In an essay for the publication, the model detailed why she doesn't want to reveal her baby's sex. "When my husband and I tell friends that I'm pregnant, their first question after 'Congratulations' is almost always 'Do you know what you want?' We like to respond that we won't know the gender until our child is 18 and that they'll let us know then," she began her essay. "Everyone laughs at this. There is a truth to our line, though, one that hints at possibilities that are much more complex than whatever genitalia our child might be born with: the truth that we ultimately have no idea who — rather than what — is growing inside my belly," Ratajkowski wrote. "Who will this person be? What kind of person will we become parents to? How will they change our lives and who we are? This is a wondrous and terrifying concept, one that renders us both helpless and humbled." Baby's First Halloween!

The mom-to-be also explained her feelings on having both a son and a daughter, and said she doesn't "necessarily fault anyone for these generalizations" about gender, as "a lot of our life experiences are gendered, and it would be dishonest to try to deny the reality of many of them." "But I don't like that we force gender-based preconceptions onto people, let alone babies," Ratajkowski said. "I want to be a parent who allows my child to show themself to me. And yet I realize that while I may hope my child can determine their own place in the world, they will, no matter what, be faced with the undeniable constraints and constructions of gender before they can speak or, hell, even be born." Ratajkowski tied the knot with actor and producer Bear-McClard, with whom she had only started cozying up in the previous few weeks, at City Hall in New York City in a surprise 2018 ceremony.
