Signing: Garbage looks like you are picking something up, and then throwing it away. Put your non-dominant hand out flat with palm up in front of your body. You dominant hand mimes picking something up from the flat non-dominant hand, then cast it off to the side as if throwing it in the garbage.
Usage: Like puppies, babies often find an unsettling level of fascination with the garbage bin. As they grow older they will enjoy putting things in the garbage bin instead of rooting around in it. You can use the sign for garbage to tell them to put something in the trash.
