Her dream came true when the office manager at her school told her the good news last week.
The video was first posted by the school's office manager, Jackie Alexander. "She knew (Tannah) would want to know right away because she had been so anxious", Alexander wrote.
Alexander said, "I grabbed her shoulders and said, 'Have you heard the news baby?"
Tannah was so happy she couldn't let go of Miss Jackie.
"A dear family I know has been fighting for as long as I can keep in mind to adopt 3 of their foster children ..."
"We just feel like we're ordinary people that are taking care of three children that we love and we want to be part of our family", she said.
"I just thought, 'Oh my gosh, we've done the right thing, '" Fisher said. She told KSL she wanted to share the video of Tannah to show that there's still positivity in the world. "You get your forever family", said Alexander. Jennifer Fisher says "I just idea gracious, my gosh. A moment needed after waking up to another morning of devastating news on TV ... but a sweet reminder today that life can be and still is lovely in spite of it all".
"There's a lot going on in the world and there's a lot of sadness that we see, but you know what?" Tannah's moment of unbridled joy quickly turned that around.
"This is like the biggest thing that's ever happened to me", Tannah Butterfield told KUTV.
According to the study, more than 60 percent of kids who are never adopted will be in prison, homeless or deceased by the age of 19.
A similar study in 2011 by the Brookings Institute went further, arguing Congress should make adoption easier for potential families.
