The Wonder Weeks (Used Paperback) - Hetty van de Rijt, PhD, Frans X. Plooij, PhD, and Xaviera Plas-Plooij

The Wonder Weeks answers the question, "Why is my baby cranky, clingy, and crying?" with helpful guidance. Maybe they're experiencing a leap in brain development, after which new skills are mastered, discoveries are made, and perceptions evolve. Fussy behavior might signal that great progress is underway! 

Better yet, these phases occur on similar schedules for most babies- as explained and mapped out in this book- so you can anticipate the "stormy weeks" that precede the "sunny weeks."
