I got wonderful advice from a friend who is a child psychologist.
When she bites you, you have to startle her ( to get her to associate biting with an unpleasant experience)
Yelp, (like a puppy would) and scold, "No biting Mommy! That hurts!" and walk away.
She will cry and seem very distraught. After a moment or two, ( not long at all) go back and comfort her, offering a chewable item (like a frozen washcloth) and in a soothing tone repeat "It hurts when you bite. That's not OK" Do this consistently every time, and the behavior should disappear very soon.
Do you see a pattern when she bites? Is she tired, frustrated, fussy, etc? If so, you can anticipate the behavior and head it off...
I had this problem with my daughter too, and by 11 months, she was totally weaned onto a cup. I think that she felt frustrated because she wanted to nurse, but she also wanted to roam, and was dealing with the fact that ... well.. you can't take it with you... So she'd bite while nursing out of frustration for being held "captive", but then bite because she was frustrated that she wasn't nursing!
It gets easier when they begin to talk and you can teach them emotional language so they can express their feelings. Until then, you have to be aware of the non-verbal signals your daughter is putting out, and try to anticipate her moods..
Good luck, and I hope the biting stops soon.
