The character and history of each child may be a new and poetic experience to the parent, if he will let it.

Fuller suggests that parenthood can remain an imaginative, almost artistic encounter rather than a routine of management and control. Each child arrives with a distinct “character and history,” and the parent’s task is to stay receptive—to “let it” be new—rather than forcing the child into preconceived roles or expectations. The line reflects Fuller’s broader Transcendentalist emphasis on individual development and the moral value of attentive perception. It also implies that the parent’s own growth depends on humility and openness: the child is not merely shaped by the parent but can become a source of ongoing discovery, wonder, and ethical education for the adult.
