My nephew actually ate soap until he was 2 1/2 years old. I started wondering why my soap bar was missing parts whenever he stayed at my place until i saw him bite off, chew and swallow quite a large portion.
I think cadence got it right with the perfumed soap. For me the worst would probably be some heavily scented shower gel. Yuck!I am aware no soap will taste good. I was wondering which one would be particularly bad, rather.
