It’s time to color outside the lines of society’s gender norms, thanks to a brand new French-language coloring book.

‘Ça déborde !’ (It’s overflowing!) is designed for kids aged four and up, to help them understand that not everyone fits into neatly defined gender binaries.

With the help of thirty fun-filled educational illustrations, illustrator Sophie Labelle is teaching kids that it’s okay not to match society’s expectations.

‘Sandro/a is neither a boy nor a girl,’ the first page explains, illustrated with a picture of a child on a skateboard.

‘Xe identifies as gender fluid. Some days xe feels like a boy; other days, xe feels like a girl instead. Today, xe feels fantastic!’

Another illustration explains: ‘Stéphie wasn’t born in a boy’s body.

‘She’s a girl, and her body is hers. So, her body is a girl’s body.’

As well as Sandro/a and Stéphie, the book also features a boy wearing a dress, and a princess who rescues a knight and his two sons.

This is not the first time author Labelle has used illustration to make a powerful point about gender.

When not working as a substitute teacher in Montreal, Canada, Labelle is the author of ‘Assigné garcon’ (Assigned male), an online comic about a young trans girl.

“Ça déborde ! is available for order around the world from June 10.
