You've not had any explanation from anyone? You said her sister lied to the police, why were they involved? It sounds like there's more to the story. But if it were me in that situation I would do literally anything to get onto that ward and see my wife. I think this situation is probably outside the scope of this forum, you should go somewhere where you can get legal advice.

Her sister called the police claiming that I had told my wife I would take her off the ward during the only time I have been allowed to visit. This was simply not true. She was heavily under the influence of morphine and begged me to take her home. She also asked for razor blades.

They also called social services and the police claiming that I was not taking care of my son properly.

My wife has been ill for a long time as I said, and when admitted to hospital her sisters were first to visit in the hospital as I was traveling home. They set a password on the care updates, and since then I have not been able to get any updates. The police advised that I could be charged with harassment.

I feel she is being coerced to be honest, and I am seeking legal advice.

I do not feel taking an 8 year old into such an environment would be good, it feels like I am damned if I do or damned if I don't further down the line.
