We all know that breastfeeding is good for baby, with recent studies finding all kinds of new benefits. However, there has long been a debate about how long an infant should be breastfed for. While many experts agree that the ideal time-frame is around six to eight months, a new study has found that babies who are breastfed for at least twelve months tend to have a higher IQ.
Dr. Bernardo Lessa Horta, of the Federal University of Pelotas in Brazil, and lead author of the study followed the group of over 3,500 infants for over thirty years. Horta said that the study provided the very first evidence that breastfeeding for a more prolonged period of time increases intelligence until at least thirty years old. The study also found that prolonged breastfeeding had an impact on individual and societal levels by increasing the odds of improving educational attainment and even their earning potential.
