Your 6-year-old comes home from a playdate reporting that Maya has two mommies. She wants to know how that's possible; you want to know how to respond. Keep things simple, says sexuality educator Deborah Roffman. "Kids this age know that there is a unique relationship called a couple: that two people have feelings for each other and choose to make a family together," she notes. Ask your child to name some couples she knows, then add some new information: "Sometimes grown-ups find that the person they want to spend their life with is a person of the same gender: a man with a man, or a woman with a woman. That's called being gay." There's no need to launch into a long explanation about homosexuality. The question is just about family constellations. When you look at it that way, it's easier to address.
