Teach your baby the sign for the word afraid in baby sign language with the following description and video.
Form both hands into open hands. Hold the hands in front of the torso with the fingers apart, the fingertips facing the opposite directions, and the palms facing the body. Move the hands back and forth. The face should express fear.
