Name changed as very specific event that could be identifiable.
My first born started school today, he turned four 6 weeks ago. We have had some behavioural challenges the past year, somewhat exacerbated the arrival of his little brother. But we have made a lot of progress and only had two aggressive incidents this year. He has attended both a preschool setting and childminder setting. He has never been aggressive at the childminders but he did bite his key worker at the end of last year but no issues there since then. Childminder suspects ADHD due to his nature, either hyper-focused on something or very energetic and loud. He also gets overwhelmed, less so recently, but when he does he turns into a dinosaur or animal, his two obsessions.
Anyway, was his first day at school today and we arrive to collect him, all the other children are stood in a gated area waiting to be collected one by one but my child is nowhere to be seen, eventually, teacher comes to us and says to find her at the end and we are led into the classroom where my son is. He has hit one teacher, and bitten another. They said it was when he was told off for 'roaring' at other children, so he had gone into overwhelm mode. I was very blindsided at the time as wasn't expecting to have these aggressive challenges but prompted somewhat in June that he may struggle with being overwhelmed by speaking to the school lead senco, also spoke to his teacher about all of this last week at a home visit and the childminder and preschool also had conversations and visits with his teacher where some of this behaviour was highlighted, albeit not as aggressive as this. but they acted like these conversations hadn't taken place.
I know this thread is a mess, I'm tired but I just wanted to know if I am alone in this, do many children struggle this much on their first day? Is this indicative of a bigger problem? Really unsure on how to tackle this as we have been doing lots at home where his behaviour has improved massively but feels like today at school he has regressed back about a year. I feel like I have failed him.
