Figurative is the opposite of Literal. Its a system of analyzing language. Vivid, Expressive and imaginitive statements that are used to exagerate or alter the actual meaning of the words.
For example, the sentence "The ground is thirsty" is partly figurative because the word "Ground" has a literal meaning, but the ground is not alive and therefore neither needs to drink nor feels thirst.
And I am not sure what you mean by using it for a baby. Like, Bun in the oven? Not a literal bun in an oven.... ^_^
Its just language that gives yoir wrighting feling and meaning. Like: The baby is a beauty, when I look at him I feel like I'm going to melt. (Example of exageration) The babys skin is like a rose petal (example of a simily) And stuff like that, but like in your own way.
like im using my nephew for my paper and we have to have examples of figurative language to describe the thing we chose and i dont know how to use figurative language on my nephew, hes 4 months old.
