This is where pandering to people's every whim gets you. People can't do their jobs, but no-one pulls them up on it because they'd go to pieces and either go off sick for 9 months because any criticism, any input at all that runs counter to their own version of reality gives them panic attacks, or they'd accuse you of something-phobia and have you driven out of your own job.
Yep. Someone on the other thread said that starting reception as a 4 year old is pretty stressful, but most of them manage it without 3 support beings. Imagine if we gave in to this, if every 4 year old insisted on bringing their Mum and their pet, it would fast become impossible to run the class. Someone having 3 support beings isn't without consequences for others and the consequence for the trial was disruption and distraction from the points at hand.
KM didn't seem to need any support when they were denouncing Allison and trying to cause her harm (unless the dog wrote the email?). Professionals should be accountable for their actions.
