Baby Sign for Pacifier
Make a fist with your dominant hand. Then, extend your pointer finger from the fist while leaving the finger curled. The first knuckle in your finger should be pointing up with your hand facing your non-dominant side. Next, place the pad of your thumb on the side of your pointer finger that is closest to your thumb, so your thumb is relaxed into the hook created by your index finger. Lastly, bring your hand to your mouth and rest your thumbnail on your lips.
