1 From the sixth pregnancy, parents can touch their stomachs and have a "conversation" with their babies. Studies have shown that a 6-month-old fetus can perceive external sounds.

2 train your baby's hearing. Let 0-4 months old babies listen to different sounds, such as the sounds of nature, vehicles, animals and so on. You can take your baby to listen to these sounds when he is full of energy.

3 train children's auditory discrimination. Children's poor auditory discrimination will cause little sound confusion and affect the effect of listening to lectures. Parents can let their children listen to different sounds when they are 5- 12 months old, and play games with their children to find the direction of sound sources, so as to enhance their hearing discrimination.

4 train children's auditory comprehension ability. Hearing is the second organ to obtain information, so children should not only hear but also understand. Therefore, parents need to talk to their children more and expose them to all kinds of voices. For children aged 2-6, parents can verbally arrange some simple tasks for their children to complete.
