A Scottish study has shown that contrary to the prevailing wisdom, breast feeding does not have any direct correlation with the intelligence of your child. The research included looking at siblings who had been bottle-fed as compared to breast-fed.
What they did determine was that intelligent women were more likely to breast feed, which in turn means that their babies are more likely to be intelligent through their genetic stock.
The researchers emphasised that breast-feeding still rocks for any number of other reasons like nutrition, antibodies, not getting fat and lower cholesterol and blood pressure later in life. It just means that intelligence may no longer be one of them.
This research doesn't change of the World Health Organisation breastfeeding recommendations.
