Try to investigate to see if something is happening around that time that is pulling him awake. Someone next door has started going to work earlier and he is hearing their car???
Something in the house or neighborhood may have changed. Sugar right before bedtime can cause an alertness but that would usually happen more like 12 or 1. When his body finished processing the sugar it will wake him up. But the timing if off for that one.
I can help you get to sleep earlier though. I am the person who never sleeps, Just was not sleep and could not do it. I can read all night long. And have been that way my entire life. But I recently discovered that if I put on a headset (I like the ones that fit behind your head not over) to my CD player and A "books on tape" turn it down very low so I can just barely hear it. I go to sleep immediately. Sometime during the first sentence but usually before the first CD is finished. When I take them back to the library I can check them out again, because I've never heard them all the way through. I keep an old Harry Potter one that I've listened to 14 times and It puts me to sleep because now it is boring. See if that helps. Go to beD earlier and SLEEP. AHHH.
