What are the characteristics of a baby's voice? How to protect your voice?
Children's vocal cords and other vocal organs are in a state of growth and development before the age of 6. The child's throat cavity is narrow, the glottis are narrow and short, and the vocal cords are short and weak, thin and not tough enough. Therefore, children's voice is higher than that of adults, but children's vocal range is narrow and vocal cords are prone to fatigue. If the child's pronunciation takes too long, the pronunciation method is incorrect, or he often cries loudly, it will hurt the child's vocal cords and make them thicker. 1. Be careful not to let the baby cry loudly for a long time in infancy. If you don't pay attention, it will affect the development of vocal cords over time. 2. Educate children to protect their vocal cords. In addition to positive education and stopping loud noises, the exemplary role of teachers and parents should not be underestimated. Of course, we don't necessarily ask for soft words, but it's not good to scold loudly. Some teachers and parents think that sound can "shock" children, but they don't know that children will raise their voices and imitate them.

3, teach children to sing, pay attention to the characteristics of children, the starting tone should not be too high, the range should not be too wide, do not teach adult songs. When the throat is tired or inflamed, singing should be forbidden until it is fully recovered.

4, don't sing against the wind, drinking cold drinks after the song will also damage the vocal cords.

5. The volume of children singing and reciting should not be too loud and the time should not be too long. The air must be fresh and moist in places where singing and recitation are performed.

6. Pay attention to the nutrition and hygiene of the diet. Foods that are irritating to the vocal organs, such as peppers, should be restricted.

7, pay attention to keep warm: avoid catching a cold. Pay special attention to keep warm in winter, try not to wear low-necked clothes, and keep your neck warm to avoid catching cold in your mouth and throat. Catch a cold will aggravate the swelling and congestion of vocal cords. In addition to paying attention to changing clothes and bedding with the weather, taking part in some baby's outdoor activities in moderation is also of great benefit to the healthy growth and development of vocal cords.

8. Children with chronic tonsillitis, hyperplastic hypertrophy, and chronic paranasal sinusitis, because secretions are attached to the throat wall, children often involuntarily make a "giggle" sound, which will damage the vocal cords over time. Some children with poor hearing will get into the habit of talking loudly and damage the vocal cords. Severe vocal cord injury in childhood may affect the development of vocal cords, and it will not be restored until the child's voice changes in youth.

9, children must not stay up late, life should be regular, to ensure adequate sleep.
