Having a baby should be a happy thing, but some parents are tormented by the baby crying at night, exhaustion, very painful. The baby can sleep quietly during the day, to the night is crying and restless, when crying, or crying regularly every night, or even overnight, which is medically called pediatric night crying, is a common sleep disorder in newborns and small infants. Parents who see their babies crying at night are often at their wits’ end, feeding, urinating, rubbing the abdomen, etc. are the common methods parents use to torture the exhausted; some elderly people in the family will think it is haunted, praying for half a day. In fact, there are many reasons why babies cry, and in general there are “physiological crying” and “pathological crying”. I. Physiological crying: Physiological crying, as the name suggests, is caused by the child’s physiological needs, the child cries to express the requirements or pain, such as hunger, panic, wet diapers, before defecation, clothing too cold or too hot, etc. can cause crying. At this time, if the child is fed with breast milk, soothed with intimacy, defecates, changes wet diapers, and adjusts the thickness of the blanket, the crying can stop quickly and is not pathological. If the child still cries, parents can open the baby’s clothes, pay attention to whether there are threads and other strangulation of the affected child’s fingers, toes and other conditions, there have been reports of strangulation of fingers and amputation, parents must pay attention. In addition, also pay attention to the clothes have no sharp foreign objects stinging the skin, or underwear caused by the possibility of itchy skin. Of course, there is a part of the baby day and night sleep reversal, or parents too spoiled children, a cry during the day to hold, do not want to let the child cry a cry, shaking, patting to let sleep, the result is more sleep during the day, the night will not sleep, crying and fussing. These bad habits can be corrected by parents. Pathological crying: Crying caused by disease is called pathological crying. The most common clinical diseases are the following, parents can rule out against: 1, rickets: infants, children, adolescents due to vitamin D deficiency in the body, causing disorders of calcium and phosphorus metabolism, caused by a systemic, chronic, nutritional disease characterized by bone lesions. The early manifestations are often due to calcium deficiency, resulting in over-excited nervous system, sleep disturbance, easy to wake up, easy to cry, often sweating. If you suspect calcium deficiency, you can check the bone alkaline phosphatase, calcium, etc., and combine with the child’s physical signs to confirm the diagnosis of rickets. 2, abdominal pain: acute intestinal inflammation, indigestion, intestinal parasites, etc. can produce abdominal pain and make the baby cry. The crying is paroxysmal and starts with the appearance of abdominal pain and stops when relieved. When crying, the baby is pale, has cold sweat, vomits, has diarrhea, refuses to press the abdomen, and cries when touched. It is important to check both sides of the genitalia and the umbilicus for hernias. Generally in this case, abdominal ultrasound needs to be checked. 3. Ear problems: If the baby has more secretions in the ear canal, causing itching and pain in the ear canal, crying will also occur. Fever and crying may also occur when the baby has acute otitis media. If otitis media cannot be excluded, you need to check the ear canal at the ear, nose and throat department. 4. Brain injury: Babies with headache and fever due to increased cranial pressure, urgent crying, screaming, high-pitched tone, short duration, fullness of the front chimney door, eyes dull, tonic neck, reluctance to lift and turn the head, stiff and inflexible limbs, and even convulsions should pay attention to brain diseases such as meningitis and intracranial hemorrhage. In addition, children recovering from cerebral palsy and encephalitis are also prone to restless sleep and crying at night. Crying caused by brain injury requires early examination and treatment, and generally requires first examination of cranial CT or cranial MRI. Children with brain injury are likely to develop epilepsy, so a long-range video EEG monitoring is necessary. In addition, things like some night terrors, nightmares, sleepwalking, talking dreams, and muscle or limb tremors during sleep also require EEG monitoring to exclude the possibility of epilepsy. If the baby is crying, parents must not be anxious and look carefully for the cause of the crying. If the crying is physiological, it can be removed by itself according to the situation; if the crying is suspected to be pathological, it needs to be seen in the hospital in time. If there is no direct cause for night crying, Chinese medicine can be used to treat it.
