Do "fast-track" toilet training techniques really work?
Scientific studies suggest that they do. However, success requires a lot of preparation, and the techniques are not appropriate for some kids.
In this article, I describe how "fast-track" training is supposed
to work. I also review the scientific evidence for its effectiveness.
If you’re interested in other, more gradual, toilet training techniques, see this potty training guide.
Toilet training in less than a day
That’s the title of the book by Nathan H. Azrin and Richard M. Foxx,
two psychologists who first developed their method for children with
As far as I can tell, virtually all the “fast-track" approaches
to potty training (including the approach advocated by television's Dr.
Phil) are based on Azrin and Foxx’s ideas.
For this reason, let’s take a detailed look at their toilet training techniques.
- teaching through pretend play
- positive reinforcement (food rewards)
- practice drills, and
- overcorrecting for accidents.
Azrin and Foxx also emphasize the importance of timing. Not all kids
are ready for their approach. In their book, Azrin and Foxx specify that
kids should be 20 months or older, and they should meet several
developmental criteria. In particular, kids should be able to
- sit up by themselves
- stay dry for a couple of hours at a time
- recognize a full bladder
- point to body parts that you name
- retrieve objects for you, and
- follow simple instructions like “put the doll on the potty."
Kids should also be able to pull a pair of loose-fitting
underpants up and down by themselves. (For tips on how to help your
child learn these skills, see my article on
potty training preparation.)
There are medical and emotional criteria, too. Parents should also avoid
these toilet training techniques if children are ill, constipated, or
Last but not least, Azrin and Foxx warn that their toilet
training techniques require a lot of preparation. The title of their
book (“Toilet training in less than a day") is a bit misleading. To be
successful, a parent must do his homework.
So—as you read my brief summary below—-keep in mind that this is not
a substitute for reading their book. If you want to try fast-track
toilet training techniques, the Devil is in the details. Without
adequate preparation, you risk failure. And even worse—you risk making
your child resistant to other attempts at potty training.
Bottom line? No parent should attempt this method without first studying Azrin and Foxx’s book.
Azrin and Foxx’s toilet training techniques
When your child is ready, devote a day (4-6 continuous hours) to
training. You will need to set up a training area with a potty chair, a
doll with a removable diaper, food treats, and drinks. The room you use
should be large enough to play in, and relatively easy to clean up. The
authors suggest the kitchen. The authors also specify that you use a
doll can drink and “urinate" (pass water that has been poured in its
mouth). However, you can probably use an ordinary doll if you are
prepared to handle the special effects with sleight-of-hand.
Banish all distractions, including siblings and other family
members. Dress your child in loose-fitting training pants (and no other
layers of clothing) and encourage him to drink plenty of fluids
throughout the session. You want him to pee frequently.
Training consists of two phases. In the first phase, you use the
doll to demonstrate the potty routine. Give the doll a drink. Then tell
your child that the doll has to pee. Guide your child through the
process of removing the doll’s diaper, sitting the doll on the potty,
waiting for the doll to pee, and praising and rewarding the doll for
doing so. Continue with other aspects of the potty “script," like
emptying the doll’s “urine" from the potty chair and washing hands. Then
you check the doll’s diaper. If the diaper is dry, the doll gets
another reward. If it’s wet, you explain that big kids don’t wet their
“Overcorrect" for this mistake by guiding the doll through a
quick practice version of the potty routine. Encourage your child to
guide the doll himself.
Azrin and Foxx suggest that you repeat the doll demonstration
trials until your child understands the steps. This usually takes no
more than one hour (Azrin and Foxx 1974, p. 68). Then you start the
second phase of training—putting your child through the paces. What you
and your child did with the doll, you now do with your child.
The key to this potty training method is positive reinforcement
and overcorrection. When kids get it right, they are rewarded. When they
get it wrong (wet their pants) they perform practice drills.
Do these toilet training techniques work?
When Azrin and Foxx tested their method on 34 children, the
average child finished training in 3.9 hours and experienced a 97%
decrease in accidents the week after training. (Foxx and Azrin 1973).
Other studies have reported somewhat less spectacular outcomes, but the results are still good.
• One of the few randomized, controlled studies of toilet
training techniques compared Azrin and Foxx’s “toilet training in less
than a day" approach (TTLD) to an alternative potty training method
advocated by Dr. Benjamin Spock. The researcher found that TTLD was
significantly more effective. Kids were more successful and had fewer
accidents. In addition, parents rated TTLD as the more helpful potty
training method (Candelora 1977).
