A new law in Norway means children as young as 6 years old can choose their gender.
Until July, Norway was one of 32 European countries that required people to undergo irreversible sterilization before their gender change would be legally recognized.
Ten-year-old Anna Thulin-Myge is one of nine children who have taken advantage of the new measure. It allows Norwegian children to self-identify as male or female with their parents' consent.
"In some weeks, I'm going to have a new passport and then it's going to say 'F.' My name will be Anna, and that's going to be great," the transgender child said.
"I think it's a beautiful thing that Norway can finally recognize her as the girl she actually feels she is," Siri Oline Myge, Anna's mother, said.
So far, Norway has not refused a single gender reassignment application for an adult or child. There is no requirement for surgical or psychological intervention or approval.
Legal officials say the process is simple: applicants just go online and fill out a form.
