A heartwarming video shared on TikTok shows the moment a special needs kindergartener decided to ditch his wheelchair and walk across the stage for his graduation ceremony.

Finley “Finn” Williamson was diagnosed with Noonan syndrome at two years old, according to People. The genetic disorder can cause skeletal malformations, short stature and mobility issues.

Earlier this week, Finn’s mother, Mackenzie Williamson, posted the sweet video of her son deciding “last minute” that he wanted to walk to receive his diploma. The video shows 6-year-old Finn walk across a bridge to his teacher with his father’s help as his teacher wipes away tears. The clip, which Williamson described as the “most proud moment of my entire life” has more than 200,000 views on TikTok and has sparked a lot of feels.

“This little man doesn’t even know the impact he’s making, not only to his classmates but to people around the world. What an amazing moment!” one TikTok user wrote.

Finn, who has since turned 7, is now walking after years of physical therapy, according to his mother.
