My dd 2.5 seems to have a cold sore in the corner of her mouth. She is very under the weather and bad tempered. Could they be related?
What can I do to treat it? DH has always suffered from them, he uses zovirax but don't know if that is suitable for toddlers. Since he has been taking L-Lysine supplement they have vanished though, anyone know if that is suitable for toddlers too?
