Signing: The wash sign is made by making both hands into a fist, holding the two fists together, and twisting the two fists back and forth.
Usage: You can use the wash sign before you wash your babies hands. Babies can be a little fussy when it comes to washing up before meals, so doing the sign before hand can help make them prepared.
