I'll reply to the list, too, because there hasn't been many responses yet. No research here, just my experience. My 3rd child, when 9 months became very sick, was put on antibiotics, to which he was allergic (got that 'ceclor rash - but I thought he had german measles). Discontinued any medicine when we discovered it was a cold sore in his mouth. That was roughly 3-4 days after this all started. I have had cold sores all my life around my mouth, never on breast. I didn't develop any signs or issues there whatsoever then, up to now. That was almost 10 years ago. Poor baby was so sick (primary outbreaks are brutal!) but never had a nursing strike during it. I was impressed :-) He was also the child who(not many months later) would nurse for an hour straight while I had the Norwalk virus. It hit everyone in the house except him. He was even vomitted on by an older brother - but my Luke never got sick. I love breastmilk :-)) Keep us posted, Cordelia.
