Have you ever felt like your child with autism and PDA (Pathological Demand Avoidance) was making great progress, only to suddenly hit a wall? One day they're mastering new skills, and the next, it seems like everything has come to a complete stop. If this sounds familiar, you're not alone. As a parent who has been there, I want to talk about something many of us face but don't always have a name for: the developmental plateau.

What Is a Developmental Plateau?

A developmental plateau happens when a child who was previously showing steady progress in skills and development seems to stop advancing. For children with autism and PDA, these plateaus can be particularly noticeable and challenging for families to navigate.

Think of development like climbing a mountain. Sometimes the path is steep but steady, and other times you reach a flat stretch where it doesn't feel like you're gaining any elevation. That flat stretch is the plateau – it doesn't mean the journey has ended; it's just a different part of the path.

When I saw my friend's son hit his first major plateau around age seven, I remember how confused and worried she was. He had been making such wonderful progress with his speech and social skills, and then suddenly, nothing new seemed to be happening for months. She wondered if they were doing something wrong or if this was just part of the journey.

Why Developmental Plateaus Happen

Developmental plateaus with autism are actually quite common. These plateaus can happen for several reasons:

Brain Development Patterns

Children with autism and PDA often have unique patterns of brain development. Sometimes their brains are busy working on internal connections that we can't easily see from the outside. While outward progress might seem stalled, important neural pathways could be strengthening behind the scenes.

Energy Redistribution

Think about when you learn a new skill, like riding a bike. At first, it takes all your concentration. Later, once you've mastered it, you hardly think about it. Children with autism and PDA sometimes need to consolidate skills they've already learned before taking on new ones. They're redistributing their energy.

Children with autism may need longer to process and integrate information before moving forward. It's like they're taking time to thoroughly learn one concept before they're ready to build on it.

Increased Complexity of Skills

As children get older, the skills they need to learn become more complex and nuanced. For example, early language might involve learning single words, but later language development requires understanding idioms, humor, and social context – areas that are often challenging for children with autism and PDA.

The social and communication demands increase exponentially as children enter school age years, which can make progress seem slower even when development is continuing.

Stress and Environment

Changes in routine, school environments, or family situations can also contribute to plateaus. Children with PDA and autism often thrive on predictability, and disruptions can temporarily impact their ability to learn new skills.

Common Areas Where Plateaus Occur

In my experience both as a parent and working with other families, I've noticed plateaus commonly occur in these areas:

Social Communication

A child might master basic conversation skills but struggle with the leap to more nuanced social communication like understanding implied meanings or navigating group dynamics.

Academic Skills

Many parents notice their child learns to read but then plateaus before developing reading comprehension. Or they may excel at math facts but struggle when concepts become more abstract.

Emotional Regulation

Your child might develop basic emotional awareness but hit a plateau when it comes to implementing coping strategies in real-time stressful situations.

Independence Skills

Many children with autism and PDA show plateaus in developing self-care and daily living skills, especially as these tasks become more complicated or have multiple steps.

My Family's Experience with Plateaus

When my daughter hit a plateau with her reading skills, I remember feeling frustrated. She had been an early reader, quickly picking up sight words and phonics. But suddenly, she couldn't seem to progress to chapter books or develop deeper comprehension.

What I didn't realize then was that her brain was actually working overtime. While her reading advancement seemed stalled, she was actually developing important processing skills. She was learning to connect ideas across pages, visualize scenes, and predict outcomes – all happening internally without obvious external signs.

Six months later, she suddenly began devouring chapter books and discussing character motivations in ways that amazed me. That plateau hadn't been a stop in development; it had been an important period of internal growth.

How to Support Your Child During a Plateau

Maintain Perspective

Remember that development isn't always linear. Kids do well if they can. If your child isn't progressing in a particular area, it's not because they don't want to – something is making it difficult.

Focus on Strengths

During plateaus, it helps to shift focus to your child's areas of strength and special interests. These can provide important confidence boosts and may even help development in other areas.

A mother in my support group shared how when her son hit a plateau with his social skills, they leaned into his passion for dinosaurs. By connecting with other dinosaur enthusiasts and joining a paleontology club, he found motivation to practice social interaction in a context that felt safe and engaging for him.

