My Baby Sister Is a Preemie [EPUB ebook] 

It’s pretty scary to see a new sibling wrapped in a glass box instead of a soft blanket. In this gentle story about a baby who arrives too soon, Sarah can see that Mommy and Daddy are worried, and that tiny Amy is sick. But her parents help her to see that God is with the family no matter what, even its newest, littest member. A special section at the end written by R. Scott Stehouwer, Ph. D., professor of psychology at Calvin College and clinical psychologist, provides suggestions for parents and caregivers of hurting children.
