My son is also an early bird and lack of sleep affects his moods. He also has trouble falling asleep. I found that having the room at a cool temperature helps him fall asleep. There are times I have to leave the light on for him to fall asleep and that works. Having a fan on just for noise helps. I usually cover him with a heavy blanket just before I go to bed as it will help in case he gets cold in the morning or even the feel of something heavy on will help him sleep in a little. Maybe an extra 30mins or so. If he is up before me, I have him watch a t.v show or use his kindle as long as he can stay quiet for another hour or so.
