Secondly, parents usually read more books to their babies. Many parents don't understand. They think that the baby is young, the brain is not fully developed, and the communication between parents and him is "casting pearls before swine". Actually, it's not. Although the baby can't understand his parents' words for the time being, he can learn to speak by looking at his parents' mouths often. After a long time, he can also promote the development of hearing and play a very good role in the development of the baby.
The third point is to take the baby out often. The baby's physical development is a gradual process. In this process, the more stimulation is given to the baby, the faster the baby develops. So don't be afraid of your baby's poor resistance and don't take your baby out. Doing so will only make the baby's health worse and worse. Moreover, diversified external stimuli can make the baby's vision, hearing and smell develop better, so parents must take their baby out more.
