I was just told my 3 year old who I have custody of and has been diagnosed with ptsd, rad, autism, severe anxiety and adhd will have a similar situation. I was told his new teacher is not as nurturing as his previous ones. She strict and she leaves no wiggle room. I too am concerned about how this will work as last year I had a parent advocate for him that if it was a bad morning I gave her a quick heads up she would meet him straight off the bus and help him transition. I too have to wait an see, but I will not tolerate him being triggered by her and then a meltdown! And his are very violent. It it his first full year!
