"For a small but growing cohort of parents — ones who see gender as a spectrum rather than a binary — the unisex movement of the ’60s and the 'gender neutral' parenting trends that have followed have come up woefully short."

"For them, society’s gender troubles cannot be solved by giving all children dolls and trucks to play with or dressing them all in the color beige; the gender binary must not simply be smudged but wholly eradicated from the moment that socialization begins, clearing the way both for their child’s future gender exploration and for wholesale cultural change.... 'I knew that I wanted to parent like this years before I ever got pregnant'.... The point was not to have a genderless child but one who comes to an understanding of their gender — whatever it might be — in an environment where colors and objects and activities are not slotted into the arbitrary and binary categories of 'girl' and 'boy'... 'We were just like, Let’s make it look like a rainbow exploded in this house,' Myers explains of wanting to provide Zoomer with all available options, rather than limiting options to those deemed to be gender neutral....

"Parents do not shy away from describing body parts, but are quick to let children know that 'some people with penises aren’t boys, and some people with vaginas aren’t girls,' as one mom told me.... Once Jacobs, whose partner identifies as nonbinary, selected a day-care provider, she sent an email further explaining her stance and asking that the caregivers — who would certainly be changing Scout’s diapers — not share Scout’s anatomy with anyone else. 'It was a little hard at first,' says Jenny Lee, who was one of Scout’s teachers. 'Not because we had any sort of philosophical challenge with it — we were really behind what they were doing — just because of the grammar.'...

"A common fear among gender-open parents, then, is that their family will be isolated, cut off from people for whom interacting would require just too much cognitive work. 'It has been challenging,' says Jacobs.... 'I just think parenting in general is a social experiment,' says Myers. 'That said, I just don’t think I could ever parent my child within a binary. So, like, is this an experiment? I don’t know.'... 'Zoomer is going to have a gender,' Myers says. 'They are going to let us know what their gender is, and it will probably happen when they’re 3 or 4. And we can all just get onboard, you know.... But now that we are parenting this way, it’s actually very possible that Zoomer will be gender nonconforming because we are not raising them to conform to a binary gender.' One of the most nuanced pushbacks Jacobs has encountered is the point that they/them actually is a gender identity for some people and that by using it, she is in fact assigning a gender to which her child may not relate...."
