This book is exactly what one expects from the title. Harper becomes a big sister to her new little brother Wyatt. Her and her dads are very excited for this new adventure. Things are harder than Harper expected. Wyatt is not able to play and both dad and daddy are not always available to do what Harper wants to do. Things are changing and it’s stressful. But as a family, they can get through things together. This book is well done, the illustrations are nice, it has a lesson and it teaches it well. Overall, this is a great book for any collection.
