After examining a survey of 7500 children, researchers suggest that breastfeeding does not contribute to a child’s school readiness.
There is evidence that breastfeeding for three months or more is positively associated with a child’s reading skills. However, this association seems to be because mothers who breastfeed are often more educated and exhibit behaviors that support a child’s cognitive development. Instead of breastfeeding, reading to a child and being sensitive and supportive of a child’s development were more likely to predict a child’s success in math and reading.
While these researchers concede that breastfeeding aids development in other ways, they suggest that parental behaviors that support a child’s development are a more direct way of preparing the child for school.
