Briefly about colostrum
- Colostrum is the first maternal milk, produced from the end of pregnancy and during the first days after birth.
- Its small volume corresponds to the newborn’s small gastric capacity, often between 5 and 10 milliliters on the first day.
- Highly concentrated in antibodies, proteins, and protective factors, it supports the baby’s immunity and digestive adaptation.
- A milk supply usually occurs between the 2nd and 5th day, with great variability depending on the birth, frequency of feedings, and parental health status.
- Some drops can be expressed by hand when breastfeeding is delayed, after a difficult birth, or a temporary separation.
Colostrum and baby’s first days, understanding this first maternal milk
Colostrum is the first maternal milk received by the baby after birth. It is already present in the breasts during pregnancy, usually from the third trimester. Some women notice a few thick drops, yellow or orange, as early as the fourth month. Others never see any before delivery. The absence of discharge during pregnancy neither predicts a lack of colostrum nor future breastfeeding difficulties.
Its color ranges from golden yellow to cream, sometimes almost transparent. Beta-carotene, a precursor of vitamin A, often explains its warm hue. Its texture is denser than mature milk because it contains little water and a high concentration of active components. This appearance can be surprising when expecting a white, fluid milk. Yet it corresponds exactly to the needs of the first hours.
The volume produced is modest. About 25 to 50 milliliters over the entire first day is a usual range, spread over many feedings. On the first day, a newborn’s stomach is very small. Therefore, they do not demand large bottles or large volumes of milk. Frequent feedings, often between 8 and 12 times in 24 hours, allow the baby to receive this concentrated liquid while progressively stimulating milk production.
Colostrum production is linked to pregnancy hormones. After the expulsion of the placenta, the rapid drop of progesterone allows prolactin to act more fully on the mammary gland. The breast then gradually shifts toward greater production. The baby’s sucking, skin-to-skin contact, and regular feedings support this process. Cesarean birth, hemorrhage, maternal diabetes, or medical separation can sometimes delay this transition but do not mean it will fail.
The first breastfeeding can take place within the hour following birth if the parent’s and baby’s health allow. Skin-to-skin contact maintained for at least an hour helps the newborn stabilize temperature, breathing, and blood sugar. It also promotes feeding awakening behaviors. The baby turns their head, opens their mouth, brings their hands to their mouth, and sometimes slowly moves toward the breast. This time does not need to be perfectly organized to be useful.
A premature baby receives colostrum especially tailored to their gestational age. Its composition notably includes more of certain protective elements. When sucking is not yet possible or would tire the child too much, early manual expression allows collection of drops in a small spoon, a sterile syringe, or a container adapted to the protocol of the service. The very small quantities obtained are not insignificant. Each milliliter is dense nutritionally and immunologically protective.
The first hours can be disorienting when the baby sleeps a lot or suckles irregularly. A healthy newborn can have an intense awakening period after delivery, then sleep more deeply. Vigilance is less about a precise feeding duration and more about all observable signs. A wide-open mouth, slow sucks with audible swallows, increasing wet diapers, and a baby waking to feed provide more reliable indicators than a stopwatch.
The benefits of colostrum for immunity, digestion, and newborn health
Colostrum doesn’t just nourish the baby. It also helps protect them as they leave a highly protected intrauterine environment to face microbes in the outside world. Its richness in immunoglobulins, especially secretory IgA, forms a protective layer on the mucous membranes of the mouth, respiratory tract, and intestine. These antibodies do not replace the baby’s immune system, which is still immature, but help them get through this adaptation period.
Colostrum antibodies act mainly on the surface of the intestine and mucous membranes, where the newborn encounters their first microorganisms. This local protection makes sense in an infant whose digestion and immunity are still developing. Breast milk also provides white blood cells, enzymes, lactoferrin, and oligosaccharides. The latter do not only serve as food; they nourish certain beneficial intestinal microbiota bacteria and limit the colonization of several undesirable germs.
Proteins are particularly concentrated in this first milk. They are present at a higher level than in mature milk, often described as about two to three times higher depending on comparisons and periods analyzed. These proteins are not only for tissue growth; several have defense or digestive maturation functions. This composition meets the needs of a baby who requires small energetic quantities but high biological density.
Colostrum also helps the elimination of meconium, those first thick, very dark, sticky stools. Early feedings stimulate intestinal transit. Meconium evacuation helps reduce bilirubin reabsorption by the intestine, which may help limit the risk of neonatal jaundice. Mild jaundice is common in the first days. However, it deserves monitoring because jaundice that worsens, appears very early, or accompanies a baby who is difficult to awaken requires medical advice.
The notion of “small quantity” often causes concern. Parents see a few drops and fear the baby gets nothing. Yet the volume is adapted to newborn physiology. Giving supplements without medical indication can space out feedings and reduce breast stimulation. In some situations, a supplement is necessary and can protect the baby’s health. The decision is then based on concrete data such as significant weight loss, hypoglycemia, dehydration, or insufficient sucking assessed by a professional.
