Oopsie Heroes
Can Oopsie Heroes be used in combination with a diaper?
Good question! But no, we advise you not to use Oopsie Heroes in combination with a diaper. Here is why: when you place the sensor on the outside of a diaper it can’t detect the urine, placing it on the inside would block the sensor signal. Next to that, experts advise people to not use diapers anymore as soon as you start using a bedwetting alarm. The learning curve of the child will be much less since the diaper makes the child feel too protected and he or she won't notice when the diaper gets wet. So it’s better not to use diapers.
Does the sensor use Bluetooth?
Nope, no Bluetooth signals. We use sound to communicate with the mobile device. How cool is that?!
Where do I need to place the sensor?
Using the stickers provided, place the sensor on the outside of the undergarment or pyjama trousers, in the area where a leakage is expected.
Does the sensor work under a blanket?
Yep! Depending on the thickness of the blanket the sound volume will be high or low. A thicker blanket = a lower volume. The sensor has a reach of about 3 meters.
How can I clean the sensor?
You can use a wet tissue to clean the sensor. Please don’t put it under water.
Where do I place the mobile device at night?
We advise to place the mobile device in your child's bedroom within a 2-3 meter distance from the bed.
How does the calendar in the Oopsie Heroes app work?
Why does the app say my child wet the bed the next day?We know this can be a bit confusing at first. Let's say your child had an accident at 11:00 PM on the 25th. You wake up the next morning (the 26th) and expect to see the event logged as happening on the 25th — but the app shows it on the 26th instead.
💡 Here's why:
The Oopsie Heroes app uses a special 24-hour window from 6:00 PM to 6:00 PM to track progress. This design helps group each full night of sleep into one easy-to-understand "episode," rather than splitting it across two calendar days.
So if something happens overnight — whether your child stays dry or has a wetting incident — the app logs it to the nextcalendar day. That way, you can clearly see how each full night went, rather than tracking fragmented bedtime and morning events.
It's not a bug — just a unique way the app helps you focus on nightly patterns of progress.
Here's how to check the full story:
If you're ever unsure, just tap and hold on the calendar date in the app. It will show:
🌟 A star for any dry spell (like a second sleep after an accident),
💧 A drop for any wet episode.
This gives you a clearer picture of what happened throughout that tracking period.
Can I close/lock the mobile device during the night?
Yes, you can lock the screen once you have activated the sleep-mode of the app.
Bedwetting alarms in general
How to bedwetting alarms work in general?
When our bladder is full, it sends a signal to our brains, informing us that it's time to visit the toilet. For some children, this communication is not yet developed enough to wake them up during the night. Therefore they need a helping hand.
A bedwetting alarm like Oopsie Heroes can be the perfect solution for this. Bedwetting alarms wake up the child just after an "Oopsie moment", when the signals of the bladder are the strongest. When you do this after every nighttime accident, the brains of the child will be trained to recognise the signals of the bladder. This will eventually help them to wake up on their own and visit the toilet before wetting the bed. Bye bye Oopsie moments!
How often does bedwetting occur?
About 15% of the 6-year-olds and 5% of the 10-year-old children still wet the bed during the night. Even about 1% of the adults still have these "Oopsie moments" now and then.
It is twice more common with boys then with girls and when both of the parents had bedwetting issues when they were young, there is an 80% chance their children will have the same issues.
So you're not on your own, there are quite a few children who are coping with bedwetting issues.
What is the success rate of bedwetting alarms?
According to different studies, bedwetting alarms have a success rate of 75-90%!Source: Doleys, D. M. (1977). Behavioral treatments for nocturnal enuresis in children: a review of the recent literature. Psychological Bulletin, 84(1), 30.
From what age can I start using a bedwetting alarm?
Experts advise to start using a bedwetting alarm from the age of 6 years old.Only after this age the child has developed enough to be able to be "trained" for nocturnal enuresis (bedwetting) issues.
Next to that, bedwetting alarms are often only reimbursed by health insurers when your child is 6 years or older.
