Tea was hit by a 15-year-old driver while crossing the road 10 days ago, suffering critical injuries including a cracked skull.
She is now barely able to see, struggling to eat liquid food from a spoon and her family is unsure how bad her injuries are.
"We're devastated. She's the love of our life," Tea's aunt Tea Brimigion says.
Tea's been operated on at Vailolo Hospital on Tonga's main island of Tongatapu and showing signs of progress.
