DS has a blister right in the middle of his top lip. He is just over 8 months btw. He has been full of cold for the last couple of days also. I am really worried that it is a coldsore?? If it is a coldsore, will I have to stop breastfeeding him? I don't know if I have the heart to express 5 feeds a day I will be so so so upset if something like this stops me BFing him. Didn't know whether to put this is health or feeding, so put in both with the hope of a few responses before the next feed is due!!
