Hi,
I've just had to take my son out of school because he was having panic attacks, and I am seeing how he changes now he is out of the school system.
The thing I'm really noticing is that he is desperate for outside exercise. At first it was all books, books, books, but now he is desperate to get out in the sunshine and walk around. Our best days are now those where we do physics or maths in the park, or biology or geography looking at an actual pond.
DS has developed an aversion to screen-based teaching because of all the nastiness he has seen on screens in school. He can't bear powerpoint teaching or youtube learning because he never knows what he will be exposed to next and was having paralysing panic attacks.
FWIW DS does definitely does have differences (SEN), because he needed surgery twice as an infant to keep him breathing, and that was caused by wheat intolerance, so that is definitely an environmental factor.
However, he was always immaculately behaved in school, and got all As for attitude.
I am a stay-at-home parent and always have been, so he has had me around, but I have also had health problems that I couldn't get help for, so that has been limiting. I think the under-funding of the NHS is a big problem for parents who are then struggling to help their kids.
I don't think it's fair at all for teachers to blame bad parenting. It may be that in some cases, but it isn't in all.
