A 6-year-old triplet who was born male but has lived as a girl since 18 months old has been told she can longer use the female toilet facilities at her school, Breaking Celebrity News is reporting.

However, in December, school officials told her parents that if she needed to use the toilet she would have to go to the boy’s or nurse’s bathroom.

“We want Coy to have the same educational opportunities as every other Colorado student,” her mother, Kathryn Mathis told ABC.

“Her school should not be singling her out for mistreatment just because she is transgender.”
