Ds ASD (6) just gone into YR2.
He has always struggled with his behaviour, his fuse is very short and is lit by the smallest of things at times. He is very demand avoidant and we use various methods at home to avoid placing too many demands. However he had a good latter half of YR1.
Behaviour issues are now on the increase at home since going into YR2 and whilst I expected this to a degree for all the obvious reasons, I went to see CT who confirmed there were daily issues and that there was a new boy in the class who ds has taken a dislike too (very unusual for ds). I explained that these issues need to be reported in the home/school diary or how else can we address and CT confirmed this would happen going forward. Still wasn't too concerned as it's still early days and his new CT needs to adjust to me too 
Yesterday his NT twin brother reported seeing ds in another classroom... no mention in home/school diary so I asked CT to explain.
Apparently yesterday his CT went through the visual prompts and expectations with him and basically he gets 3 requests to alter behaviour... followed by a timed visit to a YR1 classroom. It has also been reported that today during an activity ds pointed a pair of scissors at CT and "held a stare" when getting frustrated, then did a similar motion with a stick at the TA. I'm very concerned and admit I'm struggling to understand where this type of behaviour is coming from.
I'm torn... clearly we ALL have to address the behaviour issues but this is what they do with all the children and to my mind they should be putting more effort into understanding why these behaviours are happening although I appreciate that negative behaviour needs to be followed by a sanction.
Any ideas...
