Have you thought about investing in a co-sleeper bassenet? They are adjustable hieght and are open on one side so you can be close to baby without him being in bed with you. My second child wouldn't sleep in hers either but that was eight yrs ago and the co-sleeper was not out yet. I knew from experience I could not get her use to sleeping in bed with me or it would never end. I was able to get her to sleep in one of those viberating baby seats which I placed on the floor near my bed. If she was fussy I was a reach away to touch her or gently bounce her. It is a more affordable option if you cannot afford to invest in a co-sleeper.
