I received a free digital copy of "Babble!" by Caroline Adderson and illustrated by Roman Muradov in exchange for an honest review of the work.
"Babble! And How Punctuation Saved It" toes the line between long picture book and early chapter book, with the most appropriate setting to read being aloud and on a parent's lap. The aural element of punctuation is missing if a child were to read this on their own without prior instruction on punctuation. The more dynamic word choice, coupled with the foundational explanations of punctuation, puts "Babble!" as a book to be read with a grownup or an enthused student returning to the basics after mastery.
Punctuation can be difficult for beginning readers, especially if their favorite punctuation is the question mark. And more so when it's preceded by, "But why does it matter?" The start of this book could be difficult for this audience. A stranger pops into a "once upon a time" village where no one has any punctuation to put meaning to their constant babbling. The narration takes on this monotonous quality for quite a few sections before punctuation is introduced--making the exposition almost frustrating to read. This could be either a motivator or demotivator for children reading on their own, depending on their feelings toward reading. Reading aloud with a caregiver could be a more engaging way to experience the text.
As the stranger introduces punctuation marks one by one to the villagers, as their need arises, those punctuation marks are printed large and red in the narration. They stand out against the black text and, by the end, create a visual on the page for how integral punctuation is to language. That use of color also bookends the story. The black text opens a door (maybe a portal?) into the village and their babble. On the final pages, the red punctuation covers the page as the stranger leaves just as miraculously as she came in. My digital copy of "Babble!" had some issues with scaling, so I cannot comment further on the illustrations beyond the use of color.
At around 48 numbered pages, this is a longer read for the child who is starting to learn punctuation. I can see "Babble!" used as a classroom book, with the teacher using small sections to focus on one type of punctuation. The "real world" applications for punctuation are readily understandable for young readers. However, these examples are expected and unimaginative such as the "Let's eat Grandpa!" explanation on comma usage.
"Babble!" ends with afterword, or more appropriately, a glossary of more advanced punctuation for the young reader wanting to know more. The explanations of dashes, ellipses, and semicolons are thorough and include short examples within their definitions.
