With reference to terminology, I just wanted to mention that there are many terms that refer to infant pottying, and all of them have their pros and cons. See list at end of message.

Here are links for further info:

http://www.TimL.com/ipt Infant Potty Training Fundamentals translated into many languages

http://aitt.evassist.it International Board for the Study, Research and Promotion of Assisted Infant Toilet Training — includes a list of medical journal articles, supportive pediatricians and more

These terms all refer to the same method of toilet learning, so take your pick at what you prefer to call it:

infant potty training (IPT; also a book title)
infant pottying
infant toilet training
elimination communication (EC)
diaper-free method
natural infant hygiene (NIH)
trickle treat (also a book title)