The protection offered by colostrum does not make the baby invulnerable. It is a valuable aid among other health measures. Hand washing, limiting contact with sick people, attending screening appointments, and vaccination according to the current schedule remain complementary. Breast milk then evolves throughout the entire duration of breastfeeding, but the first days offer a concentration especially suited to birth.
Colostrum does not need to be abundant to be useful. A few repeated drops correspond to the physiological rhythm of a newborn, whose stomach and sucking capacities are still organizing.
Babies who receive colostrum do not all have the same rhythm, vigor, or support needs. Premature birth, a restrictive oral tie, significant breast pain, or major maternal fatigue can complicate the start. These situations deserve careful observation rather than comparison with other infants. The benefits of colostrum also show when its collection requires appropriate technical support.
Immune protection continues afterwards with transitional milk. The following days mainly require observing how the baby actually transfers milk and how their body adapts to this new feeding.
From colostrum to mature milk, concrete markers on milk supply and nutrition
The transition between colostrum and mature milk is gradual. It is not like a switch suddenly flipping. Between the second and fifth day after birth, many parents feel a clear increase in volume produced. Breasts become heavier, warmer, or firmer. Milk then often takes on a creamy or whitish color. This phase is called transitional milk.
Around the fifteenth day, milk is generally considered mature. It remains living and variable. Its composition changes during a single feeding, between day and night, depending on the baby’s age, and sometimes in response to an infection encountered by the family. This evolution is not a sign of instability. It reflects the continuous adaptation of breastfeeding to the infant’s growth and health needs.
| Period after birth | Dominant milk type | Observable markers | What supports production |
|---|---|---|---|
| Days 1 to 3 | Colostrum | Small volumes, frequent feedings, first dark stools | Skin-to-skin, breastfeeding at the first signs of awakening, manual expression if needed |
| Days 2 to 5 | Transitional milk | Fuller breasts, stools progressively lightening | 8 to 12 daily stimulations, comfortable and effective breastfeeding |
| From about 15 days | Mature milk | Baby’s own rhythm, regular wet diapers, monitored growth | Demand feeding and support in case of pain or doubt |
An effective feeding in a newborn often lasts between 10 and 20 minutes per breast, but this range should not become a strict rule. Some babies take a lot of milk quickly. Others need breaks, especially during the first days. Observing swallowing is more telling. After rapid sucks at the start, jaw movement becomes broad and regular. The chin lowers for a long time and a swallow can be heard or seen.
Hunger signs generally precede crying. The baby fusses, moves lips, turns head toward contact, sticks out tongue, or brings hands to mouth. Offering the breast at this moment often facilitates latch. A crying newborn is not being capricious. Their nervous system is immature, and crying is their way of signaling hunger, discomfort, fatigue, or need for closeness. Responding to these signals builds security, not dependency.
Diaper frequency provides another simple marker. During the first days, the number of urinations gradually increases. From the fifth day, at least five to six well-wetted diapers over 24 hours are often expected, with yellow stools in breastfed babies. Color and quantity must be interpreted with the baby’s exact age, as meconium is normal for the first days.
Weight loss almost always occurs after birth. This corresponds notably to the elimination of fluids accumulated during pregnancy. Monitoring is necessary if loss approaches or exceeds 10% of birth weight, continues beyond the first days, or the baby does not gradually regain weight. Weight tracking combined with clinical examination and observing a feeding gives a more reliable picture than a single isolated number.
Inverted or flat nipples do not necessarily prevent breastfeeding. The baby takes a large part of the areola, not only the nipple. A stable position, the baby’s tummy against the parent’s body, and a widely open mouth often make the difference. Detailed guidelines are available on breastfeeding with inverted nipples, especially when latching remains difficult after several attempts.
Giving colostrum when the first feeding is difficult or delayed
The first breastfeeding does not always happen immediately after birth. Cesarean section, neonatal care, prematurity, major fatigue after a long delivery, or medical issues can create a temporary separation. This situation is often emotionally hard. It does not automatically deprive the baby of the benefits of the first milk. Manual expression is often the best technique during the first 24 to 48 hours because the volume is low and drops are thick.
In the first days, expressing a few drops of colostrum by hand can be more effective than a breast pump to collect this thick liquid. The gesture consists of placing the thumb and index finger about two or three centimeters behind the nipple, forming a C. The fingers gently push toward the chest wall, then come closer without pulling on the nipple. The movement is repeated while slightly changing zones around the areola.
Colostrum may take a few minutes to appear. A calm environment, a photo of the baby, their blanket, or some skin-to-skin when possible can help trigger the let-down reflex by supporting oxytocin. Pressure should not be painful. When no drops appear, it is better to be accompanied by a midwife, nursery nurse, or lactation consultant rather than repeating uncomfortable gestures.
- Settle with your back supported and a clean container within reach because the first drops can be collected one by one.
