Why breastfed babies are so smart: Moms who breastfeed are often responsive and read to their babies

Research has shown that children who were breastfed score higher on IQ tests and perform better in school, but the reason why remained unclear. Now a new study shows that two parenting skills deserve the credit. Responsiveness to children's emotional cues boosts kids' math and reading skills. Reading to children as early as 9 months of age also significantly improves school readiness. These two skills can give kids an extra 2-3 months' worth of brain development.
