My Ds is 7 and disabled (possibly relevant as he can't get out of bed to come to us). Until 2/3 months ago he slept wonderfully, then started to worry about burglars when if got too hot and the windows were open. We soon closed them. Anyway he now sleeps until 2/3 am but wakes up and can't get back to sleep on his own.... I go to see him, and mostly he settles back down, but then wakes again every 60-90 minutes until I give up on trying to settle him at sometime between 6 and 7. I really really don't know what to do to get him back to sleeping through. We are all so tired, and I assumed he'd settle back down but now I am less sure. He seems to have forgotten how to sleep in his own and I am not sure what technique to try. We have tried calm, cross, patient persistence, bribery etc but not sure what will work with a 7 year old... Any ideas?
