Jacob learns that adults can be scared, too, when his new sibling is born prematurely. While Jacob has his grandma and his faithful teddy bear, Bob, with him at home while his parents are at the hospital, he still feels alone. The book portrays the range of emotions older siblings often have about a new baby, including fear, anger, and resentment, along with the added challenges of the preemie's health concerns and parents' frequent absences.
