A humorous book about what every older sibling needs to know, filled with information about the new baby at your house, from mom of three and the #1 New York Times bestselling author of She Persisted Chelsea Clinton. Is there a new baby coming to your home? One that will sleep and cry and demand attention and…poop? Well, welcome to the Big Kids Club! This book will teach you what every big kid needs to know about their baby: what your baby can see, why your baby cries, when your baby will be able to talk, how your baby knows you love them, and so much more (including why your baby poops so much!). With artwork sure to cause big-kid-sized giggles, this book is perfect for any member or soon-to-be member of the Big Kids Club.
