My 15 month old won't sleep through the night...any ideas?

at 14 months we did the Ferbers method. We had similar issues our son wanted to eat all night... he could not put him self back to sleep. I would read about the Ferbers method... how you teach them to sleep on their own. Good sleeping habits is vital... with in 3 nights our son went from waking every 2 hours to sleeping through the night. It was incredible. Your son is old enough to learn. He has learned now that if he cries he gets nursed... nothing wrong with it... but if you were like hubby and I... we were tired and miserable... and our son was not getting enough sleep... and could be a handleful during the day... thanks to the ferbers method he sleeps well and eats better during the day etc...
