Can we re-visit this topic? The archives was truly overwhelming! My reason for asking is, I'm writing a breastfeeding management article for our staff entitled "Finish the First Breast First". The Woolridge and Fisher article in the Lancet, August 13, 1988 states ... "The protein and lactose concentrations in human milk remain fairly constant during a feed, whereas the fat concentration of breast milk rises consistently throughout (though individual feeds may not conform entirely.) My question, or at least, what I thought was correct ... That there was higher concentrations of protein and lactose in foremilk. Is it that the difference is that there is a higher quantity of foremilk that contains less fat and that hindmilk contains the same amounts of protein and lactose as foremilk but is less in quantity and higher in fat? Thanks for your help and your patience. Camille in Jackson, Mississippi, in southern USA.
