question: I noticed a cold sore on my outer lip on Saturday morning and later that day went to see my friend s 6 week old baby. I held the baby and fed her a bottle. After I left, I realized that my cold sore was worse and completed a google search and realized how dangerous cold sores can be for babies. I m in a panic right now about what to do. Should I call my friend and get her to get her baby checked out, is it likely that she got infected, how long would it take to show symptoms if she was contaminated?
