As Constance Hale says
The playful language found in childrenâ€™s books comes naturally to us when we are young.
As we mature, our delight in sounds becomes less visceral.
[W]e often lose the childâ€™s love of chaotic vowels and knocking syllables. Even when writing about poetry, we bog down in the language of academia. Our sentences get longer as we pile up clauses and struggle to state a thesis. Then, in our professional lives, we get tangled up in bureaucratese and forget our innate ability to play with sound and sense.
