“Greyson Mathews KEEPS CRUSHING IT!” Jenni “JWoww” Farley captioned the Dec. 2 Instagram video of her and 4-year-old Greyson doing some reading exercises. One by one, Greyson reads out the words on the flashcards to say, “My mom is fun.” This accomplishment brings a huge smile to the young boy’s face, and everyone around him cheers. “I cry every time I watch this,” added JWoww, who, in 2018, shared that her son was diagnosed with autism.
