The sibling’s behavior is not always ideal, but this is consistently shown in a negative light when it should be. This includes Peter telling his brother to “shut up” and celebrating believing they can do whatever they want when they see the professor they will be staying with is older. Similarly, Edmond is often ill-tempered, dishonest, unkind to his siblings, etc. Fortunately, each of the characters grows tremendously, especially Edmond.
At one point when the great showdown is approaching the white witch calls for all who serve her. All types of Narnia creatures are mentioned, including ghouls, specters, hags, werewolves and others. There is hardly any focus on them besides being mentioned and they are clearly shown as evil, but good to know it is there. This part is also an uptick in the intensity of the book, but the author is cautious, knowing his readers.
There are a few other random things to know about. One of the good animal characters pulls a mug of beer from a huge barrel. There is also an instance of smoking a pipe. The description of “fat” is used once and at one point Edmond says that something is “just like a girl”.
One last thought. There is certainly a difference between your child reading this book and seeing the movie. A child who is ready for the written story may not quite be ready for the wickedness of the white witch on the big screen. We suggest you prayerfully think through this and potentially even pre-watch at least some of the movie before allowing a young or sensitive child to see the movie version.
