Chan began writing the novel in 2014. Chan was inspired to write about motherhood and parenting due to her anxiety over whether or not to have a child. Two articles published in
The New Yorker, one by
Rachel Aviv concerning a mother's experience with family courts, and a second by
Margaret Talbot about an effort in
Providence to close the "
word gap", both informed Chan as she wrote the story. The novel includes a large cast of characters, and Chan found creating unique, full-fledged personalities for the mothers at the titular facility "quite challenging". Chan set portions of the novel in Philadelphia, where she lived before moving to
Chicago during the
COVID-19 pandemic. Chan and her agent, Kaffel Simonoff, revised the novel together before submitting it to publishers. ==Critical reception==
