Peepy is the son of Mrs. Jellyby and Mr. Jellyby and the younger brother of Caddy Jellyby. Esther Summerson meets and takes pity on Peepy when she first arrives at Mrs. Jellyby’s house and discovers that Peepy is neglected and that nobody notices when he falls down the stairs and hurts himself. Peepy grows attached to Esther throughout her visit because she is the first person, other than Caddy, to be motherly towards him. Peepy eventually becomes the servant of Mr. Turveydrop.
