Argentina's government has granted a female identification card to a 6-year-old boy who has been dressing like a girl since age 4.

The boy was born Manuel but likes to be called "Lulu." On Wednesday, he received an amended birth certificate and a new ID with the change in gender.

It's the first case of a gender change on a document for a minor in Argentina since the approval of the country's groundbreaking gender-identity law last year.

The law lets people change their names and sexes on official documents without first getting approval from a judge or doctor.

The mother says her child's new name is Luana. After receiving the documents, she thanked those who, in her words, "trusted the identity of my daughter" and "respected her rights."
