I don't know where all this psychotic clothes changing and washing comes from, but I believe it's related to germ/microbe phobia that's especially bad among mothers towards children. Maybe it's Johnson & Johnson's fault; they're continually bombarding moms with advertisements and commercials showing how laden their environment is with animated monster germs unless they liberally apply the latest anti-whatever miracle product.
It wasn't all that long ago when people took annual or semi-annual baths!!!
And that is why perfume was invented.
The happy medium is somewhere between.
