Hi S.,
Best book I've ever read for parenting: "Healthy Sleep Habits, Happy Child" by Dr. Marc Weissbluth. Check it out from the library if you don't want to buy it--I think you can often find it in the infant section at Walgreens? Helped me through all stages with my kids and continues to as they get older. Almost everyone I know who has read and truly tried these techniques has great luck.
At that age he's old enough to sleep thru the night and cry it out--and I've found that being consistent with this helps with discipline later on in other areas too. He shouldn't really need anything to eat during the night at that age, but I know how hard it can be to break a habit...been there! Good luck:-)Read the book, it's worth your time!
