Common causes of restless sleep: the quality of sleep has a great influence on the baby's health. If the baby doesn't sleep well, it's as if he is not sleeping. The possible reasons are as follows: 1. Improper diet: overeating before going to bed, frequent feeding at night, inadaptability of newly added complementary food, indigestion, etc. 2, physiological reasons: teething period, weaning period, after vaccination. 4, sleep problems: long-term lack of sleep, unreasonable or irregular sleep diet and defecation schedule lead to sleep disorders; Changing sleep time at will, parents lack the consciousness of cultivating and establishing their children's sleep biological clock. 5, sleeping environment: such as dirty air, room temperature is too high or too low, too dry; Bedding is too thick, sleeping in cotton-padded clothes, etc. 6, diseases: constipation, diarrhea, eczema, infectious diseases such as otitis media, sinusitis, early rickets, pinworm infection; Children are unwell, such as fever, stuffy nose, abdominal distension, pain, diarrhea, constipation, vomiting, itching and other symptoms. 7. Changes in daily life: for example, going out, moving to a strange new house, having a new nanny or relative to take care of the baby, and worrying about the separation of parents on business trips. There are many reasons, which can be divided into two categories: first, external factors 1, hunger is more common in newborns and infants within three months. At this time, it is necessary to breastfeed or nurse. Older babies can rule out this factor if they are full before going to bed. When the weather is dry, the baby may be thirsty at night. Adding some water to him can calm him down. 2, calcium deficiency calcium deficiency is one of the primary factors leading to baby's unstable sleep, and most MM will consider it. Calcium deficiency and decreased blood calcium cause the excitability of autonomic nerves in the brain to increase, leading to night waking, night terrors, restless nights and restless sleep. The solution is to give your baby calcium and vitamin D and get more sunshine. A. Calcium supplement: 300-500mg of B element calcium per day, and VD supplement: 400-800IU3 per day, which is too hot. Nowadays, most babies wear coats that are too hot. In fact, it doesn't matter whether the baby is cool or not. Being too hot will make him uncomfortable and easy to get sick. If the room temperature is quite high, wear a sleeping bag and cover with a small quilt, the baby will feel hot and wake up. At this time, it can be solved by reducing coverage. 5, wet urine because diapers are too wet or too tight, it will also make the baby uncomfortable. Some babies don't want to pee on diapers easily when they want to pee, and they also toss and turn. Careful MM observation. 6. The baby is too excited during the day or has a slight change in the environment, which can also be related to excessive excitement or tension during the day and changes in daily life. For example, going out, changing sleep patterns, moving to a new home, a new nanny, and strangers coming. For example, the departure of the old nanny will make the baby unable to sleep at night. Frequent change of caregivers will also significantly increase the incidence of sleep disorders in children. Sleeping too much during the day will also affect your sleep at night. 7, teething or unwell baby often has restless sleep during teething. Sometimes, after several nights of tossing and turning, the mother finds that the baby's gums have white teeth. It can be seen that there is still some pain in teething. Of course, other diseases can also cause restless sleep. The night before illness or fever, I often fidget. All these require careful observation and judgment. Second, the internal factors The internal factors of children also have an impact on sleep: the development of brain nerves is not yet mature. The child has not established a fixed schedule physically. The adjustment of baby's circadian clock depends on the cooperation of baby's physiological maturity. According to the survey, babies with high excitability of nervous system tend to have late physiological maturity and are prone to sleep disturbances. This kind of baby may be more active, extroverted and sensitive than a baby who sleeps well. People's sleep is divided into deep sleep and shallow sleep, which alternate for about 3-4 hours at night. Babies, like young children, may alternate between deep sleep and shallow sleep for a shorter time, about 2-3 hours. Adults and many babies who sleep all night can better adjust themselves and go back to deep sleep when a light sleep comes. And many babies and even many adults can't adjust themselves to sleep, so they wake up from a shallow sleep. After excluding external factors such as thirst, hunger, cold and heat, calcium deficiency, abdominal distension and teething excitement, your baby who can't sleep well may not be able to adjust himself to enter a deep sleep state just because of the active cerebral cortex. Why do you expect your baby to be someone you can adjust? These phenomena will always be solved after weaning, or as the baby grows up.
