Three-month-old baby's eye vision is still in the mature stage. It must be harmful to expose him to radiation too early. Don't say you can train them to think. You don't say! He is still in the cognitive stage and has no time to think about things on TV. Before the age of three or four, he can try to avoid radiation on the screen, so he can buy a projector for some early education. Everyone knows some things, such as affecting their eyesight, not conducive to emotional development, not conducive to the cultivation of children's social skills and so on. However, in real life, parents always push their children in front of TV and other electronic devices for various reasons.

Excessive use of electronic devices will take up precious brain development time of the baby, leading to cognitive, language, social skills, emotional control and other developmental delays. Not too long. The reality is that the baby doesn't understand either. There is no point in showing him TV except being affected. He is only three months old, and his body is still tender. It's best to stay away from TV and computer. Now childhood leukemia is closely related to the radiation of these electronic products. In fact, it is not suitable for premature contact with electronic products. If you don't want to or can't strictly limit it, you should control the time of watching TV, don't follow your baby's temperament, and show it to him for a long time if you like, which will affect your baby's vision development.
