Unexpected situations are part of everyday life. A favourite activity may be cancelled, a teacher may be absent, a family outing may change because of the weather, or a familiar routine may suddenly look different. Adults often adjust to these situations without much preparation, but for children, unexpected changes can sometimes feel confusing, frustrating, or overwhelming.
For children with autism, developmental differences, communication needs, or challenges with flexibility and emotional regulation, unexpected events may be particularly difficult to navigate. Predictable routines can provide comfort and help children understand what is expected. When something interrupts that predictability, a child may not immediately know how to respond.
Applied Behaviour Analysis, commonly known as ABA therapy, can help children develop practical skills for navigating uncertainty. Through individualized teaching, communication support, gradual exposure to manageable changes, emotional regulation strategies, and positive reinforcement, children can learn that an unexpected situation does not necessarily mean the entire day has gone wrong.
The goal is not to remove routines or deliberately make a child’s environment unpredictable. Routines can be extremely valuable. Instead, ABA therapy can help children develop additional skills so that when unavoidable changes happen, they have strategies for understanding the situation, communicating what they need, and deciding what to do next.
Why Unexpected Situations Can Be Challenging
Predictability helps children make sense of their environment.
When a child knows what is going to happen, they can prepare for the activity and understand what is expected of them. A familiar routine reduces the number of decisions they need to make and may make everyday responsibilities easier to manage.
Unexpected situations remove some of that predictability.
A child may suddenly need to process:
- What changed
- Why the change happened
- What will happen instead
- Whether a preferred activity is still available
- What they are expected to do next
- How long the new situation will last
Processing all of this information at once can be difficult.
ABA therapy can help by teaching concrete responses to uncertainty rather than simply expecting children to “be flexible.”
Understanding Flexibility as a Skill
Flexibility is often discussed as though children either have it or they do not. In reality, flexibility involves several skills that can develop over time.
A flexible response may require a child to:
- Notice that something has changed
- Understand the new information
- Manage disappointment
- Ask appropriate questions
- Consider an alternative
- Transition to a different activity
- Continue with the day
Breaking flexibility into smaller components makes it easier to teach.
A child who struggles with a changed plan may not necessarily need to work on every part of this process. They might understand the change but need additional support communicating disappointment. Another child may communicate effectively but have difficulty transitioning to the alternative activity.
Individualized ABA therapy can focus on the specific skills that are most relevant.
Identifying Situations That Are Difficult for the Child
Before teaching strategies, it is helpful to understand which unexpected situations are particularly challenging.
Families and ABA professionals may notice patterns involving:
- Changes in daily schedules
- Cancelled preferred activities
- Different foods or clothing
- Unfamiliar locations
- Substitute teachers
- Visitors at home
- Changes in transportation
- Waiting longer than expected
- Changes in plans
- Unavailable preferred items
- Unexpected noises
- Community disruptions
Understanding these patterns helps adults create meaningful goals.
The purpose is not to eliminate every difficult situation. It is to identify where additional preparation, communication, or coping skills may help the child participate more successfully.
Teaching the Concept That Plans Can Change
One useful starting point is helping children understand that plans sometimes change.
This concept can be introduced during calm moments rather than waiting until a stressful situation occurs.
For example, a child may learn simple language such as:
“Sometimes plans change.”
“We can choose something else.”
“We can check what happens next.”
These phrases can become familiar reminders when an unexpected event eventually occurs.
For children who benefit from visual information, a visual symbol for “change” can also be incorporated into schedules.
Using Visual Schedules to Explain Changes
Visual schedules are commonly used to make daily activities more predictable. They can also be useful for teaching flexibility.
Suppose a child’s afternoon schedule originally shows:
Snack
Park
Homework
Dinner
If rain makes the park unavailable, the visual schedule can be updated so the child can clearly see the new plan.
Instead of relying entirely on a verbal explanation, the child can see that the park has changed to an indoor activity while the rest of the routine remains familiar.
This can communicate an important message: one part of the schedule changed, but everything else did not disappear.
Teaching Children to Check What Happens Next
When something unexpected occurs, children may focus heavily on what is no longer happening.
Teaching them to identify what comes next can provide direction.
A child might learn to:
- Notice that the plan changed.
- Check the schedule.
- Ask what happens next if necessary.
- Move toward the next activity.
