Sleep training

Samantha

I feel like I've posted a lot about my little girls lack of sleep at night, and have always been against sleep training because I don't like to hear her cry at all but I need to try something.

I've heard a lot of good things about Taking Cara Babies but I do not have an extra almost $200 to spend on a video course.

Are there any other books or methods or tips, anything that has helped you?
