Recently this story made the rounds:
Breastfeeding your baby could help them achieve academic success by the age of 10, a study has found.

A recently published Australian study on the impact of early breastfeeding on school test performance at age 10 captured the interest of the media, but the most important results for educators (& the public) were typically not included in these reports...
Inspection of their data shows, however, that other predictors were much more powerful, including family income, mother's education, and whether the mother and child read together when the child was five years old. Family income and mother's education are related to access to books in the home, school and community (Krashen, 2004).
These results are very important for educators. They are a strong confirmation that access to books and reading to and with children are powerful means of insuring high levels of literacy, a commonsense view that is well supported by previous research (Krashen, 2004) but nearly completely ignored by policymakers.
Of interest to educators is how much breastfeeding added to the power of income, mother's education, and reading together in predicting test scores. Unfortunately, the authors did not perform a hierarchical analysis, but looking at their results (table 4), my guess is that it did not count for much. http://www.substancenews.net/articles.php?page=1885§ion=Article
