Honeymonster... I should say he doesnt sleep through the night without waking up.
He just doesnt eat anymore at night. Until recently he was a habitual waker at 3am, so I set my alarm for 2:15am, go to his bed and change his position in bed. So far, that part has worked though he has been waking up other times but can be settled back to sleep fairly easily.
He's on a 3.5 hr EAS now which seems to work a LOT better than the 3hr routine for him. Soon, I'll move to the 4hr

He's usually fast asleep at the 2.5hr mark. I start aiming for sleep 15min before. His total sleep during the day is about 3 hrs. Seems to give me an 1.5 nap in the morning and the next two are 45min- 1hr long. No catnap for him unless every nap was 45min than I shoot for a catnap.
I think that already a 4hr easy would be easy to implement because sometimes he sleeps longer and its 4hrs since his last feeding.
