Why does the baby's lower lip tremble?

When a baby first appears in this world, he or she will do very few subconscious actions. However, if you find that your baby can do a lot of things, you may be very happy. But you also need to pay attention to the baby's actions, because sometimes the baby may do this because he or she is uncomfortable. Just like you found that your baby's lower lip is trembling, do you know why?

1. Difficulty falling asleep and restless sleep. Night terrors and crying at night are signs of calcium deficiency in babies. Newborns who are calcium deficient will often wake up suddenly at night and cry incessantly.

2. Night sweats. The head sweats profusely after falling asleep, and the sweating is more obvious after crying.

3. Abnormal temperament. Babies who lack calcium will have strange tempers and often show symptoms such as irritability, crying, and restlessness, making them difficult to look after.

4. Late teeth eruption and uneven tooth arrangement. Some babies still have no teeth when they are one and a half years old, or their teeth are underdeveloped, malocclusion is incorrect, the teeth are uneven, loose, or fall out prematurely.

5. Bald circle on the pillow. Babies who are calcium deficient are prone to sweating, and usually the hair on the back of their head is worn away, forming baldness on the back of their head. Baldness on the occipital area may partially reflect calcium deficiency, but it is not an absolute condition.

6. Delayed closure of the anterior fontanelle. The anterior fontanelle usually closes at the age of 1 to 1.5 years. Babies with calcium deficiency often still do not close after 1 and a half years old, resulting in a square head.

7. Growth retardation, late learning to walk, and bone and joint deformities. Most children who are calcium deficient learn to walk at around one year old, or they may have "X" shaped legs or "O" shaped legs due to soft bones, loose and weak muscles, and leg bone pain.

8. Relaxation of muscles and tendons. If calcium deficiency is severe, the abdominal wall muscles will lead to relaxation of the intestinal wall muscles, which may cause gas accumulation in the intestinal cavity and form a swollen abdomen like a frog's belly. If the tendons of the spine are loose, hunchback, pigeon chest, and sternum pain may occur.

9. Beaded rib cartilage hyperplasia. When newborns lack calcium, the cartilage of each rib proliferates and connects like beads, often compressing the lungs, making it difficult for the newborns to breathe and making them prone to bronchitis and pneumonia.

10. Calcium deficiency can also manifest as poor mental state, loss of appetite, lack of interest in surroundings, convulsions, mental retardation, decreased immune function, etc.

The above are the symptoms when there is a problem with the baby's physical health. The baby's lower lip trembling is one of them. If parents find the baby's abnormal behavior, they should know to supplement the child's nutrition or go to the relevant department to find out more. Only in this way can the baby grow up healthily.
