You're friend would have been contagious. We had a similar situation here with DD being held by a friend who found out she had chicken pox 2 or 3 days later. DD was 9 weeks old and she never caught them, maybe she was just lucky though . But honestly hun, I came to the conclusion after worrying myself sick, that if she was going to get them off our friend then we couldnt turn back time and change anything so we just had to cross that bridge when and if we got to it. your little Miss is ok
