HarperCollins Children’s Books.

Ash and Daniel are no strangers to feeling like outcasts. As someone who cycles through genders, it’s a struggle for Ash to feel in control of how people perceive them. Daniel’s been told he’s overly sensitive more times than he can count. As he and Ash join forces to save a rescue dog, things go from cute to complicated when they start catching feelings for each other—and Daniel thinks Ash is a girl. With so much on the line, they’ll have to decide to go against binaries and embrace the beauty of living in between or forever feel at war with themselves.

Gender as a binary is purely a social construct. This is a concept that is difficult for some to really wrap their minds around, let alone explain to their young children. Particularly for cisgender parents, knowing where to start the conversation on gender fluidity is the first hurdle. Here are eight books about gender fluidity to get the ball rolling.

Grayson is in 6th grade and harboring a secret: She’s a girl on the inside, even if her body doesn’t show it. Gracefully Grayson tenderly navigates the fears of coming out as transgender and how compassionate people like teachers can be so instrumental in helping a child find their true selves.

Lily and Dunkin by Donna Gephart

The Moon Within by Aida Salazar

Rivera has a friend coming to terms with gender fluidity, however, which can provide great insights on how to be a friend and ally to other genderfluid children.

The Pants Project by Cat Clarke

Liv is a transgender boy living in the closet. If that isn’t hard enough, Liv’s school invokes a new dress code forcing girls to wear skirts.
