There is a huge cultural divide on this one - in countries where it is not easy for parents to be constantly attentive to their children, diapers rule. Babies cannot control their bladders and bowels, so there would be nothing but a huge mess if they didn`t wear them. Right? I mean, babies just don`t have that sort of control...
But then you look at countries where the child is carried almost constantly and diapers are not available. Babies go on cue from their mother as early as a month after birth. A six month old who can`t control their bladder to go on cue has something wrong. It is only natural - all the babies can do it. Why on earth would someone put them in diapers and let them sit in their own waste?
A very good book to read on the differences in what is "normal" for small children and how culture skews it;

Japanese seriousness about the issue is a different matter altogether. That is a cultural issue and not a developmental one.
I want to touch back on this, as it has taken me all this time since reading it to assimilate what you are saying.

You've solved a long-standing unanswered question in my mind; 'What did mothers like the one in the above illustration do about the bodily waste of their infants before the invention of diapers?'
An entire facet of human history, missing from modern know-it-all American culture, explained by you in an instant.
The infants can control their bowels from a very early age, and do not foul themselves as presupposed by American culture and reinforced by diaper manufacturers.
This presupposes that the (non-American) mothers know how to train their infants to learn this behavior, which they do.
I must also differentiate between 'American mothers' and Native American mothers as shown in the next illustration, of a Native American mother and infant;

I wonder if the mother must accurately 'guess' when it is time for the infant to have a bowel movement, or is there some sort of expected 'line of communication' solicited by the mother and-or developed between her and her infant, to 'signal' when the child needs to have a bowel movement?
I've seen mothers' speak to 'cranky children' and say 'you need a nap'.
I wonder how the mothers who carry their children on their backs -where they can't even see them- may know when 'you need a bowel movement'.
