There used to be an early education machine in the United States, but after growing up, the survey did not show a direct relationship with the improvement of children's intelligence, and later it was discouraged again and again. But personally, I don't think such a young child should touch him with instruments, but should be more realistic, such as grasping and touching with his hands. Everything you see with your eyes must be true. Excessive use of electronic products when children's eyesight is not well developed is definitely bad for children's eyes, because experiments have been done abroad before. If a child of 6-8 months can speak a foreign language, it will be easier to pronounce it when he grows up, but if it becomes a DVD, it will have no effect at all, which means that when such a young child is studying, he may study face to face, which is my personal feeling.
