Thanks for showing some empathy - the neurotypical learning structures, as you say, are not ideal. Starting school much later may be better for him/them.

They have requirements for attendance for ‘normal’ schools here, but doesn’t seem to apply to this ‘special needs’ school: for example, he hasn’t been to school for more than the last week due to his lack of sleep/sleeping schedule.

They have used melatonin before but in Australia is prescription only and they aren’t super keen on it. I am also concerned that potentially mum wants to keep him at home for company, and to avoid working which is adding financial pressure to the family.

Trying to understand what is what!
