Teach your baby the sign for the phrase clean up in baby sign language with the following description and video. Use your dominant hand to form the signs.
Baby sign language, baby sign, or baby signing is used by hearing parents with pre-verbal hearing children to improve communication. My baby signs are based on ASL (American Sign Language) signs. Baby signing is distinct from sign language.
Repeat the sign for clean. Hold one hand in front of the chest with the palm facing up. Rub the palm of the other hand over the palm of the first hand.
