A four-month-old baby can go to an early education institution. They are relatively systematic, but I think early education at home can also be done. When my daughter is basically four months old, I will tell her stories, that is, read some Grimm's fairy tales, the Arabian Nights and so on, and then read some biographies of celebrities. In the evening, I basically recite some poems and three-character classics to her. If I persist, I will see a surprise. At this time, after the child can speak, she can begin to recite them. Now that I'm in grade two, I don't need to rush my study. I can read all afternoon by myself, and I can try Qiao Hu for online early education. Not bad, listening to English children's songs is also very useful. Anyway, if you have a child, even if you just chat with him more, chatting can promote the child's brain development. You can try it and wish your baby health and happiness.
