Sleep-deprived moms and dads take note: The two women who help Hollywood's A-listers get their ZZZs share their no-fail, family-friendly solution to get any baby, toddler, or preschooler to sleep—usually within less than five nights. Pioneers in children's behavioral sleep, Jen and Jill give parents the key ingredients for success: a customized sleep plan, step-by-step instructions, and plenty of emotional support as your child learns. In this fully revised edition, they share updated methods for their "least-cry" approach—refined over nearly three decades—to ensure that children learn good sleep skills quickly, with a minimum of tears. You'll learn to: gently shape sleep for newborns birth to twelve weeks old to create a solid foundation; teach your baby or child how to sleep through the night and take great naps; customize the level of support for your child's sleep learning that feels best to you; say goodbye to early morning wakings; end bedtime battles with verbal children; troubleshoot stumbling blocks like illness, teething, sleep regressions, and travel; and access updated sleep planners, visual aids, and highly detailed schedules.
