A four-year-old autistic boy, Darby, in Lincolnshire, England, adorably laughs and speaks for the first time as his mom teaches him how to count with her "spidey fingers."

Darby was learning how to count on July 9. While he laughed and during his lesson, he suddenly said the word "again," a breakthrough for him and his family.

" I [...] ran [my fingers] towards him and he laughs adorably and then says ‘again’ which was a breakthrough as he’d never said it before! [The] cutest funniest laugh that won’t fail to make you laugh and smile, his mom said.
