Foremilk versus Hindmilk: Truth or Myth?

Updated: Apr 25

The Debate!

The debate over foremilk and hindmilk often causes unnecessary concern among new mothers. Some worry about switching breasts too early during feedings and whether their child is receiving enough nutrient-rich hindmilk. However, it's important to understand that all breast milk, from the beginning to the end of a feeding session, contains both foremilk and hindmilk. Initially, the milk is lower in fat (foremilk), but as the feeding continues, the fat content increases, culminating in the creamier hindmilk. Effective draining of the breast ensures the baby accesses more hindmilk, which is located further back in the milk ducts.


How do I know if my baby is getting balanced milk?

To ascertain if your baby is getting sufficient milk in the first months, look for signs such as feeding at least eight times in 24 hours, weight gain of 5-8 ounces per week, regular wet and yellow-poop diapers, and softer breasts post-feeding. These indicators suggest your baby is well-nourished without the need to monitor feeding times closely or worry about hindmilk intake.


What are signs of too much foremilk?

However, if your baby experiences symptoms like green, frothy stools, excessive gas, or choking during feedings, it could indicate an oversupply of milk or a dietary intolerance. For those with a substantial milk supply, reducing the flow can help manage lactose digestion and alleviate discomfort. Techniques to slow milk flow include leaning back during feedings and positioning the baby upright to better manage the fast flow or side lying. Moreover, feeding from one breast per session can regulate milk supply, ensuring your baby consumes more fatty milk for fullness and satisfaction.

Should you notice your breasts becoming uncomfortably full, you may need to express milk from the unused breast lightly or you can use a gentle manual expresser like the Boon Trove. Monitoring your baby's cues is crucial, as feeding patterns may change around 2-3 months, possibly requiring feeding from both breasts again. Additionally, natural remedies like sage tea can help adjust milk supply, though responses vary, and consultation with a lactation consultant may be beneficial.


This overview simplifies the foremilk and hindmilk concept, emphasizing that breastfeeding success lies in understanding and responding to your baby's needs rather than adhering strictly to feeding strategies or schedules.



The discussion surrounding foremilk and hindmilk in breastfeeding, often seen as a source of concern among new mothers, is largely based on misconceptions. Both La Leche League International and KellyMom, reputable sources on breastfeeding, clarify that the breast produces only one type of milk, which varies in fat content over the course of a feeding session. The initial milk, known as foremilk, is not necessarily low in fat; its composition depends on the time since the last feeding and how effectively the breast is emptied. As the feeding continues, the milk becomes richer in fat, transitioning to what is termed hindmilk. This change is gradual and natural, ensuring that the baby receives all the necessary nutrients regardless of the precise timing of the switch between breasts.

La Leche League International emphasizes that the breast's milk-making cells produce the same kind of milk throughout a feeding. The variation in fat content is related to the milk's storage time in the ducts and the degree of breast emptying during feeding. They also address lactose overload, previously known as foremilk/hindmilk imbalance, explaining that most babies can process lactose in normal volumes of milk without issue. Problems may arise with very large intakes of breastmilk, particularly if it is low in fat, leading to symptoms like gassiness or green, frothy stools. However, this is typically related to feeding patterns or milk supply issues rather than an inherent problem with the milk itself​​.

KellyMom provides a similar perspective, noting that the breast only produces one type of milk, with fat content increasing as the feeding progresses. This is due to the mechanics of milk release and storage within the breast. The distinction between foremilk and hindmilk is more about the timing within a feeding session rather than different types of milk. They also explain that multiple let-downs occur during a feed, which can affect the milk's fat content. Importantly, they advise against switching breasts while the baby is actively nursing to ensure the baby receives milk with gradually increasing fat content throughout a feed​​.

These insights should reassure new mothers that breastfeeding naturally provides for their baby's nutritional needs. The focus should be on effective feeding techniques and responding to the baby's cues rather than undue concern over foremilk and hindmilk.
