Work through the case study of Susan (150-250 words). Susan is a 26-year-old mother who has two children. Susan's youngest child (4) lives with her father due to a custody arrangement. Susan's oldest child (Betty, 6), lives with her in a basement apartment. Susan binge drinks and sometimes it lasts up to 5 days. In these moments, Betty does not go to school and she makes her own snacks when she gets hungry. At times when Susan gets sick and throws up, Betty cleans up her mother and any messes she sees around the home. One morning, a Children's Aid worker knocked on the door. Betty opened the door and let the worker in. The worker informed Betty and Susan that Betty was now going to live with her sister and her sister's father. Betty was visibly upset and stated, "But I can't go! Who will take care of mommy!?" What are the physical safety concerns in this case study? What are the emotional safety concerns in this case study?
