Answer: 

In 1977 my daughter was born with a serious skin condition known as seborrhea. By the time she was 3 months old, her little body was covered in angry red patches that burned and itched. She could not be held. Her clothes irritated her. Commercial soap and detergents seemed to aggravate Sara's skin. Prescription creams and lotions did nothing to soothe her.

An elderly neighbor named Dorothy suggested I should try her old-fashioned laundry soap. I washed all of Sara's clothes and bathed her little body with and old brown bar of Dorothy's homemade soap. In a week my little girls skin was normal! So I learned to make my own soap.
