Answer:
I would say that the figurative language that is best represented in this excerpt is Imagery.
Step-by-step explanation:
Imagery is used to describe actions in such a way that it appeals to our physical senses. It creates in the reader a visual representation of the actions that take place in the story. In this case, by describing the subject as a person that enjoys motion, light, colour, music and textures, we can make a colourful picture of the baby. We can imagine her as a happy, joyful baby. Also, the author says that "she blew shining bubbles of sound" and we can picture her as a fun, smiling baby. Everything the author says about the baby makes the reader build a better idea of her by appealing to their physical senses.
