How does the author use foreshadowing in Peter Pan?

When the dramatic technique of foreshadowing is used in Barrie's play, it is most often in conjunction with mothers and mothering; maternal insights usually telegraph important events in the play. Mrs. Darling had previously seen Peter in the window when tucking her children into bed and reading them stories. She is reluctant to go out to dinner with her husband in Act I because of what she has seen. Her worst fears are realized when Peter does come back for his shadow and convinces the children to come to Never Land. When Wendy assumes the role of mother to the Lost Boys and her own little brothers, she, too, develops a mature instinct. While telling her "children" a story about her home, she realizes, with the help of John, that her mother probably misses her and that they must return home.
