To sign bring, take your two flat hands, palms facing up. Motion them together diagonally downward and to the front of your body, coming from the side of your dominant hand. It is as if you are indicating that you are bringing something somewhere.
Teach your baby or toddler the bring sign in the context of bringing food or a gift when you visit their grandparents, or if a visitor has brought something for your kid or family. Teach it as well when your toddler is instructed to bring something to preschool for "Show and Tell".
This is a useful flash card taught best in conjunction with preparations for actually bringing something to a family, school, or neighborhood event.
