STOCKHOLM — At an ocher-color preschool along a lane in Stockholm’s Old Town, the teachers avoid the pronouns “him” and “her,” instead calling their 115 toddlers simply “friends.” Masculine and feminine references are taboo, often replaced by the pronoun “hen,” an artificial and genderless word that most Swedes avoid but is popular in some gay and feminist circles.

In the little library, with its throw pillows where children sit to be read to, there are few classic fairy tales, like “Cinderella” or “Snow White,” with their heavy male and female stereotypes, but there are many stories that deal with single parents, adopted children or same-sex couples.

Girls are not urged to play with toy kitchens, and wooden or Lego blocks are not considered toys for boys. And when boys hurt themselves, teachers are taught to give them every bit as much comforting as they would girls. Everyone gets to play with dolls; most are anatomically correct, and some are also black.

Sweden is perhaps as renowned for an egalitarian mind-set as it is for meatballs or Ikea furnishings. But this taxpayer-financed preschool, known as the Nicolaigarden for a saint whose chapel was once in the 300-year-old building that houses it, is perhaps one of the more compelling examples of the country’s efforts to blur gender lines and, theoretically, cement opportunities for both women and men.
