well it depends upon whether it is a locked unit or not, in my experience. On a locked unit, children visitors are allowed only with special permission. on a general (I forgot its name) unit, children visitors are allowed. I have been three times, in two different hospitals, one of them a teaching hospital (=residents). Groups - CBT, occupational therapy. On a locked unit, the computer and cell phone are charged in a special locked room and given to you during certain hours. And no shoelaces. On an unlocked unit, you charge your computer in your room, same with a cell phone.
