I mean it's well known that you can teach young children complex cognitive skills. There are preschoolers with high competence at difficult musical instruments and sports skills for example. I don't see, and haven't found in relevant reading or experience, any way reading that early is more valuable to the child than anything else they could be taught. All it really announces is what skills the most influential adults in the kid's life value.
