I love my straight female friends, but watching them divvy up parenting responsibilities with their baby daddies drives me bonkers. These are women who attended fiercely all-girls’ schools, watched Buffy, and serve on women-in-the-workplace committees. They married groovy guys with hip glasses and evolved into counterparts of smart, savvy couples. But then something went awry: They slipped into sexist models of parenting. As a queer woman in a two-mom family, it kills me to see my lady friends doing far more than their share of the work.
