One major dynamic of advantage and disadvantage that especially affects early childhood practice is that of the ‘visibility’ or ‘invisibility’ of certain kinds of people
or cultures in a program. Too many early childhood materials focus on children and families who resemble the stereotypes of American culture as it is most commonly depicted—middle-class, White, suburban, able-bodied, English-speaking, mother-and- father (nuclear) family—as if these were the only types of children and families we work with.”
