Elmore Green starts life as an only child, as many children do. He has a room to himself, where he can line up his precious things and nobody will move them one inch. But one day everything changes. When the new small person comes along, it seems that everybody might like it a bit more than they like Elmore Green. And when the small person knocks over Elmore's things and even licks his jelly-bean collection, Elmore's parents say that he can't be angry because the small person is only small. Elmore wants the small person to go back to wherever it came from. Then, one night, everything changes. . . . In her signature visual style, Lauren Child gets to the heart of a child's evolving emotions about becoming a big brother or sister.
