Sorry. A little while and you can offer to take her for a hit and see where things go from there
Is your goal to have your sister come and live with you? Would your mom allow you to let her do that without getting anyone involved by maybe suggesting that she needs a break for a l
If you think your mom is abusive towards your sister call cps and tell them about it, get some feedback on what you can do , they may send a social worker round to check. Your mom indeed may have trouble coping if she is depressed she does need some help I dont know how you can make her get help if she wont go .What about the 2 friends she and your sister live with do they treat the child well ?
My sister does with my mother, and her two friends. But one of them feels as though my mother may hurt her. Psychiatrists say she is dealing with depression, but they say that she only thinks it. She refuses to see any kind of psychiatrist who doesn't agree with her. She will only tell them what we "do to her" which we do nothing at all. And in reality its her doing everything to everyone else.
Your 6 year old sister drinks coffee, may I ask who the child is living with as you say your mother does come round ?The people to contact would be CPS child protection services, they would give you information where you stand if you told them what you have written here. .I agree this is not good behavior but possibly your mom could get some help if she is dealing with depression or anything may make her behave this way .
