Book excerpt: Everything you need to know about getting your baby or toddler to sleep -- from America's foremost baby and childcare experts. Babies don't automatically know how to sleep through the night; they need to be taught. The Sears family has learned from decades of pediatric practice, bolstered by their own parenting experiences, that different babies have different nighttime temperaments -- and, of course, different families have different lifestyles. Instead of espousing the kind of "one method fits all" approach advocated in other baby sleep guides, the Sears family explains how you can create a sleep plan that suits the needs of your entire family. With a sharp focus on the practical tools and techniques, The Baby Sleep Book covers such topics as: The facts of infant sleep vs. adult sleep Figuring out where, when, and how your child sleeps best Fail-safe methods for soothing a crying infant How to make night nursing easier, and how to stop Nighttime fathering tips Whether co-sleeping makes sense for you Nap-time strategies that work Medical and physical causes of night waking Sleep habits in special situations such as traveling, teething, and illness
