How to say stay away for me and my daughter

Clare-marie

Hey ladys, so I had my 4th baby 6 weeks ago and my young sister was pregnant (20weeks) anyway she aborted her baby due to her being on drugs (meth) but she is telling people shit. DCP told her to give it up or they will take baby when she was born. My sister is not asking me to see my daughter as she is lost I dont qant her near my kids due to her being a drug meth head. She has lost 2 girl to DCP. I want to tell her to stay away and I don't want to hear near my daughter and I don't want to hurt due to her losing her daughter and sound nasty. Please help....
