LO is now 12 weeks and seems no closer to sleeping through the night. He generally goes down about 9PM and then sleeps until 1 or 2AM. Eats for about an hour. Sleeps for another 2.5 hours. Eats for about an hour. Sleeps another 2.5 hours.

Not terrible, I realize. But is there anything I can do to encourage sleeping through the night? He's always hungry when he wakes, so I don't feel like I can try to cut feeds. Do I just have to wait until he gains more weight and can go longer without eating?
