Colostrum: How Much Does a Newborn Need?

Written & Medically Reviewed by Dr. G

Many new mothers see only a few drops of colostrum and immediately wonder: “How can this possibly be enough for my newborn?”

That concern makes sense because colostrum does not look like the larger volumes of milk parents expect later.

It is often thick, sticky, and yellow or golden, although its appearance can vary. And there may not seem to be very much of it.

But that is normal physiology.

CDC notes that there is not a large volume of colostrum at first, yet most healthy babies receive the nutrition they need from it during the first few days.

What Is Colostrum?

Colostrum is the first stage of human milk.

It contains nutrients, protein, antibodies, and other immune components that help support your newborn during the transition to life outside the womb.

Compared with mature milk, colostrum is concentrated and produced in smaller quantities.

Small volume does not mean inadequate milk production. It is exactly what we expect at the beginning of breastfeeding.

How Much Colostrum Does a Newborn Need?

There is no single required amount that every newborn must drink at every feeding.

However, studies summarized by the Academy of Breastfeeding Medicine give us a useful picture of typical early intake.

These ranges show how intake generally increases over the first several days. They are not minimum amounts your baby must achieve at every feeding.

A directly breastfeeding baby may take different amounts from one feeding to the next, which is completely normal.

Why Does My Newborn Need So Little Colostrum at First?

During the first days, your newborn's feeding needs are relatively small, and colostrum is concentrated.

Your baby's appetite and milk intake increase quickly after birth. At the same time, frequent sucking provides the breast stimulation that helps milk production increase.

This is why frequent breastfeeding is more important than trying to make every early feeding produce a particular number of milliliters.

How Often Should a Newborn Breastfeed for Colostrum?

Newborns usually feed frequently.

During the first days, many babies breastfeed about every 1 to 3 hours. Over 24 hours, most breastfed newborns feed about 8 to 12 times.

I'm Only Seeing Drops of Colostrum. Is That Normal?

Often, yes.

Colostrum may initially appear as drops rather than ounces. The amount normally increases as lactation progresses.

A small amount obtained from a pump does not automatically mean your baby is receiving too little.

Hand expression can also be especially useful during the early colostrum period, when the volumes are tiny.

When Does Colostrum Turn Into Mature Breast Milk?

Colostrum is already breast milk—it is simply the first stage.

Over the first several days, milk volume increases and the milk transitions from colostrum toward transitional milk and later mature milk.

HealthyChildren notes that the noticeable increase often called milk “coming in” commonly occurs about 2 to 5 days after birth.

How Do I Know If My Baby Is Getting Enough Colostrum?

This is where we want to look at the baby instead of trying to measure every drop of milk.

Reassuring signs include:

• frequent feeding,
• visible or audible swallowing,
• increasing wet diapers,
• stool changing away from dark meconium,
• a baby who is alert enough to feed effectively, and
• a reassuring weight trend.

Does My Baby Need Formula Because I Am Only Making Colostrum?

No—not simply because your breasts are producing colostrum.

Colostrum is the normal milk expected during the first days, and most healthy full-term babies can meet their early nutritional needs through breastfeeding.

But some babies do need supplemental feeding for medical reasons.

Reasons for evaluation may include:

• ineffective milk transfer,
• concerning weight loss,
• dehydration,
• hypoglycemia or significant risk for low blood glucose,
• worsening jaundice associated with inadequate intake,
• prematurity, or
• another medical condition.

Supplementation decisions should be based on your baby's clinical situation, not simply on the fact that you can express only a few milliliters.

Is 5 mL of Colostrum Enough?

It can be a completely normal amount during an early feeding.

For example, during the first 24 hours, 5 mL falls within the approximate 2–10 mL intake range reported in studies of healthy breastfed newborns.

But this is exactly why the ranges should not be treated as a feeding prescription. One feeding of 5 mL cannot tell us whether your baby is getting enough across an entire day.

Feeding frequency, swallowing, diaper output, weight, and clinical condition provide a much better answer.

Is 10 mL of Colostrum Enough?

During the first day, 10 mL can also fall within reported physiologic intake ranges.

As your baby gets older over the next several days, expected intake generally rises.

Again, the goal is not to make your newborn hit a fixed number at each feeding.

What If My Baby Has Trouble Latching Onto the Breast?

A baby who cannot latch effectively may not remove colostrum well even when your breasts are producing an appropriate amount.

Correcting the latch therefore matters more than simply trying to produce more milk.

What If My Baby Is Too Sleepy to Take Colostrum?

Some sleepiness during the first days is common.

But a newborn who repeatedly cannot wake enough to feed effectively deserves closer attention.

Try:

• skin-to-skin contact,
• changing the diaper,
• gently stimulating the feet or back, and
• offering the breast when your baby begins stirring.

If your baby consistently cannot remain awake long enough to feed or you are not seeing evidence of milk transfer, contact your baby's healthcare team.
