I totally understand what you are saying when you say "he is still using me to fall asleep",in other words, he is still relying on your comfort to fall asleep.
I would suggest trying a mixture of the ferber method and sears method, atleast that's what worked with my now 3 year and I just started this past Monday with my 9 month old. I start with staying in there until almost asleep then I go out into the hall and wait ( cuz I know she will cry), I wait about 3 min then go back in help her settle, lay her back down (if she is standing up), stroke her face and then leave. It takes about 15-20 min and she falls asleep. In one week she has cut down from 15 min to 5 min. The key to any sleep training technique is to stay consistant. I know it will be hard in the middle of the night but once he learns how to let himself fall asleep I think things will fall into place. Good Luck Mommy!
Also, I have learned that knowing your child and his needs will be your best guide. Books are helpful but they are only outlines to help you, try not to stress too much!
