Hi Bethiew, I join LP in welcoming you! God bless your family 7 children!
I think it is easy for hospital staff to have the view of "bring her home and try again". We all know this is easier said than done. My D17 had been hospitalized many times before placement into residential and she was begging me to bring her home to wait for opening. As hard as it was for her father and me, we couldn't allow it as we were not confident we could keep her safe.
My D remained in the hospital for 2 months for her placement to be made. I would be very cautious as we know how manipulative our kids can be
times. If you don't feel you have he strength/ability/sanity to keep her safe
home then I would fight for the hospital to keep her until appropriate mental health arrangements can be made, not a shelter.
Stay strong and keep us updated.
