According to the Mayo Clinic, bed-wetting can be minimized by reallocating the majority of liquid consumption to day time hours. It suggests eight ounces of liquid as a sufficient quantity but advises to get a doctor's opinion given the specific individual needs of children. Additionally, because caffeine increases the urge to urinate, the consumption of this item should be limited to daytime hours. KidsHealth.org advises to avoid caffeinated beverages completely.
Bed-wetting is a symptom of a child's developing control over his bladder and a normal part of toilet-training, as states the Mayo Clinic. Most children grow out of it by age seven.
The Mayo Clinic further suggests the child "double voids" prior to bed. This is the act of urinating in close succession, first at the beginning of an established bedtime routine and then a second time just before laying down to sleep. Moisture alarms which detect the presence of liquid on the child's clothing or bed linen are slow for results but have long-lasting effects. Medicine that slows the night-time production of urine, reduces bladder contractions and increases bladder size or changes the child's sleep cycle can be used in more extreme cases. Side-effects of these medications, however, can be serious to fatal.
