There is no English term to suitably describe "infant potty training" (IPT) as a whole, since (a) an infant cannot sit on a potty and (b) the process is more akin to teamwork (with your baby) and interconnectedness than actual training. Communication is the key to connecting with your baby about elimination.

Perhaps the most unique characteristic of this method is that parents typically begin working with a baby before she can even sit. Instead of beginning research on toilet training around the time a child takes her first steps, parents need to consider this method during pregnancy or the first weeks/months after delivery.

Philosophy
Babies are smarter than we think! The big mistake that people make is to presume that a newborn baby is unaware of going to the toilet. An infant is helpless in so many ways that it is hard for Westerners to imagine such a tiny being could be aware of peeing and pooping. It is even harder for us to believe that an infant has some control over elimination. With these preconceived and narrow views, we encourage and teach our babies to be unconcerned about wetting and soiling diapers. In short, we teach our infants to use diapers as a toilet.
A normal, healthy infant is indeed aware of the bodily function of elimination and can learn to respond to it from infancy. By using diapers, we condition and thereby train baby to go in them. Later the child must unlearn this training.

What Does It Take To Do This?
Time, diligence and patience.

When Do I Start?
The ideal time to start is anytime from birth to 4 months old. During this time, there is a window of learning open.

How Long Does It Take?
The average age of completion in the West is around 2 years, although babies have fairly good control of elimination for *many* months before completion.

Is It Safe?
Of course, as long as parents have the right mind set. Parents must be relaxed and positive about working with their babies. This is a non-punitive method!

Does It Really Work?
Yes, but not without some effort. Success does not just happen on its own. It takes at least one committed adult and several months of perseverance to complete infant potty training.

Does My Baby Have To Be Naked?
This is not a requirement. Many parents keep a diaper or training pants on their baby in between potty visits, while others prefer to leave their baby bare-bottomed or naked most of the time.

A Wonderful Discovery (My Experience with IPT)
When my third son was born, I dreaded the thought of another bout of conventional toilet training which would entail years of diapers. I asked a lady from India for advice, and she taught me this amazing and loving technique, which is the mainstream method used throughout much of Asia and Africa. From the day I started working with my 3-month-old son, he rarely needed a diaper, day or night. He stayed dry during most of the day at age 18 months and was finished with all aspects of potty training at age 25 months.

Outlook and Source
This method begins with conditioning and can be approached in a rational and scientific manner as well as an intuitive and spiritual one, or a combination of both depending on what works best for you and your baby. The rational approach involves timing and observation of elimination patterns and baby body language. The more spiritual approach involves intuition and "tuning in" to your baby in more subtle ways.
