This seems to be such a universal problem, the majority of parents struggle with it! We had our little guy in bed with us a lot of the first year, primarily because it was easier for me to nurse that way - hee hee... We had to walk ours to sleep for bedtime and naps (he'd go back out after nursing during the night so that wasn't an issue at the time) and here's what we did at about 9 months: We were not interested in the 'cry it out' method at that age, we knew he wouldn't understand why we were ignoring him and he'd feel abandoned. So we sat on either side of the Pack'n'play he was going to be sleeping in and laid him down and he cried his head off. We sang and rubbed his back, head, legs, etc. We'd give him fifteen minutes, then one of us would pick him up for five, to let him calm down, then we'd put him back down again. That first night it took three pick-ups, then he fell asleep during the fourth lay-down (so about an hour). Same thing the next night, but on the third night it dropped down to three. A couple nights of that and it was down to two, with periods of calm during the 15 minute 'down' sections. Overall it took about two weeks to get down under 15 minutes of distress, then by the end of three weeks it had become a new habit and there was no crying at all. We really felt good about our compromise, yes he cried, but he wasn't crying alone. We like to think that while he was really mad we weren't doing what he wanted, he knew we were there for him and still loved him. It was hard, we certainly didn't look forward to bedtime for that first week, but as the situation steadily improved it got easier, and those three weeks seems like nothing compared to the hours of walking him over the previous months! I read the 'no cry sleep solution' and was profoundly affected by the description of what a crying baby left alone in the dark goes through. We figured there'd be some crying in his life, but our goal was not to abandon him to do it alone and it's worked so far!
