Baby signing and learning ASL are two genuinely different topics. Here's the actual difference, and where each one fits.
Start Free →"Sign language for babies" almost always means one specific thing: baby sign language, a small set of simple gestures taught to hearing infants and toddlers as a communication bridge before they can speak clearly. It is not the same undertaking as learning ASL, and conflating the two leads to mismatched expectations — a parent looking for a way to reduce toddler frustration over wanting more crackers is after something very different from a parent looking for their child to eventually hold a real conversation in American Sign Language.
Baby signing typically covers a handful of practical, high-frequency words — more, milk, all done, eat, sleep — chosen because they cover the specific frustrations of a pre-verbal child who has needs and no reliable way yet to express them. A baby's fine motor control for gesture usually develops well before the vocal control needed for clear speech, so signing gives them a functional shortcut to communicate a specific want before words are available. Most babies drop the signs naturally once spoken vocabulary catches up and takes over as the easier, faster channel — the signs aren't meant to be a permanent communication system, just a temporary bridge.
Baby sign language often borrows individual signs from ASL — that's usually where the specific hand shapes for "more" or "milk" originate — but borrowing a handful of vocabulary items isn't the same as the language itself. ASL is a full, grammatically complete language with its own sentence structure, word order, and facial grammar; baby signing uses isolated single-word signs with none of that structure, the same way a baby saying "milk" isn't demonstrating English grammar. A baby who learns to sign "more" hasn't started learning ASL any more than a baby who says "milk" has started learning formal English.
Baby signing typically starts around 6-9 months, roughly when a baby has the fine motor control to reliably produce a simple gesture, even if they don't sign back for a few more months after that — modeling the signs consistently matters more than hitting an exact starting age. Learning ASL as a real language, the kind with vocabulary progression and grammar, is a different project on a different timeline, better suited to a child old enough to engage with structured lessons — which is a much later stage than the pre-verbal window baby signing addresses. A family interested in both can treat them as two separate, sequential undertakings rather than one continuous track.

No. Baby sign language borrows a handful of individual signs, often from ASL, but it isn't ASL itself and doesn't teach ASL grammar, sentence structure, or a real vocabulary.
Most guidance suggests starting around 6-9 months. Consistency in modeling the signs matters more than the exact starting age.
It can give a small head start on a handful of signs, but it isn't a substitute for learning ASL's actual grammar and vocabulary later on.
No — it's built for kids old enough to engage with a structured skill path, roughly early elementary and up, not as a baby-signing tool for pre-verbal infants.
