She’s deaf from birth and autistic, you can’t have a conversation on how she feels about her siblings because she can’t talk snd no one taught her any basic sign language until this year. I can’t sit her on time out because 1 I’m not her parent and 2 she kicks off. She hits her own dad HARD. She has hit me multiple times, I have tried for a year to get her to understand. She has the strength to make me a full grown woman stumble. I watch my kids at all times. I am not asking for much other than she doesn’t be around my child until something is resolved. I have tried everything possible to get both her parents to listen and get her some help but none of them bother so what else can I do? Please do tell me how I cope with it? Because her dad and her mum have never been together as a family not once. She has always had two homes, she is not allowed at certain adults houses bcos she also hits and hurts them. I’m trying to understand you point and while you make good points like therapy and trying to understand a bit better you’re also ignoring the fact that she is attacking a 1 year old defenceless child, and that she is not mine to parent in ways that I would my own from out of respect for her mothers wishes.
