Yes, toddlers can absolutely learn sign language, and many pick it up remarkably quickly once they start. Children between 12 and 36 months are in a prime developmental window for language acquisition, and their growing motor skills allow them to form signs more accurately than younger babies. A toddler who begins signing at 18 months, for instance, might learn 20 or more signs within just a few weeks of consistent practice, whereas a 6-month-old infant typically takes two to three months to produce their first recognizable sign. The toddler years offer unique advantages for sign language learning that parents often overlook.
Unlike infants who are still developing basic motor control, toddlers have the dexterity to form distinct hand shapes and the cognitive ability to connect symbols with meaning. They can also learn signs in context more readily, picking up “ball” at the playground or “dog” when meeting a neighbor’s pet. This natural curiosity and imitation drive makes the 12-to-24-month window particularly effective for introducing sign language. This article covers what makes toddlers successful sign language learners, the specific developmental factors at play, practical teaching strategies, common obstacles parents encounter, and how signing supports speech development during these crucial years. Whether your toddler is already talking or still working on verbal communication, signing offers a valuable communication bridge.

Why Do Toddlers Pick Up Sign Language Faster Than Infants?
Toddlers learn age.com/index.php/2026/01/24/is-baby-sign-language-good-for-toddlers/” title=”Is Baby Sign Language Good for Toddlers”>sign language more quickly than infants primarily due to developmental advantages in motor control, memory, and symbolic thinking. By 12 months, most children have developed the fine motor skills needed to distinguish between similar hand shapes, such as the difference between “more” and “ball.” Their working memory has also expanded, allowing them to retain and recall multiple signs rather than learning one at a time. Cognitive development plays an equally important role. Toddlers understand that objects exist even when out of sight and that symbols can represent real things. A 15-month-old who sees the sign for “milk” can connect it to the actual drink, the bottle, and the concept of drinking, all at once.
This symbolic reasoning is still developing in younger babies, which is why they take longer to make these connections. However, starting with an infant has its own benefits. Babies who begin signing at 6 to 9 months often have larger sign vocabularies by age two than toddlers who started later. The comparison is not about which age is better but about understanding that each stage brings different learning patterns. Toddlers learn faster per week, but infants who start earlier have more total exposure time before verbal speech takes over.
What Signs Work Best for Toddlers Just Starting Out
The most effective first signs for toddlers are those tied to their immediate interests and daily routines. Unlike infants who benefit most from basic needs signs like “milk” and “more,” toddlers respond well to signs for objects they find exciting, such as animals, vehicles, favorite foods, or beloved toys. A child fascinated by trucks will likely master that sign before learning “help” because motivation drives retention. Routine-based signs remain valuable but should expand beyond the feeding-focused vocabulary typically taught to babies. Toddlers benefit from signs for activities like “outside,” “play,” “book,” and “bath.” Action signs such as “jump,” “run,” and “stop” also resonate because toddlers are highly physical and can connect movement words to their own bodies. One limitation parents should recognize is that toddlers may resist formal teaching sessions. Unlike infants who accept repetition without complaint, toddlers often prefer learning through natural interaction rather than drills. If you find your toddler losing interest when you try to “practice” signs, shift to simply using signs during regular activities without making it feel like a lesson. A child who ignores a flashcard session might eagerly sign “cracker” when they see one in the pantry. ## How Toddler Sign Language Supports speech development Sign language does not replace speech development in toddlers; it supports and often accelerates it.
Research consistently shows that signing toddlers tend to have larger spoken vocabularies than non-signing peers by age two. This happens because signs give children a way to engage in language before their mouths and vocal cords can produce clear speech, building neural pathways for communication that transfer to verbal language. The process works through what linguists call multimodal language learning. When a toddler signs “dog” while also hearing the word and seeing the animal, three sensory channels reinforce the same concept. This multisensory input strengthens memory and understanding. Parents who sign also tend to speak more slowly and clearly, which gives toddlers better verbal models to imitate. A specific example illustrates this effect. Consider a toddler named Marcus who at 16 months could sign 15 words but only spoke three. By 24 months, he was speaking over 100 words and had stopped using most signs because he no longer needed them. His early signing did not delay his speech; it gave him a way to communicate during the months when his verbal abilities were still catching up to his comprehension.
