Bedwetting is a common problem in children and could last upto 5 years of age in about 25% of children. I understand that it is awkward but I do not think that you need to be proactive and get so many tests done. You have to gradually train the child so that bedwetting gets demotivated. Things that you could do are: * Shift times for drinking. Increase fluid intake earlier in the day and reduce it later in the day. * Schedule bathroom breaks. Get your child on a regular urination schedule (every two to three hours) and right before bedtime. * Be encouraging. Make your child feel good about progress by consistently rewarding successes. * Eliminate bladder irritants. At night, start by eliminating caffeine and if this does not work, cut citrus juices, artificial flavorings, dyes (especially red) and sweeteners. * Avoid thirst overload. * Consider if constipation is a factor. Because the rectum is right behind the bladder, difficulties with constipation can present themselves as a bladder problem, especially at night. * Do not wake your child up to urinate. Randomly waking up a child at night and asking her to urinate on demand is not the answer, either – and will only lead to more sleeplessness and frustration. * You may use a bedwetting alarm that beeps when you it feels moisture develop inside the piece of clothing the device is attached to. * Do not resort to punishment. Getting angry at your child does not help her learn. The process does not need to involve conflict. * The best non medical intervention is perhaps star charting. Award a star to your child for each dry night. Promise a small gift in case she gets a certain number of stars. Delayed gratification increases the effectivity of the method. Hope that helps. I would suggest that you get a second opinion.
