Ok. DS never liked going to school. It was always difficult to get him there, we were often late because it was get him there miserable but walking and be late or carry him there crying and screaming and being on time. It was tough.
Post lockdowns this deteriorated rapidly. The switch from infants to juniors probably didn't help, with the change to much more formal sitting at desks education, but DS was increasingly struggling with the social side. His meltdowns increased in frequency and violence, until he was having multiple violent meltdowns a day, I was covered in bruises, neighbours had called the police out.
He started refusing to go. We physically forced him out of the house and dragged him in. I regret this hugely now. His time in school was cut down, and honestly it was heartbreaking seeing him cower and hide behind me if we saw any children from his school, his time going in had to be arranged so he wouldn't have to see anyone. He could barely leave the house at all
Ended up moving schools to one with a unit for children with additional needs, where we worked very hard to get him up to full time, which he successfully achieved. Also got a diagnosis of ASD.
Then secondary school. First year went ok, then he crashed and burned, would go in initially but stopped going to lessons and just talked to a favourite member of staff about wanting to harm himself all day. GP/CAMHS were bloody useless, so paying privately for counselling. He now attends school for an hour a day, no lessons yet.
I honestly don't know what what we could have done - his teachers themselves have commented on how much effort we've put in, how engaged we are. But I won't make home an unsafe place for him, especially as I don't think it would make him magically able to attend school, reward/punishment like that has never worked for DS around school, it just causes more distress and makes him less able to attend.
