I am so sorry to hear about what is happening. This is a frightening and confusing time, and hospital staff should be working with you to alkeviate the stress of the situation. My advice to you would be to make a written complaint to the hospital. Sometimes patient care is second place to rules and regulations. Write, with the facts, to hospital complaints. You should find an email you can send the complaint to. The complaints team should deal with it and give you peace if mind.
I'm giving you this advice because I had to make a complaint when I found out the hospital were going to discharge my dad, they hadn't informed me, it was winter, and he had no coat and no door keys. The complaint was dealt with efficiently and without stress and most importantly the relationship between the nursing staff and us was preserved.
Good luck. X
