Collecting Colostrum: What Lactation Consultants Want You to Know
Collecting Colostrum: What Lactation Consultants Want You to Know
With all the “how to” health advice videos flooding social media feeds, it’s becoming harder to separate fact from fiction. This confusion is especially common when it comes to pregnancy tips—like the increasingly popular practice of harvesting breast milk before birth.
Mother's first milk, medically known as colostrum, is a nutrient-rich substance that starts coming in around the 16th week of pregnancy. In certain cases, health care providers may recommend collecting colostrum before birth.
“Colostrum harvesting is a personal practice that can be helpful for mothers who have struggled to breastfeed their first child,” says Jessica Clayton, RDN, CDN, IBCLC, lactation consultant at University of Utah Health. “However, I encourage parents to reach out to a prenatal lactation specialist for a consultation to make sure this is something they should be doing.”
Myth 1: You Must Collect Colostrum in Abundance
When it comes to social media trends, everything must be done in abundance—and sadly, this pertains to colostrum harvesting. Clayton notes that many of her patients feel overwhelmed by the unrealistic expectations set by influencers who proudly showcase rows of vials. Yet before you start following suit, please be aware of the health risks of excessive colostrum collection.
“Over-collecting can set off hyperlactation, in which milk production exceeds your baby’s needs,” Clayton says. “This misguided approach can also lead to nipple damage, which can be very painful.”
In reality, mothers only need to produce five to seven milliliters (about the size of a teaspoon) of breast milk per feeding within the first 12 to 24 hours. So, contrary to the eight ounces of breast milk recommended by mommy influencers, your baby’s tiny tummy requires just a modest supply until your mature milk typically arrives around day three.

- One Month: Size of a large egg
Myth 2: Colostrum Harvesting Is Vital for High-Risk Pregnancies
Online chatter—largely sparked by a 2019 study—has led many to believe that women with high-risk pregnancies should begin collecting colostrum to prevent future breastfeeding challenges. If that advice makes your blood pressure spike, take heart: the recommendation specifically applies to women with diabetes, not to all high-risk pregnancies.
“This study went viral on TikTok, causing people to think that everyone, especially women with health risks, should be collecting colostrum,” Clayton says. “This recommendation applies specifically to women with diabetes and is not recommended for everyone.”
Myth 3: A Lack of Colostrum Foreshadows Breastfeeding Problems
One of the most persistent myths is that collecting colostrum guarantees an easy breastfeeding journey. This false narrative can sow unnecessary fear and self-doubt, leaving new mothers feeling unprepared.
“If you're unable to collect colostrum, and you're worried you may not produce milk, please know that this is simply untrue,” Clayton says. “Colostrum production does not directly correlate to successful breastfeeding.”
Beyond these three debunked myths, Clayton notes that prenatal health still holds many unanswered questions—largely due to limited research in the field. One area of concern is colostrum collection via pumping, which some practitioners believe could trigger early contractions. While this outcome appears unlikely, Clayton stresses that more evidence is needed to confirm or rule out the risk.
“There is very little evidence that shows using a breast pump causes early contractions due to stimulation,” Clayton says. “But whether you’re using a pump or hand expression, it’s important to see a lactation specialist to learn safe techniques that won’t cause injuries or pain.”
Finding Resources and Support
Clayton encourages expectant parents to connect with their care team early in pregnancy, laying the foundation for a safe and healthy prenatal experience. She takes pride in her work at University of Utah Health, where patients can benefit from a wide network of specialists, education programs, and resources tailored to their unique needs.
“We’ve recently launched an individualized care plan that allows expectant mothers to meet with their lactation team during pregnancy,” Clayton says. “These visits can be requested as part of prenatal care, helping to build a supportive ‘village’ before the baby arrives.”
