Biting your lips is a bad habit. Because after a long time, the teeth will protrude outward and become protruding teeth. Protruding teeth not only affect the sound of chewing food and speaking, but also are very ugly. Therefore, children should not bite their lips. Before helping children to quit this bad habit, we should first examine whether we have neglected their emotional requirements and the environment around them (whether there are communication problems with children and teachers in kindergarten, whether parents' attitudes towards discipline are consistent in the family, etc.). ). After adjusting the external environmental factors, we might as well try the following methods:

1. Ignore that you need to adjust your mentality. It's really no big deal for children to bite their lips. Ignore the child when he bites his lip. Parents are too nervous or have improper correction methods. On the contrary, it will increase children's psychological burden, strengthen children's awareness and create a vicious circle. Many children's actions are often unconscious You can also shift your child's attention to other aspects, such as playing toys, reading books and playing games. And let the child talk and relax his lips.

2. Correctly guide 3-year-old children to have a certain understanding ability and can guide them through language. For example, "you will have your third birthday soon, and you will be one year old after your birthday." Biting lips is made by babies. I can't do this anymore when I am old! " Or tell him that biting his lips for a long time is ugly, deformed and inconvenient to eat.

3, rewards and punishments clearly specify a time period for children, how much time not to bite their lips, give praise and material rewards, such as buying children's long-awaited toys. If the child bites his lips, give him punishment, such as not watching cartoons.

Biting your lips at the age of 20 is a personal habit, it doesn't matter. As long as you don't pay attention to this thing often, there will be no problem! It has nothing to do with nerves!
