I have two CAh boys and both sleep great. It took work though, I did let them cry it out when they were little and now they never get up. They both sleep 12-13 hours and they love to sleep. I followed the "Babywise" sleep method, it is kind of hardcore, but it does give you the confidence to know that is is OK for them to cry. My little one was much harder to deal with sleeping, I would set the buzzer and go outside so I would not have to hear him cry. I know some people can’t do the cry out thing but if you can stick it out it sure does solve the problem in a hurry. Also both my kids are really happy during the day, I think it is because they are both really well rested.
