Neonatal crying is divided into pathological and non-pathological. Non-pathological crying can include “cold, hot, hungry, urine, stool, sleepy, afraid” and so on. Pathological crying refers to abnormal crying, such as infection, pain, etc. Response to cold: low cry, weakness, skin appears or cyanosis, in severe cases pale and dry, whole body curled up, movement reduced. At this time, the mother can hold the baby in her arms or cover with a small quilt. Reaction to heat: loud and powerful cry, flushed skin, light sweating on the forehead and face, limb activity, and mild fever in severe cases. At this time, the mother needs to loosen or remove the small quilt, and those who sweat a lot need to wipe sweat and change clothes. Response to hunger or thirst: At this time, the cry is loud, high-pitched, and regular, while the head turns from side to side. At this time, the mother can touch the baby’s lips tentatively, and if the baby immediately takes the nipple and sucks it up, then feed the baby, and the child will not cry again when he or she is full. Reaction to wetting or defecation: Cries often appear suddenly, sometimes urgently, and the activity of the lower limbs is more than that of the upper limbs. Sometimes there is a reddish face and forcefulness before relieving the stool. At this time, you can change the diaper, and pay attention to the cleaning and emolliency of the small buttocks to prevent the occurrence of diaper dermatitis. Reaction to sleepiness: If the baby is tired, but not easy to sleep, there will be crying, crying loudly, hands rubbing the face, especially the nose and eyes, at this time, the mother patted the baby, pay attention to the rhythm of patting, and with the baby crying sometimes, getting lighter and lighter, the rhythm of patting is getting slower and slower, until the baby falls asleep. Reaction to fear: Reaction to sudden sound or position change or other external stimuli, first appearing frightened performance, such as arms raised, hug-like or shivering, etc., crying immediately afterwards, crying, urgent, facial reddening, at this time, if the mother gives soft comfort pat coaxing, crying noise can disappear more quickly. In addition to nasal congestion when the baby eats milk, we also need to pay attention to whether there is too little breastmilk or the pacifier opening is too small, at this time, we can see the baby sucking a few mouthfuls before swallowing, a few minutes later there is crying and noise, cry a few times and then eat, repeatedly. In this case, the mother and father can add formula after breastfeeding, or open the pacifier appropriately, so that the milk flows smoothly after squeezing; when there is too much breast milk or the pacifier opening is too large, the baby will also cry and quarrel, at this time, the baby swallows immediately after each sucking, and occasionally chokes and coughs. Other non-pathological crying can also be seen before defecation, tummy distension, tight clothes, mosquito bites, foreign objects caught in clothing (such as fine threads, small thorns, needles, etc.), discomfort in body position, etc. Mothers can carefully observe and adjust in time. Pathological crying is mostly persistent and violent. Any infection can cause discomfort in newborns, thus causing crying and fussing, such as stomatitis, otitis media, pneumonia, sepsis, peritonitis, abdominal pain, enteritis, and urinary tract infections.
