I have the older children take turns reading aloud during our history family book, but not every day for each one, and I still do a lot of the reading. We just pass the book around. The middle school & high school ones have additional books to read for the given time period, but I don’t often have them read aloud from those…..maybe just once a week and only a couple of pages so I can check their reading.
Sometimes, I just have the oldest two read the Bible to each other. I can hear it while I’m doing something else, so I can tell if someone is struggling with a passage.
When my kids were younger and perhaps not terribly fluent at reading aloud the materials I used for family books, I just had them read aloud portions of their literature book or science or something else every couple of days. They read aloud to me every day in the early days of learning to read, but those sessions were relatively short.
