How much nursing care does she need? If it's not that intensive and family could do alot then she could maybe stay at yours or a family members house, and arrange for a nurse or care worker (depending on whether the NHS or Social Services are the Keyworkers). Who will be on duty for your area during her stay, to come and assist or manage hygiene needs or other needs that cannot be met by the family. This would usually be a 1hour visit . If she needs more care then ask the home she is currently in about any respite services they know of, and there's bound to be a similar service in your area.
