Whatever you do, I agree with other posts, consistency is the only way it will work. We never let our daughter in our bed (I was terrified of rolling over on her or smothering her with our many feather comforters) but had her in a co-sleeper until six months. When we moved her out of our room and into her crib at that time, we sleep trained. First we eliminated the midnight feed and kept the 4 am feed. Then when we had checked with our pediatrician that she no longer needed to feed at that time, we cold turkey stopped it. It took three days. Thirty minutes of crying the first night, twelve the next night and five minutes the third. It's heartbreaking but ultimately, she was sleeping better and longer almost immediately. She is now almost two and sleeps very well at night. We were so concerned with keeping her nighttime sleeping as long as possible that we neglected naps so had to sleep train on that front later than I had hoped. Again, at 18 months, it only took three days to transition her from napping in the car to napping in her crib. Long and short of it, decide of a course of action, stick to it and see what happens. Every child is different, so no one else's approach may be perfect for you, but once you decide on a course of action and give it two or three days, you may be amazed at what can happen. Best of luck. Sleep for all of you is around the corner.
