Query: A flexible, child-centered approach to sleep

It's true; the NCSS is NOT an overnight solution. But it will work, and parents will feel good about how they achieved results with their children.NCSS has one advantage over all other sleep books: it is flexible. Most sleep books have a dogmatic program parents must follow (because if it didn't work, you didn't do it right, say the others), but Pantley lays out possible sleep issues and provides parents a menu of possible solution. Parents then learn with their babies how to create the bet night's sleep for everyone.Best of all, the book is written in an encouraging tone. Parenting is hard, and Pantley knows that parents need to be treated as gently as their babies.
