Today a stranger (friend of a friend at a gathering) was holding my almost 7 week old. DS started crying and looking for food. Before I knew it she had sucked on her finger and slipped it into his mouth for him to suck on. Surely this is NOT ok? I felt very uneasy. I did not say anything for two reasons A) in my opinion the damage was done. B) I felt uncomfortable saying something. Am I being over cautious? I am now really worried, I don't know this person or anything about any health issues she could possibly have.
