Lilli-Pilli's mother is having a baby. Lilli-Pilli is sure the baby is going to be a sister. She can feel it in her wings. But when she asks around among the birds and butterflies in the forest, some of them are equally sure the new baby will be a brother - and they can feel it in their wings, too! Lilli-Pilli knows she will love the new baby whether it's a girl or a boy, and takes lots of care to find ways to make the tree-bark cradle more comfortable, but she can't help wondering ...which will it be? She doesn't have to wait long to find out!