• Another study—one that did not randomly assign children to
treatment—tracked kids trained at home. The researcher reported a 74%
success rate for kids under 25 months. Among kids over 25 months, the
success rate was 93%. Eight weeks after training, kids averaged less
than one accident per day (Butler 1976).
• Another, much smaller study assigned children to be trained by
either by their own mothers or by an experienced trainer. Four of the 5
children trained by the practiced trainer were successful. Only 2 of the
5 kids trained by their own moms were successful. Because of the small
sample size, the results were not statistically significant (Matson and
Overall, these results suggest that Azrin and Foxx’s toilet training
techniques are pretty effective. Compared with other options, these
techniques are also associated with relatively quick results and an
earlier age of completion. For example, a recent study reports that kids
who were trained using another method
(the so-called “child-oriented approach"--reviewed here)
didn’t complete training until they were between 3 and 4 years old (Taubman et al 2003).
However, parents should keep in mind how little we know about the
relative effectiveness of different toilet training techniques. To
date, most studies of toilet training methods have focused on Azrin and
Foxx. We know less about the effectiveness of alternative toilet
training techniques. And very few studies meet the highest standards of
What we don't know
As of 2006, researchers at the University of Alberta Evidence-based
Practice Center were able to find only three randomized, controlled,
studies of toilet training methods (Klassen et al 2006). And only one of these studies (Candelora 1977) compared the effectiveness of two different methods—the “toilet training in less than a day" method v. the Dr. Spock method.
As the University of Alberta researchers note, more studies are
needed to determine if any one potty training method is better than the
rest. We also need more research to investigate
- how the individual characteristics of parents and children might affect potty training success, and
- whether or not there are any long-term, adverse side effects associated with particular toilet training techniques.
The first question may be crucial—especially for Azrin and Foxx
approach to toilet training. Check out the customer reviews on
Amazon.com, and you’ll see for yourself. This is a potty training method
that people either love or hate.
I suspect it depends on how closely parents follow Azrin and
Foxx’s toilet training techniques. If parents are unprepared or
uncomfortable with the approach, they are not likely to succeed. In the
study mentioned above, parents were less successful applying the
approach than was an experienced trainer. And—in another study—the
researcher found that older, more tolerant mothers were more likely to
succeed (Candelora 1977). Perhaps these parents were more confident and
relaxed during the training process.
It probably also depends on whether or not your child is
motivated and cooperative. Some parents have reported that their
children became upset during the training. If this happens, it’s best to
back off. Pushing an upset, uncooperative child can cause behavioral
problems. Azrin and Foxx are careful to note that parents must tailor
the toilet training techniques to the needs of their child. For some
families, this method may feel too regimented.
Other fast-track toilet training techniques
As noted above, other “quickie" approaches to training draw heavily on Azrin and Foxx’s toilet training techniques.
In Potty Train Your Child in Just One Day: Proven Secrets of the Potty Pro
(2006), Teri Crane outlines a three-step program that includes role
playing with a doll, practice runs with your child, and a “potty party."
Azrin and Foxx’s techniques also show up in Narmin Parpia’s Potty Training in One Day: A Guide for Today's Parents (2006).
This book is part of a system that includes a special potty, wetting doll, and training pants.
Are these methods any more or less successful than Azrin and
Foxx’s original formula? Unfortunately, we don’t know. Nobody has put
them to a scientific test.
What about the bare bottom?
Finally, for parents who dislike the regimentation associated with
most “fast-track" toilet training techniques, I should mention this
Let kids run around naked for a few hours, and wait for them to figure out for themselves when to use the potty.
Pediatrician Dr. Barton Schmidt recommends this approach for
children over 30 months who have already used the potty with parental
assistance (Schmidt 2004). If kids are slow to graduate from parent-led
practice-runs to full, toileting independence, the “bare bottom" method
might help them make that last breakthrough.
According to Schmidt, parents interested in this approach should
reserve at least one six-hour block of time (or a weekend) for training.
Some children might require several consecutive days. Remove all
distractions, strip your child below the waist and let her play. Offer
her lots of fluids to create many opportunities to pee. Keep her within
easy access of a potty chair at all times. This is easiest if you
confine your child to a room (or even better, a backyard if it’s warm
outside). Stay with your child, but do not ask her to sit on the potty.
Be cheerful, and let her work things out for herself.
If you are wondering what happens when your child has accidents,
the answer is that you get a mess. For this reason, you’ll want to stage
your training session in a place that is easy to clean. Clean accidents
without giving any lectures or lessons. Be upbeat and affectionate.
Although there are no scientific studies evaluating this
approach, Dr. Schmidt reports a high success rate in his own practice
(Schmidt 2004a). And similar claims have been made by psychologist John
