So... Sil gets a lot of cold sores...Is it OK to nicely ask her not to share her ice cream with my toddler? I'm sure she wouldn't anyway if she had an active one but I work in the dental field and I know some of us carry the herpes virus in our Saliva without getting coldsores...In addition, if someone is prone to decay or gum disease and shares Saliva with another who isn't this can cause problems for the recipient...
I'm just not at all keen on her sharing saliva laden food with others or utensils but not sure others will understand this let alone respect it?
