When will he grow out of this?

My DS goes to bed between 7pm and 8pm and wakes up within 45 minutes of going to sleep.  Sometimes I can get him to go back to sleep (but he usually wakes up again quickly) but usually he is up until after 10pm.  I feel like I've tried everything so I'm just guessing this is something he will grow out of eventually.  Has anyone else experienced this and then experienced it going away?!
