12mo has taken to pinching my neck when I hold her. She's doing it completely absentmindedly, I don't think she even knows she's doing it, but I'm starting to look like an extra out of True Blood. She's got no concept of 'no' yet and doesn't even really seem to get different tones of voice (i.e. stern) so I don't think that will work, and I'm not entirely sure putting her down and walking away will help either - we currently do that for deliberate biting etc., not that it is quite working yet.
Any suggestions, before DP gets too many weird looks for 'giving me' love bites?
