<<rubber bottle nipple represents a mother's nipple
and we accept these as they stick out of diaper bags, are left lying around>>

I also have said the same things!  It is no coincidence that bottle nipples
are shaped the way they are <duh>- they are not square, triangular,
diamond-shaped, or rectangular for a REASON!  They are shaped like a human
nipple...the same human nipple that we are warned against showing in public
lest we offend!
