Children need to practice reading skills by reading aloud. This helps them develop fluency. A child can read to a sibling, a pet, their toys, and even plants. Their reading becomes enjoyable when they have someone or something to share in the experience.
When I taught second grade I set up an experiment. My hypothesis was that plants that are read to do better than those that aren’t. I had the same type of plant (pathos) in opposite sides of the classroom. One plant was read to daily and one was not. Students clamored to be the reader. They kept a notebook of their discoveries. It may have been happenstance, but the plant that was read to flourished in contrast to the plant that did not have a child read to it. I’m not a scientist, but I am a reading teacher with a creative mind. My experiment was a success! It got students reading and writing.
I imagine that a sibling or a pet would love the attention. Anything that encourages reading is a good thing.