Adjust Expectations (Not Lower Them)

Sometimes we need to adjust our timeline, not our expectations. Development may take longer, but that doesn't mean it won't happen.

Development in autism often follows its own timeline, which doesn't necessarily match typical developmental schedules. Our children are running their own race, not competing in someone else's.

Look for Micro-Progress

During plateaus, I've learned to celebrate tiny steps forward that I might have overlooked before. Maybe your child isn't mastering new math concepts, but they're showing slightly better focus during homework time. These micro-improvements often signal that development is still happening, just more subtly.

Consider Environmental Adjustments

Sometimes plateaus indicate that your child needs a different approach or environment. This might mean adjusting teaching methods, finding new therapists, or modifying home routines.

When my daughter's progress with speech therapy plateaued, switching to a therapist who incorporated her special interest in art made a tremendous difference. Suddenly, she was motivated to communicate in new ways.

When to Seek Additional Support

While plateaus are normal, sometimes they signal that additional support might be helpful. Consider reaching out to professionals if:

• The plateau lasts for more than 6-12 months with no signs of micro-progress

• Your child seems to be losing previously mastered skills

• The plateau is accompanied by new challenging behaviors or signs of distress

• Your parental intuition tells you something more might be going on

  
  

When progress stalls, it's often helpful to bring in fresh perspectives while remembering that the child is still the same person with the same potential.

Finding Hope in the Plateau

One of the most important things I've learned as a parent of a child with autism and PDA is that plateaus are not permanent. They are resting places on a longer journey.

Development in autism may not follow a straight line, but that doesn't mean progress isn't happening. Some of the most dramatic breakthroughs I've witnessed in my children came after long plateaus – almost as if their minds had been quietly gathering strength before making a significant leap forward.

The Hidden Growth Within Plateaus

Research now suggests that what looks like a developmental plateau with autism from the outside may actually be a period of important internal development. During apparent plateaus, children with autism are often developing important neural connections that will later translate to visible skills.

This reminds me of how bamboo grows. For the first several years after planting, bamboo shows minimal above-ground growth. But during this time, it's developing an extensive root system. Then suddenly, it can grow several feet in just weeks. Our children's development can follow similar patterns – periods of invisible growth followed by surprising spurts of progress.

Different, Not Less

During plateaus, I find comfort in remembering that our children are "different, not less." Their development may follow different pathways and timelines, but that doesn't diminish their capabilities or potential.

When we embrace this perspective, plateaus become less frightening and more intriguing – what invisible work might be happening below the surface? What strengths might be developing that we haven't even recognized yet?

Partners in the Journey

As parents, we are not just observers of our children's development but active partners in it. By staying connected, patient, and creative during plateaus, we create an environment where growth can happen in its own time and way.

I've found that my most important job during plateaus isn't pushing for progress but being fully present with my child where they are right now. This presence creates safety, and from safety comes the confidence to grow and change.

Next Steps

Parenting a child with autism and PDA is both challenging and rewarding. If you're looking for more practical strategies and insights, I've compiled extensive research and personal experience in my book, "A Practical Parent's Guide to PDA and Autism."  This resource provides concrete approaches tailored specifically to parents and caregivers of children who experience both autism and PDA.

As a parent juggling therapy appointments, IEP meetings, and the daily challenges of raising a child with PDA, I know you barely have time to sit down, let alone read a book. That's exactly why I've made "A Practical Parent's Guide to PDA and Autism" available as an audiobook you can listen to during school drop-offs, while making dinner, or during those precious few minutes alone in the car. Transform your "lost time" into learning time by grabbing the audiobook here: US, UK, Australia, Canada, France, and Germany.

I wrote this book because I needed it myself and couldn't find anything like it. It offers practical, parent-to-parent advice based on both research and my own real-life experience raising a child with PDA, with specific chapters dedicated to understanding and preventing burnout. The strategies I share have helped thousands of families reduce stress and build more harmonious relationships with their neurodivergent children. As parents walking this path, we need real solutions from someone who truly understands—not just theory, but practical approaches that work in everyday life with our wonderful, complex children.
