Our daughter, when pregnant with her second child, was concerned her son said he didn't want to become a big brother. This sparked a thought about bluebird brood behavior and this book was born. Originally written as a birthday gift for our grandson Leo, this book is a fable of sorts in the tradition of Aesop, in that true animal behavior is personified and a lesson is to be learned. Indigo blue bird is unhappy about the work involved in being the fledgling required to stay and help with a subsequent brood of bluebird babies. His mother although very busy in her preparation for the eggs to arrive, is concerned about him. She sends him to visit his wise Uncle Cobalt whom she claims was the "best big brother ever". Her feeling is that her brother could answer all of Indigo's questions and maybe work out his angst about his new role. The story unrolls the basis of love in families and presents Indigo with an aspiration to be a great big brother. The lesson to be learned is that Love grows beyond the boundaries of one heart in a family to encompass the whole family. "You just can't contain it." He vows to do his duty in love and after being a big brother to become a loving father to his own bluebird babies.
