Is this a cold sore on the outside of her lip?We don’t let anyone kiss our baby or touch her on the face, but this looks like a cold sore and has me freaking out. Advice?

*UPDATE* We did call the doctor and left a message with the answering service. The on-call pediatrician called back and said even if it is a cold sore we shouldn’t be worried. We should call back if it starts oozing or spreads. So, I guess nothing to be concerned about.

*SECOND UPDATE* It’s gone today so it wasn’t a cold sore after all.
