The girl's mother, Stacy McGough, told Dallas-Fort Worth television station KXAS that after seeing Winter for the first time, McKenna started wearing her hearing aid.
McKenna says of Winter, "She's not so shy to show her stump, so why should I be shy to show my hearing aid?"
McKenna has seen Winter six times in the last two years. She's even watched Winter's trainers fit the dolphin with a prosthetic tail. In McKenna's words, "She's helped me in not being afraid to be different."
Winter lives at the Clearwater Marine Aquarium.
