i haven't read any of the responses, and this probably isn't the answer that you want to hear, but he is only 9 weeks old, try to go with the flow and relax, i was like you, in fact i sounded just like you, i went to sleep school THREE TIMES and wasted so much energy trying to get my baby to sleep how and when i wanted her to, the thing is, sometimes you are doing ALL THE RIGHT THINGS to promote great sleep, but guess what, they are just babies, and you no matter what everyone tells you and what all the books say, you can't control them, you can only create a sleep conducive environment and hope for the best.... looking back if i were to have my time over, i wouldn't have worried about sleep habits until probably around 6 months.... they are only small for such a tiny blip of time, even though it feels like eternity at the time when you aren't getting much sleep, i just think i expected too much of her too soon, and forgot to just relish all the newborn things that so quickly fade.... best of luck, enjoy your baby, before you know it he'll be running around xx

sounds like you are doing a great job and you have a healthy happy lil guy, just keep creating a great sleep environment, and one day he will catch on, i promise.....
