E.G.
1. It's no disgrace to get counseling just to help yourself through this and to know you've been proactive.
2. My best guess, from this distance, as to what is going on is that your daughter loves you, and feels safe with you, and that you are the complaint department. Biting at this age is often the result of knowing that communication happens with the mouth, somehow, but not being able to use words. So you get bites and screams. Especially if she's not talking yet, that's probably what she's trying to tell you - 'mom! I can't make anyone understand me! You're may last hope here, mom, you get it more often than anyone else! Help!' Does this sound right? If so, don't let her bite you (no need to get rough, just evade and say 'no') and if you think you know what the problem might be at any time, try talking for her 'you're sad because Grandma's leaving' or 'playing is more fun than getting changed'. See if this helps. Good luck, and most likely, this too shall pass. And odd as it seems, this behavior probably does not mean that she doesn't like you!
