My son has just been on a physio course for a couple of weeks at a very well-known hospital.
It was like a boot camp.
The children were shouted at, told they were pathetic if they didn't get things right, ordered to do increased tasks as 'punishment', told to shut up etc.
I felt really uncomfortable about this. DS told me and I checked with other children who agreed this was going on.
I raised it. It wasn't denied but I was made to feel like a 'clucky' mother and pretty much 'frozen' out as a result and treated very abruptly (and quite rudely) on discharge.
Seriously, though, adults wouldn't accept this, why should vulnerable children?
