A new Israeli study suggests exclusive or longer duration of breastfeeding (at least 6 months) can reduce the risk of developmental delays and neurodevelopmental conditions in young children.

Researchers found babies breastfed for at least 6 months were more likely to hit language, motor, and social milestones compared to those breastfed for shorter periods.

Even in families with multiple children, the babies who were breastfed for longer had fewer developmental delays than their siblings.

The study was published by Goldshtein I et al., in JAMA Netw Open. 2025.
