What is the narrator point of view in the novel, How Beautiful We Were?

The novel is set in first-person, switching with each chapter (as well as occasionally within chapters) between first-person singular and first-person plural. The change in point of view is announced by the chapter titles, with odd-numbered chapters all being titled “The Children,” and even-numbered chapters titled with the name of the narrator, who is in each case a member of the Nangi family (in order, Thula, Bongo, Sahel, Yaya, and Juba).
