I never had my kids read aloud when they were younger, except when they were first learning basic phonics in preschool. They are now proficient readers at age 9 and 10. If a child is struggling with fluency, it is worth working on at home, but I would probably separate out the fluency practice from reading stories for pleasure, and just do 10 min. per day at the most. When I tutored kids reading for fluency in a school, I pointed to the error when they were done with a sentence, and said "that word is "clear", and had them re-read the sentence saying the correct word. This would be extremely annoying to the child if you were doing it with pleasure reading.
