I let my first son cry it out, by going in every 10 minutes to rub his back, but NEVER pick him up. By the 8th night he didn't even make a peep when I set him down, just grabbed his penguin, smiled and laid down. He was 9 months old at the time. We did move 3 months later and have to go through it again, but we waited a week for him to get used to the new place, and then he only cried for 2 nights.
My second baby cried for over a half hour and I just couldn't take it, so I nurse him 'til he's sleepy (he usually pulls off and wiggles around, so I now he's full), then set him in his crib and sat in the rocking chair. He would get up and fuss or try to shake his crib. I just ignore it and tell him "It's bedtime buddy. Lay down." It took about a week before he would stay laying down and a week after that I set him down and walked out and he didn't make a sound. It took longer, but we still achieved our goal.
