The handle on my sink came off.

The handle is being held down by a small piece under the Phillips head
screw. I am trying to back out the screw, but since it is not coming
out, I assume something else is turning. If I put my nephew under the
sink will he be able to clamp onto whatever is turning so I can back
out the screw?

Btw the faucet is a moen.
