Study: Breast-Fed Babies Are Smarter

Score better on intelligence tests later in life.

Say goodbye to the formula once and for all. Babies who are breast-fed grow up to score higher on intelligence tests, according to a new study. The study, which examined more than 1,300 moms and their babies, supports that new moms could be boosting the IQs of their children just by one simple decision. With each added month of breast-feeding, there was a 0.3-point increase in intelligence by age 3 and a 0.5-point increase by age 7. Researchers made sure to also include outside factors that tend to lead to intelligence—access from parents that has to do with income, employment, and education—and the benefit was greatest when babies were breast-fed “exclusively for the first six months.”
