Its OK, George, really.

At the time he played with his rattle, he crawled around on the floor,
played in the dirt, never wiped his own ass, crapped in his pants, and
NEVER, EVER washed his hands.

He was also known to manually inspect the family dog's equipment, put
any available toy he was playing with in his mouth from time (no matter
where it had been), and if left his own devices, turn the garbage over
in the kitchen.

And yet... like so many.... he is just fine.

Others I have made the rattles for have had similar experiences.
