Breastfeeding a baby for a year on average could lead to an increase in IQ of about four points, the LA Times reports. In a study recently reported in the Journal of the American Medical Association of Pediatrics, researchers found that there is a "causal relationship of breast-feeding duration with receptive language and verbal and nonverbal intelligence later in life." The study assessed 1,312 mothers from Massachusetts who participated in Project Viva. At age 3, breastfed children did better on a vocabulary test, and at age 7, breastfed children did better on an intelligence test, but no association between breastfeeding and visual motor skills or visual memory was determined. The study's authors concluded that exclusive breastfeeding for the first six months of life and continued breastfeeding through the first year should continue to be recommended to new moms.
