I know the inconsistancy is a big part of it. She is at the age where she is pushing your limits, and seeing what she can get away with. I would suggest you and your husband figure out a solid disapline standard that you both can follow and once you agree on what that is, the next time she bites, explain to her what is going to happen and FOLLOW THROUGH. You have to do this every time, and soon enough she will know that you aren't going to break on this. It works. Also, I wanted to mention, that I am giving away child safe kits. They keep a record of your daughter's fingerprints and photo, other info, etc. This helps your piece of mind as well, especially if she's as rambuncious as you say. That way if , god forbid, she does get lost or something, you have an ID card that can help anyone find her. If you want one, let me know. Me email is ____@____.com
