I used Gordon method for DD1. We weren't cosleeping but we were night nursing so I found it a very useful technique.
With DD2 (15mos) I am currently nursing her at bedtime and then put her down in her crib awake and then I lie down on the floor in her room with my eyes closed until she's asleep. The first night she stood in the crib staring at me and screaming for about 15mins. The nights since then she does that for maybe 2mins at max then flops herself down and goes to sleep. I figure this way I show her I am there and not abandoning her but yet I'm not shushing or holding or rocking. Oh and I've reminded myself that her screaming cries are just her way of being mad at me. She isn't crying in a "I really need you mommy" way but in a "You b$tch! I can't believe you just put me down in the crib" way and I just keep telling myself that I won't let my 15mo bully me LOL!
All that said, I think commitment to a process, whatever that this (Gordon, CIO, etc) is really important. You have to find something you are comfortable with and really stick with it for as long as it takes...which could be a week or two. I figure that kids are like animals and can smell fear and weakness and will exploit it until you cave in LOL! So, if you aren't ready to do it and stick to it then keep on doing what you are doing. I also think it is important for your DH to be 100% on board with the plan too. Oh, and for me personally, cosleeping and weaning were not compatible. It was much easier for DH to put DD1 back to bed than for her to be lying next to her favorite boobs and be told shhhhhh go back to sleep.
