My son is 12 weeks old. He has been sleeping anywhere from 5-6.5 hours at night. No matter when I put him to bed he wakes up between 3:00 and 4:00 AM. He gets tired for the night usually between 7:00-8:00 PM. If I put him down at that time he will often sleep straight to 3:00 or 4:00. I have been putting him to bed slightly later, waking him at 9:00-9:30 to feed him in the hopes he will sleep closer to 5:00-6:00 AM and it doesn't work!!
Any advice on how to shift this slightly?? I'm out of ideas!
