What Is Colostrum?
"Colostrum" is the milk a mother's body produces after her baby is born, although production may begin in late pregnancy. If you are a new mom and notice that your milk is not white or clear, there is no need to be alarmed. This color comes from "beta-carotene," the same substance found in "yellow and orange fruits and vegetables."
The Different Stages of Breast Milk
The properties of breast milk change over time after a baby is born, adapting to the baby's changing needs at each stage. Here is what breast milk is like at each stage.
Colostrum
The first milk a mother produces after her baby is born is called "colostrum." It is pale yellow and very thick. Although produced in smaller amounts than regular breast milk, it is rich in beneficial components. It is often compared to a baby's first natural vaccine, providing immune protection, helping prevent infection, and supporting growth. The World Health Organization (WHO) recommends starting breastfeeding within the first hour after birth so that babies receive colostrum as soon as possible.
Transitional Milk
After colostrum, breast milk begins to change into transitional milk. Transitional milk has characteristics similar to colostrum, but its volume increases.
Mature Milk
Around 2-4 weeks after birth, breast milk begins to change into mature milk. Mature milk contains more water and a variety of nutrients sufficient to meet a growing baby's needs.
The Benefits of Colostrum
Giving colostrum early in a baby's life offers many benefits for growth and for both physical and brain health. Beyond its known nutritional properties, colostrum also has important medical and disease-prevention value, making it highly valued.
Immune system: Colostrum contains substances that help stimulate a baby's immune system, such as antibodies (immunoglobulins) and white blood cells called lymphocytes, which help protect against infections and various diseases.
High-quality protein: Colostrum contains high-quality protein with high biological value, helping build a baby's tissues and organ systems.
Antioxidants: It contains antioxidants that help reduce the risk of chronic diseases in babies.
Brain development: Colostrum contains substances that support a baby's brain development, influencing learning and cognitive development.
Reduced allergy risk: Receiving colostrum early in life can help reduce a baby's risk of allergies.
Supporting baby care: Feeding colostrum helps build closeness between mother and baby, making caring for the baby go more smoothly.
Changes in breast milk as babies grow help them receive nutrients suited to their bodies' needs at each stage. Breast milk also contains hormones and protective factors that help babies develop a strong immune system. Next, let's look at some things to know about colostrum.
Precautions About Colostrum
Colostrum is highly nutritious and offers many benefits for babies early in life. However, there are some precautions to keep in mind.
Small amounts, but enough for your baby: Only a little colostrum is released at a time, matching a newborn's very small stomach. Mothers therefore do not need to worry about insufficient milk. What matters is breastfeeding frequently, around 8–12 times a day, to help milk come in sooner. If your baby cannot feed, urinates less, develops jaundice, or is unusually drowsy, consult a doctor or a nurse specializing in breastfeeding.
Be aware of the mother's health conditions: Colostrum is linked to substances present in the mother's body, which can affect the baby. Mothers with a contagious illness or a cold can usually continue breastfeeding while washing their hands frequently and wearing a face mask. However, always consult a doctor first, including before taking any medication while breastfeeding.
It naturally changes into regular breast milk: Colostrum gradually changes into transitional milk within a few days after birth. Mothers do not need to express and discard it or save it to use instead of regular breast milk. During this period, do not give your baby plain water, honey, or sweetened drinks, and do not add formula on your own unless a doctor recommends it.
Take care and follow the advice of your medical team or a healthcare professional when feeding colostrum to your baby.
