I chose to teach DS in a gentle way to self-settle (patting, stroking his forehead, shhh-ing). I would leave the room to allow him to grizzle, but return if he cried. I did try CC on a couple of occassions (when I listened to advice from "experts" and doubted myself ), but it didn't work for DS - he got so upset that there was NO WAY he was going to sleep. I started the self-settling thing when he was 3 weeks old, but he didn't really get it consistently until he was about 3 months. Now he self-settles beautifully - I just wrap him, put him in his cot with some music & walk away. It's only in the evenings (when he's really tired), that I still need to give him some help to settle.
