Colostrum is the first form of milk produced by the mammary glands of mammals immediately following the delivery of the newborn. It is a thick, yellowish substance that is rich in nutrients and antibodies, making it essential for the newborn’s health and development. Colostrum is often referred to as “liquid gold” because of its color and immense value to the newborn.
The Role of Colostrum in Newborn Nutrition
Colostrum plays a critical role in the early days of a newborn’s life. It is highly concentrated, with small amounts packed with proteins, vitamins, and antibodies. These components are crucial for the newborn’s immune system, helping to protect them from infections and diseases. Additionally, colostrum helps to establish a healthy gut microbiome, which is important for digestion and long-term health.
How Much Colostrum Does a Newborn Need?
Day 1: The First 24 Hours
In the first 24 hours after birth, a newborn’s stomach is very small, roughly the size of a marble or cherry, holding about 5-7 milliliters (ml) per feeding. Newborns typically consume about 1 teaspoon of colostrum per feeding. Despite its small volume, colostrum is highly concentrated, providing all the essential nutrients the baby needs.
Day 2: The Second Day
As the newborn continues to feed, their stomach capacity gradually increases. On the second day, the baby’s stomach can hold approximately 10-13 ml per feeding. The newborn will typically consume 15-20 ml of colostrum per feeding by the end of the second day. This gradual increase helps the baby transition smoothly to larger volumes of milk.
Day 3: Transition to Mature Milk
By the third day, the baby’s stomach has grown to the size of a walnut, holding about 22-27 ml per feeding. The mother’s milk supply will begin to transition from colostrum to more mature milk. This transition usually occurs between the third and fifth day postpartum. During this period, the baby will consume around 30 ml of milk per feeding, with colostrum still present in smaller quantities.
Signs That a Newborn Is Getting Enough Colostrum
Weight and Growth Monitoring
One of the most important indicators that a newborn is getting enough colostrum is weight monitoring. It is normal for newborns to lose up to 7-10% of their birth weight within the first few days. However, they should start to regain this weight by the end of the first week. If the baby is losing more weight than expected or not regaining weight, it may be a sign that they are not getting enough colostrum.
Diaper Output
Diaper output is another reliable indicator of adequate colostrum intake. In the first 24 hours, the newborn should have at least one wet diaper and one or more meconium (first stool) diapers. By the third day, the baby should have at least three wet diapers and two to three bowel movements per day. The stools should be changing from dark meconium to a lighter, yellowish color, indicating that the baby is digesting colostrum well.
Behavioral Signs
A well-fed newborn will be alert and content after feeding. They may also show signs of satisfaction, such as releasing the breast or falling asleep. A baby who is not getting enough colostrum may be fussy, restless, or constantly hungry. These behavioral signs should be monitored closely to ensure the baby is receiving enough nourishment.
Factors Influencing Colostrum Production and Intake
Maternal Health and Nutrition
The mother’s health and nutrition play a significant role in colostrum production. A well-balanced diet rich in vitamins and minerals supports optimal colostrum production. Hydration is also crucial, as dehydration can reduce milk supply. Stress, illness, or fatigue can also affect the quantity and quality of colostrum.
Breastfeeding Techniques
Proper breastfeeding techniques are essential for ensuring that the newborn receives enough colostrum. The baby should have a good latch, covering the areola with their mouth to effectively extract milk. Frequent feeding is encouraged, especially in the first few days, to stimulate milk production. Skin-to-skin contact between the mother and baby can also enhance milk production and encourage feeding.
Medical Interventions
Certain medical interventions during birth, such as cesarean sections or the use of certain medications, may delay the onset of milk production. In these cases, colostrum may still be produced, but in smaller quantities. It is important to monitor the baby’s intake and seek medical advice if there are concerns about colostrum supply.

Supplementation: When Is It Necessary?
Indicators for Supplementation
In some cases, supplementation with formula or donor milk may be necessary if the baby is not receiving enough colostrum. Indicators for supplementation include significant weight loss, low diaper output, or jaundice. Supplementation should be done under the guidance of a healthcare professional to ensure that the baby is receiving adequate nutrition.
Methods of Supplementation
There are several methods of supplementation, including syringe feeding, cup feeding, or using a supplemental nursing system (SNS). These methods allow the baby to receive additional nutrition while still practicing breastfeeding. It is important to continue breastfeeding alongside supplementation to encourage milk production and bonding.
The Transition to Mature Milk
Timing of Transition
The transition from colostrum to mature milk usually occurs between the third and fifth day postpartum. During this time, the mother may notice her breasts becoming fuller and heavier, a sign that milk production is increasing. The baby’s feeding patterns may also change, with more frequent and longer feeding sessions.
Nutritional Differences Between Colostrum and Mature Milk
While colostrum is rich in proteins and antibodies, mature milk contains higher levels of fat and lactose, providing the baby with more calories for growth. However, mature milk still contains important antibodies and immune factors, continuing to protect the baby from infections. The gradual transition ensures that the baby’s digestive system can adjust to the changing composition of the milk.
Long-Term Benefits of Colostrum
Immune System Support
One of the most significant long-term benefits of colostrum is its role in supporting the immune system. The antibodies and immune factors present in colostrum help to protect the baby from infections and diseases during the early stages of life. This protection extends beyond infancy, as the immune system continues to develop.
Digestive Health
Colostrum also plays a key role in establishing a healthy gut microbiome. The beneficial bacteria introduced through colostrum help to colonize the gut, promoting healthy digestion and reducing the risk of gastrointestinal issues. A healthy gut microbiome is also linked to a lower risk of allergies and autoimmune diseases later in life.
Growth and Development
The nutrients in colostrum, including proteins, vitamins, and minerals, support the baby’s growth and development. Colostrum contains growth factors that help to develop the baby’s organs and tissues, setting the foundation for healthy growth. The high protein content in colostrum also supports muscle development and tissue repair.
Conclusion
Colostrum is a vital component of a newborn’s early nutrition, providing the essential nutrients and antibodies needed for health and development. Although the quantities consumed are small, the impact of colostrum is profound, supporting the immune system, digestive health, and overall growth. By understanding the importance of colostrum and monitoring the baby’s intake, parents can ensure that their newborn receives the best start in life.
