3 Reasons Why Using Signs is Essential for Speech Development

While some may worry that using sign language might delay spoken words, research actually shows the opposite: signs support and enhance speech development—especially for young children and those with communication challenges. Sign language builds a strong foundation for expressive language, providing children with the tools they need to communicate clearly and confidently.

1. 🧠 Signs Support Brain Development

Using signs engages multiple areas of the brain, helping children build stronger neural connections related to language and memory. Research by Goodwyn, Acredolo, & Brown (2000) found that babies who used signs before speaking had larger spoken vocabularies and scored higher on IQ tests later in life. Sign language supports both receptive (understanding) and expressive (speaking) language development by giving the brain multiple pathways to process communication.

2. 🗣️ Signs Reduce Frustration and Encourage Speech

Before children are able to express themselves with words, signs offer a way to communicate their needs, feelings, and ideas. This reduces tantrums and frustration, and encourages more back-and-forth interactions between the child and adult. Over time, as children gain confidence and feel heard, many begin to pair signs with sounds and words, naturally transitioning to verbal language.

3. 🎵 Signs Pair Well with Music and Routines

Combining signs with songs and daily routines strengthens memory and makes language learning more fun and engaging. Signing key words in familiar songs like “Twinkle Twinkle Little Star” or during routines like “eat,” “more,” or “all done” gives children repeated, meaningful exposure to language in context. This repetition helps build understanding and promotes early word use.

🌟 Conclusion

Using signs does not delay speech—it builds the foundation for it. For babies, toddlers, and children with language delays, signing opens up a world of communication and boosts spoken language development in a fun, pressure-free way. Whether you're a parent, teacher, or therapist, incorporating signs into daily interactions can make a powerful difference.
