I have a 9-month-old who interacts with my mother quite closely. My mother has a partner who regularly gets cold sores. Although my mother has never presented with a lesion, I know it’s possible that she may carry the virus asymptotically, and can at any point be “shedding” the virus (am I correct in believeing this?). For this reason, I’ve asked her not to kiss my baby. She’s taken offence to this (as she believes that she doesn’t carry the virus due to her never having had a lesion), and I suppose I’d like to know whether people feel I’m being unreasonable? Also, if not, is there any way of protecting my baby, should my mum ever slip up and kiss him?
