Why do you leak milk between feedings?

Many mothers find that their breasts spontaneously leak milk between feedings. This can have several causes:

• Strong let-down reflex: Some mothers have a strong reflex, which causes milk to be released in response to mild stimuli.

• Overproduction of milk: If your body produces more milk than your baby drinks, it can put pressure on the mammary glands.

• Oxytocin Triggers: Sounds, smells, or even thinking about your baby can set off a response.

• Irregular feeding: If you skip feedings or your baby drinks less often, your body can still release milk.

  
  

What can you do about milk leakage?

While leaks may be unavoidable, there are a few ways to deal with them:

• Use collection cups: Instead of wasting milk, you can wear collection cups like these from Medela in your bra to collect breast milk for later use.

• Wear nursing pads: Any nursing pad are individually wrapped, meaning you can easily take them with you on the go and always have a clean solution on hand. Not only do they keep your bra dry and comfortable, they also protect your nipples from unwanted bacteria.

• Pump or feed regularly: This can help reduce excess pressure in your breasts.

• Gently press your nipple: This may temporarily stop the leak if you are in a public place.

  
  

Why collection cups?

Collection cups are a convenient solution to collect breast milk and prevent spillage. They are discreet, comfortable and can be easily worn in your bra. Unlike nursing pads, which absorb milk, collection cups allow you to store and use the milk later.

Conclusion

Milk leakage between feedings is normal and a sign that your body is responding well to oxytocin. By using collection cups, you can conveniently store milk and reduce waste. At the same time, I also recommend purchasing nursing pads since you will not always be able to wear the collection cups.
