Keeping the trademark month-by-month format that allows parents to take the potentially overwhelming first year one step at a time, First Year is easier-to-read, faster to flip through, and new-family-friendlier than ever—packed with even more practical tips, realistic advice, and relatable, accessible information than before. Illustrations are new, too.

Among the changes: Baby care fundamentals—crib and sleep safety, feeding, vitamin supplements—are revised to reflect the most recent guidelines. Breastfeeding gets more coverage, too, from getting started to keeping it going. Hot-button topics and trends are tackled: attachment parenting, sleep training, early potty learning (elimination communication), baby-led weaning, and green parenting (from cloth diapers to non-toxic furniture).
