France is proposing to put an end to labelling children's guardians as "mother" and "father" on school documents.
The change was part of an amendment to a new draft education bill. Supporters are hoping it will put an end to discrimination against same sex parents, reports The Telegraph.
However, critics are arguing the amendment "dehumanises" parenthood, and may lead to arguments over who gets to be "parent 1."

The amendment was passed by French MPs on Tuesday evening.
"This amendment aims to root in law children's family diversity in administrative forms submitted in school," said Valerie Petit, MP for the majority REM party of President Emmanuel Macron.
"We have families who find themselves faced with tick boxes stuck in rather old fashioned social and family models. For us, this article is a measurement of social equality."
Conservatives are horrified by the proposed change.
"[The amendment is] a frightening ideology, which in the name of limitless egalitarianism promotes removing points of reference, including those regarding the family," said Conservative MP Fabien Di Filippo.
The amendment is not out of the woods yet, as it could still be rejected by the majority Right Senate, reports The Telegraph.
It will then return to the National Assembly for a final reading.
