When I first saw this books, I thought it was a picture book, but it is somewhat like a chapter book without actual numbered chapters. A great book for early readers who want a bit more to their stories. The illustrations are not on every page, but there are enough to interest even the younger listener. Liam is in kindergarten when he finds out that his mom is going to have a baby. He waits and waits until it is time and she is born. He is home with Nana-Downstairs waiting for the big event. I love that she is not the typical grandmother depicted in children's books. She is feisty, fun, does yoga and has her own workshop where she builds stuff. When Liam realizes that Sophie is not going to grow up fast enough for him, he gets frustrated and angry. His family helps him to deal with it and to love Sophie just the way she is. I read this book with my four year old grandson and he liked it. He was able to relate to when his mother had his baby sister. This is a great story for children waiting for a younger sibling or if they have just had one. A perfect choice for a family library. The publisher generously provided me with a copy of this book via Netgalley. ( )
