Agreeing with the above comment on Treasure Island. Given the ages of your children, you might also consider waiting on Robinson Crusoe. I plan on saving that one for high school for age 12-14. Also agreeing with what others have said about using the SCM booklist to structure your family read aloud list, and then building your children’s independent reading list based on all other recommendations “out there” (i.e. books listed in Honey for a Child’s Heart, missceegee’s book lists, Sonlight recommendations, etc)
Personally, I wouldn’t miss reading Trumpet of the Swan aloud to your children – it’s too good not to enjoy yourself. Also you will miss out enormously if you don’t add Little Lord Fauntleroy to your list! I loved that one (especially loved the mother…what a woman – what love, gentleness, forgiveness and self control she shows!)
