From why I know about BF, breastfeeding does not increase anything, not does it reduce the risk of anything, as it's the absolute biological norm and base from which to build or otherwise. For example, BF does not reduce the precedence of SIDS, FF can increase the risk. I wonder whether that conclusion is again drawn from (GENERALLY) that more educated women BF? Eh, I dropped out of school in year 10, worked in fast food and theatre and have no qualifications, I'm technically the epitome of uneducated on paper, and I BF. It's just broad and statistical, not personal.
