Has anyone had any success with wake to sleep? My son is 2.5 and has always been sleep trained. However have had issues with sleep lately. Have just successfully dealt with night wakings but now dealing with 4:30 wake up time. It's too early for him. By 7am he's visibly tired. He goes to bed around 8pm and usually woke around 6am. He has never slept past 7. And 6am is a good time for him to get up. He naps for roughly an hour to 1.5. Just wondering if he is too old for wake to sleep? Thoughts?
