That's good news Sazale, hopefully you will get some answers.
One thing I have learnt is that school/LA/SS don't like being complaints being made about them. They tell lies, to cover themselves.
I had a 9 year old, who was self harming and having suicidal thoughts due to anxiety about school. Despite SW referring him to A&E for an emergency mental health assessment after visiting him in school (weeks after LA forced me to return him to school) within 8 days, despite ds being subject to CAMHS A&E safety plan and GP signing him off from school. The same SW was trying to force me to return him to school again with threats of CP if I didnt, where he was receiving no support at all.
This was a 'CIN', a CIN desperately of some support in school, however SW didn't ask for support in school, instead she turned up at my house and told ds he was a 'law breaker' and that she would be back the next day and would be forcing him to leave the house and go to school.
I was a parent, who was up all night with ds, he was an emotional wreck, threatening to jump out of windows, threatening to stab himself in the head, head butting walls, cutting himself with scissors, hitting himself in the face with hairbrushes, scratching his skin off and covered from head to toe in scratch marks.
Ds was most def a CIN, a CIN of some support, not threats and being forced to return to the place responsible for his anxiety. I was a parent in need of some support, some sleep, a break of even 5 minutes, not threats.
Im not saying this will ever be the case for you, but CIN and the powers entrusted to the people can be very dangerous, when they get it wrong.
