My BM is salty tasting and a little slimy?

What do you mean that your baby doesn't like the milk after let down? How old is the baby? How long does he nurse for? What does he act like when you think the taste of the milk changes? Is he still hungry at this time? Do you feed him more? Do you know that you have many let downs during a feeding and not just one? It can be normal for breastmilk to taste salty. What symptoms do you have that would make you think that you have mastitis - you don't have any clogged milk ducts - do you have any redness, warmth, tender to touch areas of the breast or - fever, chills (flu like symptoms)?
