Children with poor sleep should first of all exclude the reasons of insufficient feeding and not eating enough. Too much activity or eating too much before going to bed at night may make them sleep unsteadily, and they need to change their routine, listen to relaxing and soothing music or listen to their mothers tell stories before going to bed, do not get overexcited, laugh excessively or watch more exciting TV shows, and gradually ease their bedtime excitement. Some children, even without the above conditions, may have restless sleep, easily startled, and may wake up at the slightest sound. Most of these children may have low calcium, so they should pay attention to vitamin D supplementation, drink milk, eat eggs, and get more sunlight, and if the child also has excessive sweating and loss of appetite, they can go to the hospital for microelements testing and adjust the treatment accordingly. In addition, such as nasal diseases, adenoid hypertrophy, allergic rhinitis, etc. can also appear sleep disturbance, if poor sleep persistently can not be relieved, it is recommended to go to the hospital to seek professional medical examination and treatment.
