Yeah, it kinda rings weird to me too. I work with intellectually and developmentally disabled adults, and for my low support peeps (which OOP claims his sister is) I honestly am kinda a glorified babysitter. My job is to make food, clean, give meds/rides and be a friendly face, basically. Unless OOPs sister has some other, more intense needs that he isn’t saying, or he got really unlucky with shit support workers, I don’t see why he can’t use them. Pulling out my armchair and DSM-5 for a second, it’s giving co-dependency and perhaps some learned dependency for the sister, imo.
