Children who are breastfed for longer periods of time during infancy experience fewer developmental delays and a reduced risk of neurodevelopmental conditions, including disorders like autism and ADHD, acording to new research. The study led by scientists at the KI Research Institute in Israel confirms what many parents might hope to hear: breastfeeding babies for at least six months appears to boost their developmental outcomes.
While health organizations have recommended breastfeeding for the first six months of life for years, this study offers particularly strong evidence by addressing problems that weakened earlier research on the topic.
Published in JAMA Network Open, the study involved health data from 570,532 Israeli children, including nearly 38,000 sibling pairs. It ranks among the largest investigations into breastfeeding and development ever conducted.
Led Dr. Inbal Goldshtein and Dr. Yair Sadaka, the research team used an innovative approach to ensure their findings were reliable. The study uniquely combined routine developmental checkup records from Israel’s maternal-child health clinics with national insurance disability data, allowing researchers to track both developmental milestone achievement and diagnosed conditions.
They compared siblings within the same families who had different breastfeeding experiences but shared genes and home environment. This clever design controlled for family factors like parental intelligence and involvement that often confuse results in other studies.
Children exclusively breastfed for at least six months had 27% lower odds of developmental delays compared to those breastfed for shorter periods. Even children who received both breast milk and formula for six months or more showed a 14% reduction. When examining siblings with different breastfeeding histories, those who breastfed longer had 9% lower odds of milestone delays and 27% lower odds of neurodevelopmental conditions compared to siblings who breastfed for shorter periods or not at all.
The benefits remained clear even after accounting for numerous factors, including pregnancy duration, birth weight, maternal education, family income, and postpartum depression.
The advantages appeared most notable in language and social development—crucial areas for school success and forming friendships. Motor skills improved too, though less dramatically. Premature babies, who typically face higher developmental risks, seemed to benefit even more from extended breastfeeding than full-term infants.
For parents struggling with breastfeeding choices, there’s reassuring news. When researchers specifically examined siblings who both breastfed for at least six months—one exclusively on breast milk and one receiving some formula—exclusive breastfeeding didn’t show a meaningful additional advantage. This indicates that maintaining some breastfeeding for longer might matter more than avoiding formula completely.
The study’s authors believe that their findings should inform public health policies and support systems rather than pressure individual families. Their goal remains helping children reach their potential, not creating guilt among parents facing breastfeeding challenges.
Researchers emphasize that while breastfeeding is linked to better development, it’s just one of many factors that shape a child’s growth. They noted that identifying changeable factors like nutrition is essential to helping each child reach their potential.
Despite expert recommendations, actual breastfeeding rates often fall below targets. Many mothers struggle to balance breastfeeding with work demands, inadequate parental leave, and aggressive formula marketing.
Formula companies spend around $55 billion yearly promoting their products, sometimes undermining women’s confidence in their ability to breastfeed. The authors advocate for stronger supportive policies, including better parental leave and limits on formula marketing practices.
The biological mechanism for these benefits may relate to breast milk’s effects on brain development. Earlier research has shown differences in brain structure between breastfed and formula-fed babies. Some scientists believe these benefits might work through effects on the infant’s gut microbiome, which connects to brain development through what’s known as the gut-brain axis.
As the researchers conclude, these results may help guide not only parents but also public health initiatives aimed at giving children the best developmental start possible. When every advantage counts for our children, supporting breastfeeding appears to be a worthwhile investment.
