If your child is around 5 or 6 years of age and still wetting at night, bedwetting alarms aim to help your child wake when recognising the sensation to urinate.
An alarm teaches your child's brain to respond to a full bladder, even during sleep.
When exposed to wetness (urine) the alarm makes a loud noise to wake your child. The sound needs to be loud enough and quick enough to wake your child prior to complete bladder emptying.
When beginning your child will wet and the alarm will sound. Your child (and you) will wake up and you will need to take him to the toilet to completely empty his bladder of any “left over” urine.
Initially your child is likely to empty his bladder before reaching the toilet, but with practice this should improve.
Using the alarm every night and waking up just after wetting should eventually teach your child's brain to wake up prior to wetting. With time, wetting will happen less frequently and eventually your child will stop wetting altogether.
Once your child establishes a consistent pattern of waking during the night prior to wetting then you will no longer need the alarm.
Some children stop wetting within days or weeks, other children and can 2-3 months to stop wetting.
