Twin babies eat each other's burning hands. Netizen: Parents should pay attention when they are eager.

Oral desire period is a strange professional vocabulary for parents, but the baby's behavior must be familiar to parents. Babies' oral desire period is the main way for babies to satisfy various desires, such as sucking and eating hands. Moreover, medical observation believes that the craving period exists before the baby is born, and sometimes pregnant mothers can see that the fetus will also suck their fingers in the womb by doing B-ultrasound.

If the child does not develop normally during oral sex, it will cause the baby to eat his hands and chew his fingernails after oral sex. Greedy, smoking, drinking and nagging may appear when you grow up. It is not an accidental phenomenon, nor is it a bad habit, that the baby has a desire for oral sex before he is one year old. In this period of the baby, parents should strive for guidance. If parents do not pay attention to guidance, the baby will overcompensate in the future. In case of anxiety in the future, there will be many bad oral habits, such as sucking fingers and biting lips. Bad oral habits are one of the important causes of malocclusion, which will lead to bad changes in children's bones, muscles and teeth.

Sucking fingers will lead to obvious malocclusion in children after 3 years old, and will also lead to round jaws in front teeth. On this basis, it will lead children to have the habit of sticking out their tongues, which will aggravate the degree of mouth opening. Due to the contraction of buccal muscles during finger suction, the air pressure in the mouth decreases, which makes the dental arch narrow, the upper front teeth protrude, the lips open, the teeth are exposed, and there are unilateral rear teeth.

Biting habits: Many children will have the habit of biting pencils, skirts, corners and so on. This habit will lead to the formation of a small mandible in this area, resulting in a deep tooth coverage caused by the inclination of the upper front teeth.

Biting habit: The habit of biting the lower lip when children are 6- 15 years old will lead to the lingual side of the upper anterior teeth and the labial side of the lower anterior teeth, thus increasing the pressure on the lingual side of the upper anterior teeth and inclining the pressure on the labial side of the lower anterior teeth. It hinders the forward development of the lower dental arch and mandible, and depresses the front teeth to tilt to the lingual side in a crowded state, deeply covering between the upper and lower front teeth.

Tooth licking habit: children often lick their teeth loosely during tooth changing, forming the habit of licking their teeth. This forehead habit will increase the force of the lingual muscle on the teeth, which will lead to partial inclination of the teeth, and even lead to malocclusion when the gap between teeth is serious.

Unilateral chewing habit: Children's behavior is mostly due to a residual crown or dental caries in a back tooth. Will affect normal chewing. After a long time, it will form a unilateral chewing habit, which will lead to the child's mandible deviating to the healthy side, and the dental arch will rotate to the healthy side, causing the healthy side's mandible to face or reverse. The lower midline is also biased towards the healthy side. Lead to the child's face Xu Oh, there are two developmental asymmetries.

Many children's bad habits are caused by insufficient psychological satisfaction. Children's bad habits will lead to children's bad oral habits, and bad oral habits will also lead to children's face and teeth dysplasia.

Parents must help their children change bad habits and guide them correctly.
