should I mind my own or seek help. I know this woman who has 2 other kids. she is on strips to help with a heroin addiction. she is 17 weeks along and has yet to see a Dr for fear of loosing this one as well. her son is 7 months old, he has severe seziors and strokes daily. her daughter is 5 and nonverbal severe autistic. should I call someone. she is being neglectful. to me she is and never will be a mother.
