I didn't know it was serious for babies to get it. I don't get cold sores but my daughter does, and I got these polysporin band-aid things for her, so it was at least covered up. Just wash your hands frequently/try not to touch your face and that's about al you can do, I think.

I think the virus can only be spread like on wet surfaces or cracked skin, so if you kissed your baby last night somewhere on her head, I think she will be fine. Even on her mouth, I do feel she will be fine unless there was some open skin. My mom gets cold sores (sorry mom!) and kissed me on the mouth plenty when I was a youngin and I never got them. I would just be a freak about washing your hands, and there is this ointment they sell at whole foods for cold sores that has lysine and zinc and other stuff that really does speed the healing by a few days. Couldn't hurt to up you vit c too. Try to identify foods that aggrivate and cause a flare up.

If a mother gets her first outbreak after delivery and therefore didn't transmit anitbodies that have built up over the years during gestation, then it can be very dangerous for the baby.
As for what you can do, probably nothing more than what you are doing now. Good hygiene is key.
