Remember the “mommy wars”? The term started to gain popularity in the early 1990s and was the subject of magazine features, blog posts, and even a 2006 book with essays by high-profile writers like Jane Smiley and Susan Cheever. In the beginning, the term referred largely to conflicts between moms who worked for pay and those who stayed home with their kids. But over time, it expanded to include a whole host of “rivalries between mothering philosophies and practices,” from sleep training to breastfeeding to screen time to discipline, Jenna Abetz, a professor of communication at the College of Charleston who has studied American motherhood, told Vox. “More than ever, it feels like moms are fragmented into these smaller and smaller camps and forced to sort of justify and defend their own parenting choices.”
