​An elementary school in Nova Scotia has decided to cancel Mother’s Day and Father’s Day celebrations out of sensitivity for non-traditional families.

United Press International reports that Astral Drive Elementary School will instead only recognize a more inclusive holiday: International Day of Families, a U.N.-established festival that’s meant to recognize single-parent and same-sex family homes, too. The school had celebrated all three starting two years ago.

But this year, students weren’t allowed to make cards specifically for Mother’s Day, said one parent, and were instead asked to write the names of people who have supported them. The province’s education minister explained that schools are free to choose how to recognize holidays and which ones to celebrate.
