Oh believe me i understand. Your son is not at risk. Hsv2 sheds very little and is rarely an oral infection which also helps. When ever your mom has an outbreak just have her refrain from face to face contact.
Your mother has hsv2 on her nose? If i understand that correctly, your baby is at no risk unless your mom rubbed her nose on him. Your baby isn't at risk ontherwise. On a side note, a lesion that is scabbing usually is not contagious anymore. The healing process usually means the virus has retreated.
