#1 Every time, P&G create a new 'Pampers' line, the 'green group' create the standard list of complaints. For years, they complain that the SAP within disposable diapers create rashes AND absorb vital moisture from a babies skin. Every time, under medical testing, the validity of that statement fails. In reality, due to the absorbency capability of Pampers products, some parents leave their child in a diaper much longer between changes than they would, or could with a cloth or standard disposable diaper. As a result, the infant is sitting in stale faeces and urine, which has time to break down the childs skin. To some, the mentality is that P&G is responsible for the rash and associated problems rather than the negligent parent. (see McDonalds coffee as an example) If parents paid attention to their infants needs, diapers wouldn't be needed. (see infant potty training).
I have tested the pampers 'dry max' technology (using a baby diaper as an insert) and found that the pampers absorbs upto 10 times that of an adult diaper. To test this yourself, place the dry diaper on an accurate scales, and zero the scales. Using warm salt water, ( a large sink would be ideal), submerge the diaper into the water, and leave for 15mins. Weigh the diaper again on said zeroed scales. Compare this weight ( the water weight the diaper has absorbed in 15 mins to that of another diaper.
#2 P&G seem to always use Kimberly Clarke's research team to outlay the original cost for market test before copying the design. P&G seem to think / know from market sales of Huggies 'Jeans' diaper, that enough market demand - one viable enough to cover the cost to produce multiple designs of diapers.
What I want to know is, is the law, OR people's attidudes changing in relating to see an infant in only a diaper / diaper & t-shirt. A few years ago, it was not proper (or legal in some states / countries) to dress a child in only a diaper / diaper and t-shirt, the diaper would be covered by either shorts / or some form of undergarment - like a onesie etc.
