Just an update, in case anyone is following the thread.
I decided to put up some blackout material on the window (we had it up last year but it irritated my husband so I took it down in the winter). I did that 4-5 days ago and since then, he’s slept until at least 6.30 every day, sometimes close to 7! It might be a coincidence, bc I have been following Creations’ advice about timings too, but i think it has helped. He already has blackout blinds but they aren’t well fitted bc they let lots of light in around the edges of them and his bedroom faces east so he gets all the morning sun
Anyway, all is well again, until the next leap or tooth! 😊
