FOUNTAIN, Colo. (KKTV/CNN) - A 6-year-old transgendered student in Colorado is at the center of a civil rights controversy.

The parents of the first grader say their child is being discriminated against at school. They plan to hold a news conference Wednesday to tell their story.

Six-year-old Coy was born a boy, but now lives life as a girl.

"When she was about 18-months-old and started to talk, as soon as she was able to, it was that she was a girl and she liked girl things," said her mother Kathryn Mathis.

Coy is now in first grade. She was going to Eagleside Elementary School in Fountain, where she was treated as a girl, and used the girls' bathroom.

"After she did transition and was able to live as a girl, as her true self, the difference was amazing. Her anxiety went away, the depression went away and she was finally happy," said Mathis.

The family then got a letter from the school district. It says that Coy was born a male and "at least some parents and students are likely to become uncomfortable with his continued use of the girls' restroom."

Coy is now homeschooled.

A lot of parents in the neighborhood didn't want to talk, but one mom says she admires the parents for sticking up for their child, but ultimately agrees with the school.

"From a parental standpoint, I think that the school district did the right thing," said Candance Toscao.

Affiliate KKTV called the school district for comment, but the calls were not returned.
