How do you teach a child to self soothe..

[superfun]

I had one that started mid august and his mom warned me that he would take a while to start napping well. I guess he does that to her too. Any time they change his schedule or go to families homes, he screams instead of naps. So right from the start, we did CIO, and if he woke up in the middle I left him until the end of nap time. It was actually all her idea, even though that's what i would have done anyways. He is so loud! After about a week, the other kids were able to ignore him when they slept (all in their own rooms with fans or white noise). It was a rough week when all the other kids were not sleeping well. Anyways, it took just over 3 weeks, and now he sleeps well most days.
