Some scholars of
children's literature consider ''X: A Fabulous Child's Story'' to be part of the lineage of modern
children's books with transgender themes, even though the story does not explicitly deal with
transgender identity. While Fremont-Smith wrote in his 1978 review of the book that Chwast illustrated X wearing exclusively
overalls "to avoid the taint of transsexualism or campy drag", Jamie Campbell Naidoo wrote in 2012 that ''X: A Fabulous Child's Story'' may be a precursor to newer works which do feature explicitly transgender children, like
Marcus Ewert's
10,000 Dresses. Similarly, Julia L. Mickenberg and Philip Nel described ''X: A Fabulous Child's Story'' as the first picture book that was sympathetic to trans people while Robert Bittner, Jennifer Ingrey, and Christine Stamper wrote that it was the first picture book to include a non-gendered child as one of its characters. ''X: A Fabulous Child's Story'' was Gould's only story for children. The story has variously been anthologized as radical children's literature and as
feminist science fiction, and has also been collected in
social psychology and
gender studies readers. The story partially inspired an experiment by three
City University of New York researchers to test the effects of introducing an infant to adults without identifying its gender; their work was reported in the journal
Sex Roles in 1975. ''X: A Fabulous Child's Story'' has been reported to be difficult to find copies of in the 2010s. ==Adaptation==