Practical Strategies for Teaching Sign Language to Toddlers
The most effective approach for teaching toddlers differs from infant sign language instruction. Toddlers learn best through active participation rather than passive observation. Instead of simply showing a sign repeatedly, involve your toddler in using the sign immediately. When teaching “ball,” hand them the ball right after signing and encourage them to sign before each throw during a game. Comparing teaching methods reveals important tradeoffs. Formal sign language classes offer structured learning and social interaction with other signing families, but they require schedule commitment and may move at a pace that does not match your child’s interests.
home-based learning allows flexibility and customization but lacks the external accountability and peer modeling that classes provide. Many parents find a hybrid approach works best: learning foundational signs at home while occasionally attending group sessions for motivation and new vocabulary. Consistency matters more than intensity. A toddler who sees five signs used naturally throughout each day will progress faster than one who has a 20-minute dedicated practice session twice a week. Build signing into existing routines rather than adding new activities. Sign “shoes” when putting them on, “car” when heading to the garage, and “eat” at every meal. This contextual learning matches how toddlers naturally acquire language.
Common Challenges When Toddlers Learn Sign Language
The most frequent obstacle parents report is that their toddler understands signs but refuses to use them. This receptive-expressive gap is normal and does not indicate a problem. Many toddlers prefer pointing, grunting, or attempting verbal words over signing, especially if they have already developed verbal approximations. Forcing signing in these cases often backfires, creating negative associations with the communication tool. Another challenge arises when toddlers modify signs beyond recognition. Unlike adults learning a second language, toddlers do not aim for precision.
A child might sign “more” with flat hands instead of pinched fingers, or “dog” with a pat on their head rather than their leg. These adaptations are developmentally appropriate and should be accepted while parents continue modeling the standard version. Correcting a toddler’s sign execution typically discourages signing altogether. Parents should also recognize that signing will not resolve all communication frustration. A toddler who knows 30 signs will still have tantrums because they cannot express complex emotions or abstract wants. Signing reduces frustration by covering basic needs and common requests, but it does not eliminate the fundamental challenge of having a developing brain with limited communication tools. Setting realistic expectations prevents disappointment.
When Starting Sign Language With Toddlers May Not Be Worth It
For toddlers who are already verbal communicators, introducing sign language provides diminishing returns. A child who at 20 months is speaking 50 or more words and combining them into two-word phrases has already passed the stage where signing offers its greatest benefits. In these cases, the effort required to learn and consistently use signs may not justify the marginal communication improvement.
The exception is when signing serves a specific purpose beyond bridging the pre-verbal gap. Families with deaf relatives, children with speech delays or developmental differences, or parents interested in eventual ASL fluency have reasons to continue or start signing regardless of verbal development. For a typically developing toddler who is talking well, signing becomes optional enrichment rather than a communication necessity.
The Transition From Signing to Speaking
Most toddlers naturally phase out signing as their verbal skills improve, and this transition requires no active management from parents. Signs that once appeared constantly, like “more” and “milk,” simply stop appearing as children realize spoken words work faster and are understood by more people. This self-directed transition typically occurs between 18 and 30 months, depending on when signing started and how quickly verbal speech develops.
Some children maintain certain signs longer than others, particularly for words that are difficult to pronounce or concepts that feel more natural in sign form. A toddler might keep signing “please” even while speaking other words, or continue signing animal names during zoo visits. This bilingual-like retention is harmless and often fades by age three without intervention.
Conclusion
Toddlers are well-suited for learning sign language, often picking up signs faster than infants due to their developed motor skills, stronger memory, and advanced symbolic thinking. The 12-to-24-month window offers a practical opportunity to introduce signing, whether as a bridge to verbal speech, a tool for reducing frustration, or a foundation for ongoing ASL learning.
Success with toddler sign language depends on matching teaching approaches to toddler behavior patterns, choosing motivating signs over generic vocabulary lists, maintaining realistic expectations about what signing can and cannot accomplish, and recognizing when a child’s verbal development makes signing less necessary. For most families, even a modest vocabulary of 10 to 15 signs meaningfully improves daily communication during these transitional months.
