Colostrum: The First Superfood Your Newborn Needs
November 6, 2025
You can begin feeding your baby within minutes after delivery. The first secretion that comes immediately after birth is not milk, but colostrum. This is a sticky yellow fluid that is a superfood, which promotes growth and provides protection for the newborn.
Colostrum Should be the First Food For Newborns
Colostrum is the first milk you produce for 2- 5 days after birth. Colostrum contains everything your baby needs to adjust from life in the womb to life in the outside world. It is beneficial for all infants, especially for pre-term babies. A few teaspoons of colostrum per day is enough for your baby initially, as a newborn’s stomach is tiny, so the little colostrum you make is enough during the first few days. Even these small amounts provide all the essential nutrients and immune protection.
Your baby’s stomach grows constantly and, in a few days, will be stretched enough to accommodate milk at every feed. After this period, you will produce transitional milk that is a mix of colostrum and milk, which prepares your baby for the more mature milk.
When Does Colostrum Appear?
Colostrum production starts between 12–16 weeks of pregnancy and may be noticeable as early as the second trimester. Some women may leak small amounts before birth. After delivery, the drop in progesterone triggers milk production, and colostrum is ready for the newborn immediately or within the first 24 hours.
Composition of Colostrum
Colostrum is highly nutrient-dense and contains:
- Proteins: High levels of protein help newborns grow and are easier to digest due to low fat content. Key proteins include lactoferrin (prevents infections) and epidermal growth factor (supports cell growth).
- Immunoglobulins (IgA): Protect the baby against infections and help establish immunity.
- Leukocytes: White blood cells that fight harmful bacteria and viruses.
- Vitamins & Minerals:
- Vitamin A: Supports vision, skin, and immunity.
- Magnesium: Helps heart and bone development.
- Copper & Zinc: Boost the immune system.
- Low fat and sugar: Makes it easier for babies to digest.
Colostrum provides four times more zinc and twice as much copper than regular breast milk.
Benefits of Colostrum for Babies
Colostrum provides multiple benefits, including:
- Complete nutrition in an easily digestible form: Low in fat and sugar but high in protein, vitamins, and minerals.
- Boosts immunity: Contains antibodies (immunoglobulin A) and white blood cells that protect against infections.
- Protects against low blood sugar in infants.
- Supports gut health: Coats the stomach and intestines to prevent harmful bacteria from entering.
- Acts as a natural laxative: Helps clear meconium and reduce the risk of jaundice.
- Supports growth and development: Provides nutrients for proper eye, skin, heart, and bone development.
- Contains essential minerals: Zinc, copper, and magnesium help strengthen the immune system and support heart and bone development.
- Contains growth-promoting proteins: Such as lactoferrin and epidermal growth factor, which protect against infections and promote cell growth.
You Don’t Have to Worry Whether You are Producing Enough Colostrum
At birth, your baby’s stomach is about the size of a marble, so just a small amount of colostrum is enough. Indicators that your baby is feeding effectively include:
- Feeding at least 8 times a day
- Wetting at least 6 diapers a day
Keep in mind that frequent feeding helps increase your milk supply. Feed your baby on demand, and both of you will do well.
Collecting and Storing Colostrum
For babies who may need extra support, such as preterm infants or babies born via planned C-section, it is possible to collect colostrum before birth, starting around the 37th week of pregnancy.
Storage tips:
- Keep equipment clean to avoid bacteria.
- Store small amounts in sterile containers or syringes (up to 5 ml).
- Refrigerate throughout the day and freeze for 4–6 months.
- Label containers with the date and time.
- Thaw in lukewarm water and use within 24 hours.
Transition from Colostrum to Breast Milk
Breast milk changes in three stages:
- Colostrum (Day 1–5): Thick, yellow, and nutrient-rich.
- Transitional Milk (Day 5–14): Mixture of colostrum and mature milk; volume increases, protein decreases, fat and lactose rise.
- Mature Milk (After 2–6 Weeks): Thin, white, rich in fat, protein, lactose, and immune components to meet the growing baby’s needs.
