DS9 and DD6 fight all the time, like all siblings. Sometime, mean words are exchanged during fights (nothing major, e.g. I don't like you). I discourage those behaviors as best as I can.

DS9 is very sensitive about those comments from his sister (and others of him for that matter). Sometime, he gets so upset that he says he wants to kill himself. I try to tell him that we all love him regardless whether his sister does or not, tell his sister to apologize to DS, etc.

Before brushing it off as an attention seeking behavior, I want to see if anyone else has encountered this before.

TIA
