Spock! A classic. My parents, when raising me in the '80s and '90s, had a copy of his book and tried their best to follow what it said. I still recall the cover with the smiling baby. An amusing anecdote my father now has retold many times over (as fathers do) is that despite Spock's best advice there was something that I refused to do. His friend, a psychologist, pointed out that while Spock's advice might be good, my father could not expect me to behave as described because I had not read the book.

Another thing that's interesting here to me is the two fingers below the diaper to avoid sticking the infant with the pin. Two fingers under the diaper is still standard enough guidance that we and others we know received it at the hospital when diapering our child, though the reason expressed was one of tightness. I wonder if perhaps the former is the origin and the latter is a backformation.

And finally, the environmental question. Since my wife and I are quite old[0], and I want us to have more than one child I have pushed our household to the extreme end of consumerism[1]. We live in a 2 story flat in San Francisco, and until recently we had a changing station downstairs and two upstairs, with a diaper pail by each.

Here I encountered the problem that plagues anyone who has many battery-powered appliances - what convenience you gain in use, you lose when it comes to replace batteries. The Diaper Genie tall can we have is a very effective device at keeping smells in, but multiple cans means the time between replacement is doubled - something which you are rapidly made aware of by your senses[2], when it's time to replace the bag. The convenience is still worth it.

I do have a friend with more children than us, who will probably continue to have more children than us, whose family uses cloth diapers. So it is not an impossible task, and for someone adequately concerned about the environment and appropriately disciplined, perhaps quite straightforward to do.
