A couple in the US has made the decision not to tell people the gender of their two-year-old child, as part of an effort to bring them up in a gender-neutral environment.
Kyl and Brent Myer are part of the Gender Creative Parenting movement and instead of referring to their toddler Zoomer as a girl or a boy, the child is referred to as a "theyby".
The couple uses the pronouns of 'they', 'them' and 'their' when talking about Zoomer and no one outside of their immediate family knows the toddler's sex.
In her blog Raising Zoomer, Kyl said: "The sex does not tell us anything about the child's personality, temperament, favourite colour, dietary preferences, sense of humour, attitudes toward climate change, or any of their other unique traits.
"Just like the fact they have two arms doesn't tell us anything else about them, except they have two arms."
They are instead letting Zommer choose their gender, which Kyl expects will likely happen by the time they are three or four.
