💬 Helping Children Communicate: How ABA Builds Language, Gestures, and AAC Skills

Communication is essential for connection.

Whether through spoken words, gestures, signs, pictures, or devices — communication allows children to express their needs, share their thoughts, build relationships, and navigate the world around them.

For many families, communication delays are some of the earliest signs that their child may need support. A child may not be speaking yet, may use fewer words than expected, or may rely on crying, pointing, or leading others by the hand to communicate. Some children are highly verbal but struggle with social communication, back-and-forth conversation, or interpreting social cues.

No matter the child’s communication style, modern ABA therapy specializes in strengthening communication using approaches that are individualized, respectful, and empowering.

This article explains how ABA supports:

• early communication foundations
• alternative and augmentative communication (AAC)
• gestures and nonverbal communication
• functional communication training (FCT)
• speech and language milestones
• reducing frustration by increasing successful expression

Whether your child speaks, signs, uses AAC, or communicates in a multimodal way, ABA can help them build confidence and clarity in expressing themselves.

Communication Is More Than Words

Every child communicates — even when they are not speaking.

Communication can look like:

• pointing
• making sounds
• bringing items to a caregiver
• leading someone by the hand
• crying to show frustration
• gestures
• signs
• pictures
• AAC device use
• facial expressions
• eye gaze

ABA recognizes and respects all forms of communication.

The goal of therapy is not to force a child to speak verbally.

The goal is to ensure the child has a functional, reliable, and comfortable way to communicate their needs and thoughts.

In fact, research shows that:

➡ AAC and alternative communication do NOT prevent speech; they often support and increase it.

ABA therapy focuses on empowering the child, not limiting them to a single communication method.

The Foundation of Communication in ABA: FCT (Functional Communication Training)

Functional Communication Training (FCT) is one of the most effective ABA strategies for improving communication. FCT teaches children to use communication to replace behaviors that occur when a child is unable to express themselves.

For example:

• Instead of crying → “Help”
• Instead of pushing → “My turn”
• Instead of screaming → “I’m frustrated” or “All done”
• Instead of grabbing → “Give me” or an AAC request

FCT works because it:

• gives children control
• reduces frustration
• improves clarity
• strengthens parent-child connection
• builds communication independence

If a child’s challenging behavior is related to communication barriers, FCT is often one of the first strategies implemented.

Teaching Verbal Speech in ABA

For children developing verbal language, ABA supports:

• imitation of sounds
• single words
• expanding words into two-word combinations
• labeling items
• requesting
• answering questions
• conversational turn-taking
• functional sentence building

Teaching is done naturally during meaningful moments — not through forced drills.

Examples of naturalistic teaching:

• During snack time → teaching “more,” “eat,” or “juice.”
• During play → teaching “open,” “car,” “go,” “my turn,” or “help.”
• During reading → teaching “point,” “look,” “where,” or describing pictures.

Progress may begin with approximations, gestures, or signs. ABA meets children exactly where they are and builds from there.

Gestures, Eye Gaze & Early Communication Skills

Before children speak, they often use:

• eye contact (when comfortable)
• pointing
• reaching
• showing items
• waving
• nodding
• shaking the head “no”

ABA strengthens these pre-verbal skills through play-based routines.

For example:

• Encouraging a child to point to items they want
• Modeling gestures such as waving or signing
• Practicing turn-taking gestures like “your turn/my turn”
• Using preferred toys to build joint attention

These early skills are the building blocks of communication and social interaction.

AAC (Augmentative & Alternative Communication): All Communication Is Valid

Many parents worry that introducing AAC will stop or slow down speech development.

The truth is:

➡ AAC supports speech, reduces frustration, and boosts communication success.

➡ Children who need AAC often thrive once a device gives them a consistent voice.

➡ Speech may increase once pressure to speak is removed.

ABA uses AAC to empower children, including:

• speech-generating devices
• communication apps (tablets)
• picture boards (PECS)
• symbol-based systems
• core vocabulary boards

AAC helps children express:

• choices
• feelings
• preferences
• requests
• answers to questions

Therapists teach AAC the same way they teach spoken requests — through natural moments:

• Wanting a snack
• Wanting a toy opened
• Wanting a turn
• Needing help
• Wanting to stop an activity

AAC is not a “last resort.” It’s a tool — one that opens communication pathways early and effectively.

Multimodal Communication: A Modern, Neurodiversity-Affirming Approach

In modern ABA, therapists do not require children to use only one communication method.

Children can — and often do — communicate using multiple modes:

• Speech + gestures
• Speech + AAC
• Sign language + AAC
• Vocalizations + pointing
• Picture exchange + words

Multimodal communication:

• builds flexibility
• supports functional expression
• allows children to grow language in the way that feels natural to them

ABA follows the child’s lead and respects the way they choose to communicate.

Communication Challenges ABA Can Help With

ABA is particularly effective when communication delays lead to:

• frustration
• aggression
• tantrums
• self-injury
• elopement
• shutting down
• difficulty engaging with peers
• difficulty following directions

By teaching expressive and receptive communication skills, ABA reduces challenging behaviors and increases clarity for both child and caregiver.

How ABA Individualizes Communication Goals

Every child receives a communication plan based on:

• developmental level
• strengths
• sensory considerations
• preferences
• social comfort
• motivation
• accessibility

Some children begin with gestures.

Some with signs.

Some with AAC.

Some with spoken words.

ABA meets the child where they are — without pressure or force — and builds naturally through activities that matter to the child.

Natural Environment Teaching (NET): Communication Learned Through Real Life

Modern ABA heavily uses NET, which means teaching happens during:

• play
• routines
• meals
• bath time
• going outside
• reading
• transitions
• social activities

Children learn best in familiar, meaningful contexts — not at a table with flashcards.

NET strengthens:

• generalization
• independence
• natural language
• spontaneous communication

Sessions feel like play, not formal lessons — especially in early childhood.

Social Communication Skills Supported by ABA

Communication is more than words; it’s connection.

ABA helps children build social communication skills such as:

• responding to their name
• shared enjoyment
• initiating play
• turn-taking in conversations
• asking peers to play
• understanding personal space
• interpreting facial expressions
• using greetings

These skills help children feel more confident and connected at school, home, and in the community.

Reducing Frustration by Increasing Communication

Many challenging behaviors occur because the child simply cannot express:

• “I don’t want that.”
• “I’m tired.”
• “I’m overwhelmed.”
• “I need help.”
• “I want a break.”

By giving children clear ways to communicate, ABA reduces:

• meltdowns
• aggression
• self-injury
• crying
• screaming
• running away

Communication is empowerment.

Parent Involvement: The Most Important Part of Communication Growth

Parents learn how to:

• model communication at home
• reinforce new skills
• use AAC naturally
• understand communication attempts
• support expressive skills during routines
• reduce communication frustration
• encourage speech without pressure

When parents use consistent communication strategies, progress accelerates dramatically.