- Gently massage the breast for one minute without rubbing the skin vigorously or pinching the nipple.
- Place the hand in a C shape behind the areola, then press backward before bringing the fingers closer.
- Collect the drops according to the birth facility’s instructions and give them to the baby with the equipment recommended by the team.
Giving only colostrum during the first hours is possible, including if breastfeeding will not be continued. This decision belongs to the parents. The choice to breastfeed, express milk, give infant formula, or combine several solutions does not define the quality of the bond with the baby. Care consists of feeding the child safely, in a way adapted to their condition and sustainable for their family.
When sucking is ineffective, a concrete cause must be sought. A very drowsy baby after certain medications received during labor may need more time. An unstable position, significant pain, a mouth that opens little, or a tense body can hinder latching. A restrictive tongue tie is not diagnosed by appearance alone. It is suspected when persistent pain, insufficient weight gain, or limited milk transfer occur despite position support.
A feeding that hurts beyond the first seconds deserves correction. Pain is not a mandatory step of breastfeeding. Gently detaching the baby by sliding a clean finger into the corner of their mouth, then reattaching with the nose facing the nipple and the chin first against the breast, often helps achieve a deeper latch. If cracks, bleeding, or pain persist, a professional trained in breastfeeding can observe the entire feeding.
Another difficulty occurs when the baby receives a medically indicated supplement. The breast can still be offered first if the child’s condition allows. Regular expression protects breast stimulation while the team monitors hydration, weight, or blood sugar. Decisions sometimes change from day to day. The goal is not to follow an ideal scenario but to meet the baby’s real needs.
The start of breastfeeding is rarely measured by the ease of the first attempt. It builds on repeated observations, concrete adjustments, and help available when needed.
When to seek advice for colostrum, breastfeeding, and baby’s weight gain
The first days often come with doubts that do not necessarily signal an emergency. Soft breasts, many feedings, or a baby who demands again shortly after feeding can be compatible with a normal start. The breast is not a transparent bottle. The volume taken is not immediately visible. The baby’s general condition, diaper evolution, weight, and feeding observation are elements allowing a serious assessment.
A prompt consultation with a midwife, pediatrician, nursery nurse, or lactation consultant is indicated when the baby does not wake to feed, refuses several consecutive feedings, or seems too weak to suckle. Breathing difficulties, bluish or gray coloring, a rectal temperature equal to or above 38°C in an infant under three months, or a temperature below 36°C require urgent medical advice. These signs should not be attributed to colostrum or a simple lack of milk.
Particular vigilance is also necessary if urination remains rare, the mouth appears very dry, fontanelles seem sunken, or stools do not progressively change color after the first days. Jaundice that extends clearly to the belly and legs, a baby difficult to awaken, or weak feedings require same-day evaluation. Jaundice is common, but its intensity and evolution must be assessed by a professional.
On the parent’s side, localized pain with redness, fever, chills, or flu-like feeling may indicate breast inflammation or mastitis. Prompt consultation allows evaluation. Very firm breasts during milk supply can also make latching difficult. Manual areola softening, expressing a few drops before feeding, and frequent feedings can help. Pain that prevents feeding the baby should not be endured alone.
Psychological support is as important as technique. The first days are traversed by hormonal drops, lack of sleep, and great emotional intensity. Baby blues often appears between the third and fifth day after birth and usually eases within two weeks. Persistent sadness, overwhelming anxiety, inability to sleep even when the baby sleeps, thoughts of hurting oneself or the baby require medical support without delay.
Reliable resources prevent searching for contradictory answers in the middle of the night. This guide dedicated to the benefits of colostrum can complement initial markers but does not replace examination of a baby who seems different from usual behavior. Postnatal follow-up precisely allows adjustment of feeding before fatigue or worry sets in.
Colostrum offers the newborn concentrated nutrition and immune support adapted to their beginnings. Parents do not need to prove their body produces enough by watching the expressed quantity. Concrete signs from the baby, support received, and time given to this transition provide much fairer markers.
Is colostrum present before delivery?
Yes. It is produced during pregnancy, most often in the third trimester. Some people notice discharge as early as the fourth month, while others see no drops before birth. Both situations are common.
How long does colostrum last after birth?
It usually dominates during the first two to four days. It then gradually gives way to transitional milk, then mature milk around the second postpartum week.
Can colostrum be given without continuing breastfeeding?
Yes. Colostrum can be offered during the first hours or days, then feeding can evolve toward infant formula if that is the parental choice or if the medical situation requires it.
Why does the baby often demand feeding when colostrum seems scarce?
The baby’s stomach is very small and colostrum is very concentrated. Frequent feedings meet their needs, support hydration, and stimulate the transition to more abundant milk production.
When does a decrease in wet diapers require advice?
A significant decrease in urination, almost dry diapers, dry mouth, a baby who is hard to wake, or weak feedings require prompt advice from a midwife, pediatrician, or care service depending on the baby’s general condition.
