A private school in Manhattan is encouraging students to stop using the words “mom,” “dad,” and “parents” and instead use more “inclusive language.”

“Families are formed and structured in many ways. At Grace Church School, we use inclusive language that reflects this diversity. It’s important to refrain from making assumptions about who kids live with, who cares for them, whether they sleep in the same place every night, whether they see their parents, etc.,” the guide from Grace Church School in NoHo says.
