Cummings decided to become a poet when he was still a child. Between the ages of eight and twenty-two, he wrote a poem a day, exploring many traditional poetic forms. By the time he was in Harvard in 1916, modern poetry had caught his interest. He began to write avant-garde poems in which conventional punctuation and syntax were ignored in favor of a dynamic use of language.
Cummings composed poetry as a child, writing a poem a day from the age of eight until twenty-two. He experimented with form and language to create his unique avant-garde style, sometimes employing invented words, turning nouns into verbs, and avoiding standard use of punctuation and capitalization.I would bet that this is one of Bialosky's (unattributed) sources. The language is changed enough so it doesn't seem like plagiarism of language, and the ideas are standard enough (everyone knows that about Cummings). Ironically, the biographical detail here is the most specific thing.
