What child has never wet the bed? But when is bedwetting abnormal? Generally, from birth to 2 years old, the child’s urination cannot be controlled at will, and after the age of 2, the ability to control urination gradually increases, and by the age of 3, the child is able to control urination very well. However, if the child occasionally wets the bed because of increased drinking and excessive fatigue and deep sleep, it is not normal when the child wets the bed every week or every day, and if the child is 5 years old and still wets the bed more than twice a week, it is considered enuresis. There is also a situation where the child has not wet for more than six months and then bedwetting occurs, it must be an abnormal phenomenon.
