Breast-feeding infants for at least six months appears to give kids' an advantage in school, according to a study published Monday in the journal Pediatrics.
Many other studies have also found a small effect on school performance from breast-feeding. This study, however, was unique in that boys appeared to benefit the most. The researchers, from the University of Western Australia in Perth, have followed 2,868 children since the early '90s. The study showed that, at age 10, boys who were breast-fed for six months or longer scored higher in math, reading and spelling compared with boys who were breast-fed for less than six months. Girls who were breast-fed for at least six months showed a small improvement in reading. The researchers controlled for other factors that could influence school performance, such as family income and education and how often the child was read to.
