Oh yes, I third taking baby's lead. I monitored Little Miss' habits for the first couple of months, and the only thing we did regularly was dim the lights at night, and then give her a bath before putting her pajamas on. She was 3 or 4 months old before I started to try to "put her to bed" (in her co-sleeper, we co-slept and bed-shared and still do), and as the previous posters mentioned, we always kept bedtime super-positive.
Actually, Mr. teased me that my methods would surely backfire, as if Little Miss could not get to sleep after a certain amount of time, I'd just take her out of the bedroom, feed her my nighttime snack and snuggle her while we watched TV. So basically, her reward for not sleeping was snack and TV. But at 14 months she's been reliably self-settling at her bedtime for several weeks now. I just kept doing her routine (bath, jammies, story, nunnie, bedtime) and not forcing the issue. It's misery when they won't sleep, but that doesn't last forever.
