Jenny thank you so much!
It's interesting, I remember reading another thread on here, months ago, but made essentially the same point as yours, that the tiniest chink of light can stimulate wakefulness. I just nipped into Stan's room now to put away some laundry, he has a nightlight on now which I am
trying to show the difference between time to wake and time to sleep (it has a bunny which wakes up at a given time). I could turn it off. Honestly I am worried that without any light at all he will be frightened because he won't be able to find his way to the door when he wakes up. His room is very dark (it's at the back of the house and of course blackout linings on the curtains), it really is pitch dark in there when he wakes at 5.30. I don't know, maybe I should try it tonight?
We've been doing a 5.5hr last A time recently which worked for a time but last night he was back to 9.5hrs sleep
Hmm I don't know what to do now! I guess the worst that can happen is that he will cry at 5.30 am and I will go in.
