don't suck on your baby's binky and share it with them - else they'll get thrush... and die.

(ok, i'm being wildly sarcastic, thrush won't actually kill anyone)

a little more information on thrush (aka Candidiasis) from wikipedia.org:

Candida yeasts are usually present in most people, but uncontrolled multiplication resulting in disease symptoms is kept in check by other naturally occurring microorganisms, e.g., bacteria co-existing with the yeasts in the same locations, and by the human immune system.
