I'm not a huge germaphobe, and i'm not asking ALL my loved ones to get TDAP or anything, but my grandma has cold sores and the herpes virus can be deadly to infants. For most of the family, we're taller than she is so we can avoid well intended kisses, but how do I politely keep her from kissing my baby?
Re: How do I politely keep Great Grandma away from the baby?
That being said... I think most people carry the virus that causes cold sores, right? Some people just aren't symptomatic so you never see them with cold sores. I get cold sores and people are so rude about them. I don't have herpes. I've gotten them since I was a kid. There is a huge weird stigma about cold sores!! Unless she has a brand new one, she won't get the baby sick. But I completely understand your fear.
Maybe I'm naive, but I'd think her -- along with everyone else in the family -- would be concerned about keeping baby happy and healthy too.

Actually the two types have combined in the past decade and can be indistinguishable with one transferring to the other. But yes, cold sores ARE caused by the herpes simplex virus, which if passed to an infant can result in swelling of the brain and death.
My grandmother is a slightly senile Hungarian who asks the same question every 5 minutes. She means well, but is usually just irritating. example: my mom has wooden cutting boards and a patinaed copper sink. She soaked the cutting board-warping it- and scoured the patina off the sink (it re-patinas but comes perfectly evenly patinaed) despite my mom repeatedly asking her to stop doing the dishes. Then having my Dad tell his mom to stop doing the dishes. I imagine my husband will also.
I think the "No Kisses" (for anyone) policy may be the best approach...
