Breastfeeding Myths in Early Postnatal Care: Evidence Challenges Routine Practices

Breastfeeding myths continue to influence clinical practice during the critical first days after birth, despite growing evidence supporting a different approach. A new international review published in the Journal of Maternal-Fetal & Neonatal Medicine highlights that several long-standing beliefs regarding colostrum, pacifier use, and early breast pump introduction are not supported by current research. Released during World Breastfeeding Week (August 1–7), the findings encourage healthcare professionals to align postnatal care with the latest evidence and provide consistent guidance to new parents.

Researchers from Sapienza University of Rome reviewed 78 studies, including randomized controlled trials, systematic reviews, meta-analyses, and observational studies from multiple countries. Their analysis focused on breastfeeding practices during the first 48–72 hours postpartum, a period that plays a significant role in successful breastfeeding initiation.

What Does the Evidence Say About Common Breastfeeding Myths?

One of the most persistent breastfeeding myths is that colostrum does not provide enough nutrition for newborns. However, the review found that colostrum production naturally matches the stomach capacity and nutritional needs of healthy full-term infants. Concerns about insufficient milk supply often arise from unrealistic expectations rather than actual physiological limitations.

The researchers note that formula supplementation remains appropriate when medically necessary. However, unnecessary supplementation can reduce breast stimulation, lower milk production, and contribute to earlier breastfeeding discontinuation.

Another widely held belief involves pacifier use. Earlier recommendations discouraged pacifiers because of concerns that they might interfere with breastfeeding. According to the evidence reviewed, pacifier use among healthy full-term infants does not reduce breastfeeding exclusivity or duration. Instead of blanket restrictions, clinicians should provide balanced counseling that supports informed parental decision-making.

How Should Early Postnatal Care Support Breastfeeding?

The review also questions the routine introduction of electric breast pumps during the first few days after birth. Although breast pumps remain valuable in specific clinical situations such as mother-infant separation or poor latch, researchers found little evidence supporting their routine use immediately after delivery. Early pump use may unintentionally reinforce maternal concerns about low milk supply.

When milk expression becomes necessary, hand expression is recommended as the preferred first-line approach during the early postpartum period.

To strengthen breastfeeding outcomes, the authors recommend five evidence-based priorities for healthy full-term infants:

• Educate parents prenatally about normal colostrum volumes and newborn feeding physiology.
• Encourage hand expression before introducing breast pumps.
• Use standardized criteria for medically indicated formula supplementation.
• Replace routine pacifier restrictions with evidence-based counseling.
• Provide access to trained lactation professionals within the first 48 hours after birth.

Evidence-Based Breastfeeding Support Can Improve Clinical Practice

The review emphasizes that these recommendations complement existing WHO guidance promoting exclusive breastfeeding for the first six months. Rather than changing breastfeeding goals, the findings address misconceptions that may interfere with successful breastfeeding initiation.

For obstetricians, pediatricians, neonatologists, nurses, lactation consultants, and primary care clinicians, the review reinforces the importance of evidence-based communication during the earliest postpartum period. Consistent counseling, appropriate clinical decision-making, and individualized lactation support may improve breastfeeding confidence while reducing unnecessary interventions.
