If you want a smart kid, you might want to consider breastfeeding. In a study of nearly 14,000 children, researchers found a positive link between breastfed babies and high performance on IQ tests at age six. The thing is that it’s hard to tell whether the breast milk itself is causing the IQ test performance scores to be higher, or if it’s related to the bond formed by breastfeeding. Either way, those who breastfed exclusively for at least the first three months scored an average of 5.9 points higher on IQ tests in childhood. [BBC]
