Sara Holbrook most commonly writes poetry about childhood experiences and the emotions that are likely to be results from them. Some of her poems are based on her own familiarity of growing up. "I write about two things mostly- what I know and what I wonder about. But mostly I write about things that happen in my own life.".
She began writing poetry for her daughters Kelly and Katie when they were young. She would write the poems down in a book and have the girls illustrate them. The inspiration for her poems also comes from the problems that she has witnessed the girls go through. Now that her daughters are adults, she continues to write to help her to understand her life, and the world better. .
A great majority of Sara's poems contain feelings of insecurity, helplessness, and loneliness. In the poem A Different Fit, the speaker expresses how miserable it is to not be part of the "in crowd", and how one can feel as if they stick out like a sore thumb or in Sara's example "like an alien standing out in neon socks." The speaker in Blueprints conveys the uncertainty they feel as to what they will be like when they become adults. On the Rise also suggests the apprehension of not being able to make the transgression from the early stages of life to adulthood. .
Sara uses many forms of figurative language in writing her poems. They often contain metaphors, similes, hyperboles, alliteration, imagery, rhetorical questions, irony, and what could be classified as slang. When writing poetry for children, about children, the poet has to be careful in choosing the vocabulary. In order for the poem to be successful they have to develop a language that kids can relate to. In Appearances to the Contrary, Sara uses the phrase boo-boo lip to describe the pouty faces that children are so well acquainted with. She abbreviates the words "come on", and "is not" to "c"mon", and "ain't" in the poem Two By Two.
