S.H.
Ooooh... I had a biter, too. She hasn't picked up on piching yet, thank goodness. I tried telling her no firmly even in desperation tried smacking her a little when she did it. I asked the doctor about it and what she told me worked VERY well. She said that when my daughter bit me to say "no bite" firmly, put her down and walk away. The bigger problem was her biting other kids. When she did THAT I had to tell her "no bite" firmly and pick up the *other* kid and show them love. She HATED that and the biting stopped really quickly!! I hope whatever you try works for you. This worked great for mine!
