A new baby is coming and everyone is so excited! Everyone except Ella. Her parents ask her and older brother, one question for many months: What should we name the baby? Ella doesn't even want a new baby; she's already the baby! So she suggests names like Squirt or Lumpy. Ella will need to learn about growing up, coping with changes, and her own family members before she can be the best big sister to a new baby--a baby who probably won't be named Lumpy!
