Baby sign is distinct from sign language. Baby sign is used by hearing parents with hearing children to improve communication. Sign languages, including ASL, BSL, ISL and others, are natural languages, typically used in the Deaf community. Sign languages maintain their own grammar, and sentence structure. Because sign languages are as complex to learn as any spoken language, simplified signs are often used with infants in baby sign. Teaching baby signs allows for greater flexibility in the form of sign and does not require the parent to learn the grammar of a sign language. Baby signs are usually gestures or signs taken from the sign language community and modified to make them easier for an infant to form.
