The wash sign is generally made by making the dominant hand into a fist, keeping the non-dominant hand flat, with palm facing up, while the dominant hand makes counter-clockwise circles on the palm.
If you want to sign wash hands, then you form both hands into fists and rub them against each other in alternative circular movements.
You can use thewash 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 beforehand can help make them prepared.
