Would it bother you if your LO's daycare teacher had cold sores? Yesterday I noticed that one of LO's teachers has huge cold sores all over her top lip and the sides of her mouth. Naturally I didnt say anything but I heard another parent asking her about it and she said its really painful but she kept saying "I promise not to kiss the kids" which made me a bit worried. I have never had a cold sore but I the other parent said they are very contagious
