I hate to say this, but he's waking up because you are putting him to sleep... for a few days try to get him to be almost asleep and then put him down. I have used the cry it out method for both my kids. I don't know what you think about it. But if you are alright with it, then let him cry for a while after you put him down (when he's almost asleep) and see how he does. Gradually increase the intervals for which youlet him cry. With my son, it took me 3 days and he was sleepign through the night. With my daughter (who is 6 mosnths now) it took a lot longer. Don't give up - I almost did with my daughter, but now she sleeps like a charm on her own and when she is rocked to sleep. Think about it this way - you need the rest too, or else you can't give him the best care. Hang in there.
