Breast milk boosts brain development in babies by up to 30 per cent, according to a new study.
Children exclusively fed breast milk for at least three months have up to 30 per cent extra growth in the key parts of the brain which control language, emotion, and understanding, say scientists.
The study of kids under four-years-old showed children who have breast milk as part of their diet have a clear advantage when it comes to brain development.
Research carried out at Brown University, in the US, found that by the time the babies had reached their second birthday a discernible difference could be seen in their brain structure.
Dr Sean Deoni, an engineering professor and lead author, said: "We're finding the difference [in white matter growth] is in the order of 20 to 30 per cent, comparing the breastfed and the non-breastfed kids."
