Charlie... have you ever seen a 6mos old interested in potty training? If so, I'd love to meet the child.
Seriously, though. I don't agree with babying your children, or keeping them in diapers when it's not necessary. We are already starting on my sister, and shes about 19 months now. However she walks, talks, knows what it is... etc. She is starting to become 'ready.' However - I have NEVER seen a 6 month old, or 3 month old, that is -ready-.
Well they don't have to be interested in it, it just seems from the link that parents are simply training their infants and succeeding at doing it!
My beef with the whole thing is this quote: "For many parents in the United States, the idea of potty training before a baby is able to walk, or even before age 2, is not just horrifying but reprehensible - a sure nightmare for parents and baby, not to mention a direct route from the crib to the psychiatrist's couch."
This must be a weird cultural thing. I see nothing wrong with exploiting the fact that infants make signals before they 'go', and these signals can be used by the parent. It's more like the parents are the ones getting trained.
And, assuming the article isn't lying, clearly some infants can be properly potty trained. It's just like training a cat or a dog. I find it highly unlikely that early potty training could result in psychological damage, unless the method of training was highly stressful.
I really think that this is a cultural thing where making children grow up faster than what is expected is frowned upon. I think there's nothing wrong with it, if it can be done, without any problems, then it should be.
