AuDHD twins age 8 with a PDA profile - one of them is still not asleep and it's bloody 10.50pm. We can't leave them to go to sleep on their own because they just won't fall asleep and one of them gets distressed due to trauma if they think they have been left alone (school trauma), which means me and dh basically get no time together. No family support whatsoever. Also they're home educated because school forced them out due to unmet needs.
How can i get them to go to sleep? I know about good sleep hygiene - it doesn't make a difference. if we can get them into bed earlier, they still don't fall asleep any earlier. Please help.
