Hello. I've suddenly thought that maybe DS wakes up so early as he's hungry. Goes to bed no issue, sleeps through but up at 5, 6 if I'm lucky. He doesn't mention he's hungry, but I just read a comment on another thread and thought maybe he needs an"supper" to keep him full till morning, we have tea at 4:30 so finish eating about 5 (slow eaters in this house!)
