DS1 is nearly 6 1/2 and can read fluently now. He brings home four books a week in his bookbag and they are usually quite long. Up until last week we were getting him to read aloud to us in the evenings, then reading a chapter of something more interesting, like Harry Potter, with him. Trouble is, it's very time-consuming. Would it be okay just to let him read the schoolbooks on his own, so that we have more time at bedtime to read other books with him? Or is this a grave dereliction of duty??
