I promise it’s not that hard. You could say “Yes, Johnny, sometimes boys do wear lipstick and that is perfectly okay. You can wear lipstick too if you want!” Or you could say, “Why yes, Sarah, she is wearing a bowtie. Girls and boys can both wear bowties. Would you like one?”

Or, if your child is a savant, you could even say “Yes, Tabitha. While we are often presented with the myopic notion that gender is biological in nature, it’s actually a socially constructed, performative/discursive system that creates hegemonic power within society and varies across cultures, time, and anthropological space. You’ll learn all about that when you go to college on a full scholarship, become a gender studies major, and read Judith Butler and Michel Foucault en route to writing your thesis!”
