When the narrator of this story discovers she's going to have a new little brother, she's not so sure she wants one. Neither is Bubbit, her very special blue wool bunny. Her grandmother, Nonni, made Bubbit for her when she was born, so they're practically like twins. Soon it's time for the baby to be born. Nonni comes to stay, and she brings her sewing box. And before long, the narrator has decided to sew her new baby brother something almost as special as Bubbit.
