Breastfed children perform better in school exams.
An Oxford study has concluded that children who are breastfed are twice as likely to go on and achieve top grades in their GCSE exams.
Researchers analysed the data from nearly 5,000 pupils in England born between 2000 and 2002 and found that performance in GCSEs, taken at the age of 16, increased incrementally the longer the children's mothers had breastfed them.
The study's authors have theorised that the nutrients in breast milk boost brain development.
The connection between breastfeeding and high grades remained even when experts took other factors such as socio-economic background into account.
Renee Pereyra-Ellis, lead author of the research from the Nuffield Department of Population Health, said: "Breastfeeding should continue to be encouraged, when possible, as potential improvements in academic achievement constitute only one of its potential benefits."
