Reason 1: improper care mainly occurs in 6 months -4 years old children, before bedtime family members have to hold the child to hold pat, shake, walk around or rubber nipple (including nipple) habit. These activities accompanying sleep has been continued until the child is fully asleep to gently put to bed, over time to develop habits. Nighttime pediatric sleep a cycle of waking up is a normal phenomenon. Generally a little activity and sleep, parents do not even notice. But some children still wake up and ask to hold, pat, shake or contain nipple to fall asleep, do not meet his requirements on the crying and screaming. This is because the child cannot fall asleep on his own without the accompanying activities that he is accustomed to. In order to correct the bad habits of infants and toddlers to ask for holding, patting, shaking and so on before bedtime, the first night of sleep, let the child lie down on the cot to sleep, if the child began to cry, let him cry for a period of time, at least 1-2 minutes, can be given to comfort, but do not hold up, until he quieted down, parents can leave. If the child cries again, wait longer (2-5 minutes) and comfort him again. This can be repeated several times, this process can last several hours, parents are encouraged to adhere to this, the second night of sleep the same practice, but the child crying waiting time is extended. The first time is 2-4 minutes after giving comfort, the second time 5-10 minutes, and later more extended. In doing so, parents should not be angry or lack of confidence, insist on doing it. The 3rd night can be effective. The child changes from a loud cry to a small cry, and later stops crying and falls asleep on his own. Wake up at night time becomes shorter, after waking up, do not cry, and go back to sleep by themselves. This method is not suitable for small-month-old babies. Reason 2: Excessive fluid and food intake Healthy babies can sleep through the night by 6 months of age and do not need to eat at night. If the child wakes up at night, because he is hungry, thirsty, to feed the milk and water, get into the habit, the child will be hungry at night, must eat, in order to fall asleep again. Into the amount of liquid more, inevitably more urine, urination can also make the child wake up. If this is more often, disrupting the normal day-night rhythm and sleep cycle of infants and young children, can also affect their body temperature, digestion and endocrine secretion of the circadian rhythm, is not conducive to the normal growth and development of children. Handling method For those who eat or drink too much water at night, eat more before the child goes to bed, such as milk with some rice flour food, so that the milk becomes thicker. Drink as little water as possible before bedtime. After waking up at night, the amount of milk eaten is gradually reduced, and the milk is gradually thinned with water. And gradually extend the feeding interval until completely stop night feeding. As the amount of nighttime intake is reduced, the amount of urination will be reduced, which can steadily extend the duration of sleep. Reason 3: environmental factors from infants and young children should have a reasonable work and rest system and a fixed sleep environment. The prescribed time to get up, daytime naps, eating and going to bed at night, should be strictly enforced. Children are best to sleep alone in the cot (some countries have their own bedroom), the pillow of the bed, was and accompanied by small toys as much as possible fixed. When the child has the desire to sleep when they lie down, before going to sleep parents say goodbye or kiss the little face and leave, to develop a good habit of the child to fall asleep by themselves. If the child can not insist, to leave the crib, deliberately find reasons such as drinking water, watching TV, play, etc. should be given to stop. If parents give in, his demand will gradually escalate, it is impossible to develop a regular sleep habits. In addition, the sleep environment noise interference, such as home radio, television, or near the sound produced can prevent children from sleeping. Treatment The improvement of the sleep environment is easy to understand. However, there will be practical difficulties in solving them, especially the limitations of living conditions. Parents should create as many conditions as possible according to local conditions, so that children have a fixed and appropriate sleep environment. Cause 4: Allergy Human milk protein allergy can cause severe sleep disorders in infants and young children. Cow’s milk allergy is often difficult to distinguish clinically from colic because it begins at the same age and is accompanied by hypersomnia, irritability, and intermittent nighttime distress. Typical presentation is waking up at night (5-6 times per night) and a shortened total sleep time. There is also frequent daytime distress. Physical examination is unremarkable; it is possible that some infants have anemia or blood in the stool. Polysomnographic analysis shows sleep disturbances. Diagnosis may be based on clinical signs and allergy tests. Allergy tests often show increased IgE levels and a positive Radio allergosorbent test (RAST) for milk proteins. Management A history of dairy allergy, once diagnosed, resolves the sleep disorder within a few weeks with a hydrolyzed milk protein milk formula. This allergy usually resolves spontaneously in 2-4 hours. Other causes such as otitis media and neurological disorders can also cause sleep disorders.
