A young boy named Trott anticipates the arrival of a baby sister, imagining how she should be and asking his parents and God for her. While staying with a kindly blind neighbor, he wonders about where children come from, mixes fanciful notions with practical concerns, and watches adults with a child's curiosity. The narrative follows everyday household routines, family conversations, and small adventures that expose childhood jealousy, affectionate longing, and the gentle domestic rhythms that surround a family preparing for a new child.
