Whether it is normal for a 5-year-old girl to keep wetting the bed at night cannot be generalized, and its causes include physiological and pathological reasons. A 5-year-old girl is at the peak of growth and development, the urinary system and urinary center are not fully developed, and it is a normal physiological phenomenon that she is prone to bedwetting at night. Parents can train their children to develop the habit of urinating regularly, such as shouting at them to wake them up to urinate 2-3 hours during sleep, and after a period of time they can wake up to urinate on their own, so they will not wet the bed at night. Some little girls keep wetting the bed at night can be caused by pathological factors, such as spina bifida, urinary tract stones, urinary tract infection, etc., which can be clearly diagnosed through X-ray examination, urine examination, etc. For little girls who wet the bed at night, it is recommended not to drink water or drinks 2 hours before bedtime, and not to over-exercise, excitement, or exertion, which can avoid bedwetting to a certain extent.
