Skateboarding superstar Nyjah Huston was totally stoked to see video of a 7-year-old boy with cerebral palsy hitting the ramps with his mom ... telling TMZ Sports the clip is "awesome!!"
As we previously reported ... Avante Leaozinho -- who was diagnosed with cerebral palsy at 18 months -- had the time of his life as his mom pushed him around the skate park ... and the video quickly went viral.
We showed the touching vid to the 24-year-old X Games champ outside Halsey's Halloween party over the weekend .
