I agree that baby acne is NOT caused by breastfeeding. It is usually gone by 6 mos. however. One caveat: mom might check her diet for highly allergenic foods--my son had funny rashes before he was taking much solid food. We later discovered he was allergic to peanuts. The funny rashed stopped when I stopped eating peanut. -- Anne Montgomery, M.D., I.B.C.L.C. [log in to unmask] St.Peter Hospital Family Practice Residency Olympia, WA
