Good day! My son is 2 weeks old, I have a cold on my lip. Has anyone had this? I read that it's very dangerous for babies. I immediately smeared all with ointment, the blisters practically didn't come out, and constantly there was a layer of ointment on top. I don't kiss the baby, I constantly wash my hands. Very worried!
