My DD1 is also born march 06 and we have a very similar issue that has intensified since DD2 has come along. In the last few days i have not responded to her biting at all- no neg or pos feedback, i dont even look at her when she bites me so she get no acknowledgement (it's hard to ignore esp if she is hurting me) and yesterday and today she will go to bite me but will not actually bite down iykwim. Its like she is waiting for me to say something but if i just carry on whatever i'm doing she finds something else to do. I am thinking in another day or so she will think why bother ?? well i'm hoping
