Most toddlers do not become fully toilet trained until they are between 2 and 4 years of age. Some will be able to stay dry during the all day and night, while others may have problems with nighttime bed-wetting, or enuresis.
Bedwetting is normal and very common among toddlers. Unfortunately, the cause(s) of bedwetting is still unknown. In most cases, the toddler's bladder is probably not yet developed enough to hold urine for a full night. Or, the toddler may not yet able to recognize when his bladder is full, wake up, and use the toilet. Sometimes, the cause may be genetic. Bedwetting tends to run in families.
During the last stages of toilet training and beyond, bedwetting can be an enormous frustration for toddlers and their parents. But here is some information that can help.
Strategies to Avoid Bedwetting Blues
Parents may help toddlers who wet the bed by using these strategies:
- Limiting liquids before bedtime
- Encouraging the child to go to the bathroom before bedtime
- Praising the child on dry mornings
- Avoiding punishments
- Waking the toddler during the night to empty their bladder
While you're trying some of these strategies, make sure your toddler's mattress is adequately protected by a good cover.

You could also encourage your toddler the wear training pants during the night to avoid accidents.

If none of these strategies produce dry nights, parents should consult their toddler's pediatrician. One of the approaches that many pediatricians recommend is using a bedwetting alarm.

Bed-wetting alarms are considered a safe and effective way to stop bedwetting. The alarms have a simple moisture-sensor that snaps into your toddler's pajamas. A small speaker attaches up on the shoulder with Velcro.
At the first drop of urine, a piercing alarm goes off, that sounds similar to a smoke alarm. Instantly, the toddler reflexively stops urinating. Now he is awake enough to go to the bathroom on his own. By using this alarm, the toddler may be able to wake up on his own and after awhile even sleep through the night and stay dry.
One important thing to remember is never punish a toddler for wetting the bed. This will not solve the problem. Your toddler doesn't wet the bed on purpose. He or she needs your love and support. You may feel frustrated at times, but your toddler may be too.
