How Positive Behaviour Support Helped a Toddler Thrive

Leo (name changed for privacy) is a playful and energetic three-year-old boy who loves building blocks and anything related to trains. Like many toddlers his age, Leo was eager to interact with his environment, but he faced significant hurdles. Diagnosed with developmental delays and early signs of autism spectrum disorder around 18 months of age, Leo struggled greatly with functional communication.

At three years old, Leo was predominantly non-verbal. Instead of using words or gestures to express his needs, he relied on physical responses. His background includes a loving family who noticed early on that standard parenting interventions weren't bridging the communication gap. As Leo grew, the frustration of being misunderstood began to manifest in intense, daily behavioural episodes.

The family turned to daar for professional guidance, seeking a compassionate, evidence-based intervention. They needed a holistic approach to child behaviour and progress that would not just stop difficult behaviours, but actively teach Leo the skills he lacked. Our clinicians stepped in to evaluate Leo’s needs, build a strong baseline understanding of his current abilities, and formulate a targeted, play-based intervention plan.

The Challenge

The primary behavioural concerns revolved around Leo’s severe meltdowns, which occurred daily. Because he lacked the foundational communication skills to request a toy, ask for a snack, or signal that he was overwhelmed, his default reaction was to scream, throw objects, or drop to the floor. These episodes could last 20 to 45 minutes and were easily triggered by everyday transitions, such as moving from playtime to mealtime or leaving the house for school.

The impact of these behaviours was significant across all environments:

• At Home: The household revolved around trying to predict and prevent Leo’s meltdowns. His parents noted high levels of exhaustion, as even basic routines like brushing teeth, getting dressed, or sitting securely at the dinner table required immense negotiation and often resulted in intense distress. The family felt they were walking on eggshells, compromising their collective quality of life.
• At School/Childcare: Leo’s transition to a mainstream childcare centre highlighted his social and emotional barriers. When peers approached him, he would often become overwhelmed and push them away. He struggled to participate in group activities or follow the educators' instructions. The childcare staff were concerned for his safety and the safety of the other children, noting that without 1-on-1 supervision, Leo’s physical reactions to frustration were escalating.

The core of the challenge was not that Leo was simply "acting out," but rather that he experienced a profound gap in expressing his needs and navigating a fast-paced sensory world. He needed a bridge to effective communication and self-regulation.

daar Therapy Approach

To support Leo and his caregivers, daar implemented a comprehensive plan rooted in positive behaviour support. Our goal was never to force compliance or eliminate his personality, but to provide him with the specific tools he needed to safely communicate, play, and interact with the world around him.

The clinical team started with a thorough functional behaviour assessment to understand exactly what was triggering Leo's meltdowns. We found that the vast majority were rooted in a desire for specific items (like his trains) or a desire to escape overstimulating situations (like crowded rooms at childcare).

With this understanding, our clinicians introduced a customised, play-based behaviour therapy for children that prioritised building a genuine connection first. The therapy approach was broken down into several key methodologies:

• Rapport and Play-Based Pairing: For the first few weeks, the therapist placed no demands on Leo. Instead, the focus was entirely on play and pairing the therapist with fun, engaging experiences. By following Leo’s lead with his favourite trains and building blocks, the therapist became a trusted partner rather than a demanding authority figure.
• Socialised Behaviour Therapy Integration: We recognised that Leo needed support not just in isolation, but in context. The therapist implemented socialised behaviour therapy by actively conducting sessions where Leo naturally interacts with others—both at his home with his siblings and during embedded sessions at his childcare centre. This allowed the therapist to guide his social interactions in real-time, modelling sharing and turn-taking without removing him from the natural environment.
• Functional Communication Training (FCT): Instead of focusing solely on reducing throwing or screaming, the team focused on teaching a replacement skill. Using positive behaviour support, Leo was taught to use simple sign language and a picture exchange system to hand a picture of a "train" or "snack" to his therapist or parents when he wanted something. As soon as he used the functional tool, he was immediately rewarded with the requested item, reinforcing the power of communication.
• Structured Transitions and Routines: To reduce anxiety around transitions, the therapy team introduced visual schedules for Leo. A simple visual timer and a "first/then" board (e.g., "First put on shoes, then go to the park") were utilised at home and integrated into his childcare classroom.

By upskilling Leo's parents and his childcare educators on these exact strategies, the daar team ensured that Leo experienced a consistent, predictable environment no matter where he was.

Results & Progress

Over six months of consistent, play-based therapy, Leo’s trajectory changed dramatically. By tracking daily data, the behaviour analysis team could clearly measure his skill development and behavioural reduction, proving the vital link between tailored child behaviour support and progress.

One of the most notable improvements was his communication. Within the first two months, Leo independently learned to use five different picture cards to request his needs. By the sixth month, he was using over twenty specific requests and had even begun pairing spoken approximations of words with his cards. Because his needs were finally being met through clear communication, his reliance on aggressive physical responses plummeted.

At childcare, Leo's specific examples of progress were heartwarming to the staff. Previously, he would push peers who approached his play area. With the implementation of his socialised behaviour plan, Leo began passing blocks to his peers during supervised structured play.

To clearly measure the outcomes, daar tracked specific data points comparing his baseline (Month 1) to his development after a period of intervention (Month 6).

Key Outcomes

The overarching results extended far beyond just the numerical data. The true success of the program was seen in the transformation of the family's daily life and Leo's newfound happiness.

1. Reduction in Caregiver Stress: Leo's parents reported feeling equipped and empowered. Having a proactive plan meant they were no longer living in reactive "survival mode." They could finally enjoy taking Leo out to the park, knowing they had the tools (visual schedules and communication cards) to manage transitions smoothly.
2. Increased Childcare Participation: The successful collaboration between the daar clinicians and the childcare educators meant Leo was no longer at risk of being removed from the program. He was integrated safely into group learning and began forming early friendships.
3. Foundation for Future Independence: By addressing his needs early on, the behaviour therapy for children provided by our team laid a critical foundation. Leo's newly developed functional communication acts as the ultimate stepping stone for advanced language development and stronger emotional regulation in the years to come.
4. Embracing Strengths rather than Masking: The most vital outcome is that Leo is still the same train-loving, energetic boy he always was. His therapy was strength-based. He simply learned a safer, more effective way to bridge his inner world with the people around him.

Conclusion

Early support can permanently alter a child's developmental trajectory for the better. By focusing on strengths, understanding the function of behaviour, and creating a supportive environment, toddlers like Leo can dramatically overcome immense hurdles. It takes time, consistency, and the right strategic guidance, but seeing a child suddenly able to communicate their needs to the world makes every step of the journey worthwhile.

As Leo's mother shared:

"Before we started with daar, our home was constantly stressful. We knew Leo was incredibly smart, but he was trapped without a way to tell us what he needed. The team didn't just 'fix' his behaviour; they taught him how to speak to us in his own way. Now, seeing him smile and successfully ask for his toys without tears is the greatest gift our family could have asked for."

If your child is facing communication delays, struggling with severe meltdowns, or requiring support navigating social environments, you do not have to figure it out alone. Early intervention makes all the difference in child behaviour and progress.
