Yes, this has become "oh the rage" in ALOT of places, countries. For example: a lady at my church adopted 2 little (and I know I won't spell this correctly) Khazikstan babies (who are now almost 4). She got them when they were 8 months old. Starting at 5 or 6 months over there they PT their kids. Due to the fact that they are all in a orphanage and only have cloth diapers, they run out quickly (very poor country). So, they have (this lady told me) little potty chairs all lined up on one wall. They will place a certain amount of babies on these chairs and just leave them there for about 1/2 hour so that they can eliminate that way they save on washing diapers!! The lady told me that she didn't keep up with it at home, she didn't think that they truly understood, it was just done after eating. I think that PT is meant for toddlers who know what they are doing. They have to exhibit all kinds of readiness signals before they will PT, and they have to WANT to do it. Babies have no clue what they are doing, it is US that use their signals to put them on the pot. It is a very interesting concept indeed. But, not for me or my kids. I actually enjoy changing diapers. It is just one more way I get to be a mom! LOL!
