Re: Wean 10 month old with cold sore?
Yes, if you've ever had a cold sore, you're unlikely to develop sores on your nipples from this exposure. There is *not* a lot of research on this--it came up when my son had his primary breakout. If you were previously uninfected, it could happen (primary infection sometimes occurs at the site of exposure/contact). You can carry HSV1 without being symptomatic, too.
My son had 1-3 cold sores in the course of his four years of nursing. I've had cold sores since very early childhood, so he almost assuredly picked up the virus at some point when I was shedding. The pain can sometimes discourage wee ones from nursing, especially if the first outbreak takes the form of herpes gingivostomatitis. Anyhow, my nipples were and are just fine. I was really worried because OMG, that would hurt.
