The world's coolest mother managed to capture on camera the moment she surprised her 14-year-old daughter, who came out as transgender years before, with her first dose of hormone therapy.

"Today after waiting 2 1/2 years she finally got her estrogen," Erica Maison wrote. "I picked it up while she was in school so she had no idea. We have been waiting months for the readiness letter to be finalized and sent to Chicago, so had no idea on a timeline of when it would actually happen. Sorry I had to stop recording because we were both blubbering sobbing fools. September 24 is a day I will remember for the rest of my life."

Today, in an interview with Buzzfeed, Erica said that Corey has always loved high heels and makeup, but it wasn't until they came across a video of YouTube star Jazz Jennings that everything began to make sense.

They immediately booked an appointment with the gender clinic at Lurie Children’s Hospital in Chicago, where Corey received a puberty suppressing implant. The family had been waiting for an OK from her team of doctors to start hormone therapy, and the second she turned 14, they got the go-ahead.

“I think one of the biggest issues with our society today is that people just don’t understand what being transgender actually means," she told the website. "I want people to watch this video, and see the raw emotion of a transgender child that can finally live her life the way she feels inside. I want people to see this, because maybe it will open their eyes. Open their eyes to anyone who’s different. Maybe make them realize that people who are transgender are people just like them, but also people that are at much higher risk for violence and ridicule, over something they had no choice in. I promise you that no child wants to be made fun of, no child ever wants to be hurt, or picked on. No child would ever choose to be transgender, it is 100% how they are born.”

Not only is this video worth watching again, it's worth sending to all of your friends/family/that TA who won't stop emailing you about missing assignments, because everyone needs to see it.
