The largest randomized study of breastfeeding ever conducted reports that breastfeeding raises children's IQs and improves their academic performance, a McGill researcher and his team have found.

In a new article, Dr. Michael Kramer reports the results from following the same group of 14,000 children for 6.5 years.

"Our study provides the strongest evidence to date that prolonged and exclusive breastfeeding makes kids smarter," said Kramer, a Professor of Pediatrics and of Epidemiology & Biostatistics in the McGill University Faculty of Medicine and lead investigator in the study.

There you go; traditional motherhood makes our children smarter. Apart from this recent study, children obviously need loving and caring parents who show them affection and moral guidance. It's the basis for the kind of stable, traditional society that's been the foundation to all great civilizations in history.
