Cold sore and 5 week old baby

Marielle
Help! I had couple of cold sores pop up a couple of days ago. I've always had them and even got some while pregnant. My LO is currently 5 weeks old and I was wondering if I could have transferred itnover to him? I haven't kissed him on the mouth or even anywhere on his body since I felt the tingle just to be on the safe side. I noticed this morning that he has this spot on his upper lip. It kind of looks like baby acne but not too sure.
