Too Early Wake Up (4 1/2)

I don't know what to do anymore. I've tried earlier and later bed times. The end result is always 6a or so. Earlier bed time can some times result in earlier than 6a wake ups. He basically wakes up because of something and just won't go back to sleep. Because he wants to play instead of sleep. What can I do to change this? via /r/Parenting https://ift.tt/2GzOLs9
