Boys usually are dry by night by the age of 6 yrs, while girls are faster and achieve night control by 5 yrs age. So, after these ages, it is a matter of concern if your child is not dry in night. It is of even more concern if the child had started remaining dry in night for more than a year and now again is bed wetting in night. Worms in tummy are very unlikely to result in bed wetting and there are other more common causes like excess water intake, constipation, urine infection, excess TV watching or video games.
So, First of all, one has to identify these causes and remove them or treat them. If still child continues bed wetting then we have to do bladder training for 4-6 months Lastly, if everything fails, then special medications are given to get the results. It is important to note that these special medications will be of no help if other factors as mentioned above are not taken care of and bladder training has not been attempted religiously for 4-6 months
