Originally developed for newborn multiples, this sleep-training method worked so well with twins and triplets that families with singletons and older babies began asking Suzy to share her recipe for success, resulting in: regular feeding times; 12 hours' sleep at night; three hours' sleep during the day; peace of mind for parent and baby; and less strain on parents - and their marriage. This edition includes a new chapter on implementing the program with babies up to 18 months.
