Five-year-old Kayleigh Kulage has been undergoing dialysis since she was a baby. Because she was too sick to attend school, preschool teacher Robin Mach came to her.
When the young Missouri girl qualified for a transplant this year, her teacher stepped in to help, offering her kidney to the young girl.
Discovering they were a perfect match, Kayleigh and her teacher went through a successful, six-hour surgery at a nearby hospital.
Kayleigh and her family are now planning their first-ever vacation, and Mach is back teaching.
