The musical diaper alarm
Considering all the claims and hype, there haven’t been many good experimental tests of
potty training techniques.
But Alexandra Vermandel and her colleagues are trying to change that.
They’ve wondered if they could speed up potty training by using a diaper
alarm--a device that responds to moisture by playing music.
idea is to alert caregivers immediately when a diaper is wetted and to
make kids more aware of urination. As soon as the alarm goes off, kids
can be encouraged to go to the bathroom. This will help children learn
to associate the sensations of a full bladder with the toileting
Vermandel and colleagues have tested the alarm in two settings, at home and in daycare.
In the home-based study, researchers randomly assigned kids, aged 20 to 36 months, to receive either
- diaper alarm-based training, or
- timed potty training (putting the child on the potty at regularly-timed intervals)
rated the children’s toileting behavior at several points in
time--before training began, two weeks after training ended, and one
The children in the diaper alarm group showed significantly better progress (Vermandel et al 2008).
The daycare-based study yielded similar outcomes.
three weeks, kids in daycare, aged 18 to 30 months, were given either a
diaper alarm or a placebo (non-functioning) alarm. As in the home-based
study, researchers evaluated toilet training skills before and after
Kids were considered to have completed toilet training
when they wore underpants, showed awareness of their need to urinate,
initiated visits to the bathroom, and had no more than one accident per
After three weeks, the kids who'd used diaper alarms were
significantly more likely to have completed training. Almost 51.9% of
the alarm group met the criteria for being potty trained. By contrast,
only 8.3% of the control group did (Vermandel et al 2009).
Does this mean that you should get your toddler a musical diaper? Not necessarily.
haven’t been able to read the details of the home-based study, but from
the abstract I gather that the effects were modest. And remember--the
home-based study pitted the alarm against another potty training method.
By contrast, the daycare-based study compared the wetting alarm with a
placebo (a device fitted in the diaper that didn’t make an alarm). So it’s not surprising if diaper alarms seemed more effective in the daycare study.
some parents might really like a "smart" diaper. Many potty training
techniques depend on the caregiver’s continual vigilance. An alarm might
give caregivers more flexibility. And it’s easy to imagine that diaper
alarms would be especially helpful in group care settings, where
caregivers must divide their attention amongst several kids.
