Signing: The gift sign is a natural sign, looking like you are giving someone a gift. Make both hands into a fist with your index finger extended and curled. Starting with your hands close to your body, move them away from your body.
Usage: You can start to teach baby about the idea of a gift by making small presents to baby and making the gift sign. And encourage baby to make the sign to you before they give you something. This also starts to introduce baby to the idea of sharing, giving and receiving.
