In the first 3 months of life, infants are characterized by short sleep time and frequent naps due to the small amount of food, many meals and short sleep cycles, and rarely sleep for more than 4 hours continuously, without much difference between day and night. 3-6 months old, infants enter a stable sleep period and can sleep for more than 5 hours continuously at night, waking up 1 to 2 times in the middle. However, there are some babies who always cry at night and make young parents exhausted. What are the reasons that make babies cry more than once? A. Teething pain Remind you to note that babies start teething from 5 months and grow all the way to 2.5 years old, babies will have crying and noise because of the discomfort brought by teething. Observe your baby’s cheeks and chin and consider if teething pain is bothering your baby if there is a visible red rash from drooling, swollen gums, tenderness and slight fever. Local cold compresses can be used to relieve the infant’s discomfort. When the baby’s teeth come in, sleep will naturally improve. Some infants, especially male infants, hold their urine, and the stimulation of a full bladder makes the infant feel uncomfortable, so the infant will behave as a restless sleeper, turning over and over, and crying. After urination, the baby will continue to sleep quietly. Do not give the baby too much milk or water half an hour before sleep, otherwise, the baby will urinate 3 to 4 times between half an hour and 2 hours after sleep. If you have mastered the time rule of baby’s urination, you can also take the initiative to change the baby’s diaper earlier at a certain time, so that you can effectively reduce the crying and noise caused by the baby’s urination. Nasal congestion in infants Experienced mothers will find that infants often have nasal congestion when they are breastfeeding, especially if they are newly born or have an unfortunate cold. A large nasal crust in the baby’s nose can block the nasal passages and force the baby to breathe through the mouth. This causes the dry air to irritate the throat and cause discomfort such as coughing, which can cause the infant to cry suddenly. You should learn to clean the nasal cavity with water dripping or using instruments to soften the nasal crust and remove the obstruction in the nasal cavity before the baby can suck smoothly and continue to sleep peacefully. IV. Pay attention to the temperature at night The indoor temperature should preferably not exceed 24℃. Being too hot or too cold, or wearing or covering too much, which makes the infant irritable or stirring off the blanket during sleep and subsequently feeling cold, can also lead to crying and quarreling. Fifth, the air in the irritant bedroom irritant, may make the infant’s respiratory tract allergies, obstruction, and therefore crying. Irritants can come from the smell of cigarettes, prickly heat powder, mosquito repellent lotion, paint, etc.. Noise When the baby is in a light sleep stage, or in the process of entering a light sleep from a deep sleep, any sudden, loud, unfamiliar sound can wake the baby and cause crying and fussing. Seven, colds Infants with colds are prone to wake up crying in the middle of the night. Because the cold can cause the infant’s respiratory tract obstruction and general discomfort, it should be treated symptomatically to shorten the course of the disease and reduce the symptoms as soon as possible. At this time, give the infant more hot water, drink fresh juice, and if necessary, under the guidance of the doctor, use drugs to reduce nasal congestion. Sleeping on the side is more suitable for infants with colds. VIII. Fever Infants will cry constantly when they have a fever. Parents should reasonably apply antipyretic methods or antipyretic agents under the guidance of a doctor to give the infant early relief and cooling care to avoid high fever convulsions. IX. Suffering from intestinal diseases During the hot summer and autumn seasons, infants often get restless and even cry at night when they eat foods that cause allergies or abdominal discomfort. At this time, pay attention to whether the infant’s abdomen will have flatulence, lumps, refusal to press, and stools. If so parents should immediately take the infant to the hospital for diagnosis and take medication under the guidance of the doctor.

For such infants, guardians need to pat, hug, and speak affectionately and quietly to soothe the infant, so that the infant can adapt to the new environment as soon as possible. If the person closest to the baby, especially the mother, is emotionally unstable, such as anger, frustration, insomnia, tension and anxiety, it is often easy to “infect” the baby; if there is a change in family relations, conflict between personnel or moving, the child will be in a state of emotional tension and will cry. If there is a change in family relations, conflict between people or a move, the child will be in a state of emotional stress and will cry. We hope that all caregivers will love and care for their babies and not “inoculate” their babies with adverse emotional changes that may affect their lifelong psychological development. Twelve, excessive activity The infant’s nervous system is not yet well developed, the inhibition function is weak. So if they are overly stimulated during the day or have too much intense activity at night before bedtime, the infant’s brain will still be in an excited state during sleep, thus triggering sudden crying during sleep, like a nightmare. Therefore, take care not to let the infant too much activity before bedtime, so that the brain excitement is too high, in order to ensure that the infant has a good sleep.
