Anyone else think that Katie was an airhead??

I like this movie and watched it as a child. I recently rented it and still enjoyed it. It's one of those disney classics that should never be forgotten. But I'd like to say some things about Katie. While the actor who played her was a good actress, the character of Katie was an airhead. She seemed like a good wife and mother, but yeah, her character was an airhead, as was specified several times during the movie.
