Whose mother's child do you know who isn't smart? They are intelligent, but I put more emphasis on nurture vs. nature in most any scenario. I know they are capable of knowing much more, but without guidance I'm feeling a bit incompetent of teaching them any foreign language--an area of study that I place a lot of weight on. Since I have some foundation in Russian, I thought it would be an easy place to start. Now, without material, I'm having my doubts.
