DD has ADHD and is waiting to get tested for autism. Today in a melt down she picked up a knife and said she was going to stab herself. Took it off her and tried talking to her but she didn't want to know. I've just done a recently watched on YouTube and there's this animated cartoon and the girl "stabs" herself (you don't see it happening). DD must've watched this. So my question is do you think it's just something she's copying or should I call someone about it? She's seeing the peditracion next week should I wait untill then?
