As we all know, the sleep of children is very important for their growth and development, and the sleep of children is affected by many factors, mainly including intrinsic and extrinsic factors. First, the intrinsic factors include whether the child is ill (such as fever, diarrhea, abdominal pain, asthma, skin allergies, etc.), the child’s own temperament characteristics, poor sleep habits, etc. Second: extrinsic factors include sleep environment and nurturing environment: crowded living environment, loud noise, too much light, too much cover, too hot, or too cold during sleep will affect the child’s sleep, especially the temperature of the sleep environment changes too much, will significantly interfere with the child’s sleep, the best sleep environment temperature is 22-27 degrees Celsius. Sleeping in the same bed as the parents can also significantly affect the child’s sleep, especially in breastfed children, whose nighttime sleep patterns may be intermittent and discontinuous, so it is best for the child to sleep in a separate bed from the parents. Poor parental response can also affect the child’s sleep, for example, if the child moves or cries and the parent immediately picks up, feeds or defecates the child, this can also affect the child’s sleep. The family’s economic status, cultural background, parents’ education level, parental harmony, whether the mother is separated from the child, and whether the parents’ life is regular will all affect the child’s sleep. To cultivate good sleep habits, we should pay attention to the following points: the sleep environment should be quiet and relatively dark; it is better to fix the time of going to sleep and getting up, and strengthen the training of the physiological rhythm cycle; the room temperature is appropriate, not too cold or too hot; avoid hunger when going to sleep, and do not drink too much water before going to bed; develop the habit of falling asleep by yourself, and do not have the bad habit of hugging, patting, shaking, or containing the nipple before going to bed; avoid playing too much 1-2 hours before going to bed. Excited; before going to bed can take a warm bath, massage to promote sleep; daytime naps should be appropriate, avoid long or frequent naps during the day.
