Jan Brzechwa was the creator of modern children's poetry. His style, humour and way of structuring poems have found many imitators in the children's literature of the second half of the twentieth century; even those who did not imitate Brzechwa show signs of this influence. Brzechwa departed from the traditional association of poetry with folklore and rejected its moralistic tone. Instead he directed his attention towards children themselves, their language and their own, spontaneous creativity. For instance, the humour of the poem At the Stall relies in part on the repetition of a set formula, just as in a children's 'dipping' rhyme. The effect is comic, as are other kinds of children's wordplay which Brzechwa also liked using. The poet employs simple words to write about ordinary things, things that children see around them.He writes about them tongue in cheek, with a light and witty touch.
