I have watched 1-2 years old children talk. Many of these little children are multilingal. Many have learned to swim, climb (furniture and fence rails). Many can put round pegs in round holes. At 1-2 years of age, children CAN THINK and DEVELOP physical and language SKILLS.
Perhaps multilingual skills and life-saving skills such as swimming, tumbling, ... should be taught as early as possible. BEFORE CHILDREN GO TO SCHOOL and become robots.