This simple routine can provide structure within an unpredictable moment.
Eventually, children may become increasingly able to use the strategy without adult reminders.
Supporting Functional Communication
Communication is one of the most important tools a child can use during unexpected situations.
Children may need ways to communicate:
“I don’t understand.”
“What happened?”
“What are we doing instead?”
“I need help.”
“I need a break.”
“I’m disappointed.”
“Can you tell me what’s next?”
For children who do not primarily use spoken language, equivalent communication can be supported through gestures, pictures, signs, or communication devices.
Having an effective way to express confusion or discomfort can reduce the need for behaviour to serve as the child’s primary form of communication.
Teaching Children to Ask Questions About Changes
Unexpected situations naturally create questions.
Instead of expecting children to quietly accept every change, ABA therapy can teach them how to seek useful information.
For example, a child may learn to ask:
“When are we going?”
“Can we do it tomorrow?”
“What are we doing instead?”
“How long do we have to wait?”
These questions can make an uncertain situation more understandable.
They also support self advocacy because the child learns that they can actively seek information rather than simply waiting for adults to decide everything.
Helping Children Communicate Disappointment
Flexibility does not mean children should never feel disappointed.
If a child has been looking forward to visiting a playground and the outing is cancelled, disappointment is a reasonable emotional response.
ABA therapy can help children communicate that feeling in a functional way.
Depending on the child’s communication abilities, they may learn to say:
“I’m disappointed.”
“I really wanted to go.”
“I’m upset that the plan changed.”
Acknowledging emotions while teaching appropriate responses creates a healthier approach than expecting children to appear happy about every change.
The goal is not to remove the feeling. It is to help the child navigate what happens after the feeling occurs.
Developing Emotional Regulation Strategies
Unexpected situations can sometimes produce strong emotional reactions.
Children can benefit from having regulation strategies available before those moments occur.
Depending on the individual child, useful strategies might include:
- Taking a short break
- Using a quiet space
- Taking slow breaths
- Engaging in an appropriate calming activity
- Using sensory supports
- Asking for additional information
- Communicating a need for assistance
ABA professionals and families can identify which strategies are actually useful for the individual child.
These strategies should be practiced during calm periods so they are familiar when the child genuinely needs them.
Gradually Introducing Small Changes
Flexibility can be practiced through manageable changes rather than sudden, overwhelming disruptions.
For example, a familiar activity might occasionally involve:
- Using a different cup
- Choosing a different seat
- Completing two familiar tasks in a different order
- Taking a different appropriate route
- Playing a familiar game with a small variation
The difficulty of these changes should be individualized.
The purpose is not to intentionally create distress. Instead, carefully planned opportunities can help children discover that small changes are manageable and that they still have strategies available when something is different.
Reinforcing Successful Responses to Change
Positive reinforcement can help strengthen flexible responses.
Adults can recognize when children:
- Accept an alternative
- Ask an appropriate question
- Use a coping strategy
- Transition after a change
- Communicate disappointment appropriately
- Solve an unexpected problem
Specific feedback can be especially helpful.
For example:
“You were disappointed when the activity changed, but you asked what we could do instead.”
This identifies the exact behaviour the child used successfully.
Over time, the natural benefits of coping effectively can become increasingly meaningful.
Teaching Alternative Choices
One useful strategy for managing unexpected situations is learning that there may be more than one acceptable option.
If a preferred activity becomes unavailable, children can practice selecting an alternative.
For example:
The playground is closed. Would you like to walk or play indoors?
The preferred snack is unavailable. Would you like one of these two alternatives?
The usual game cannot be played. Which different activity would you like?
Offering manageable choices gives the child some control within a situation they did not choose.
This can support both flexibility and decision making.
Building Problem Solving Skills
Unexpected situations are often problems that need solutions.
ABA therapy can help children develop a simple problem solving process.
A child might learn to ask:
What happened?
What do I need?
What choices do I have?
Do I need help?
What can I try next?
For younger children or those needing additional support, this process can be represented visually.
As problem solving improves, adults can gradually provide less direction and encourage children to generate their own solutions.
Teaching Waiting Skills
Not every unexpected situation requires a new plan. Sometimes the child simply needs to wait longer than expected.
Waiting can be difficult because the endpoint may not feel clear.
Children can be taught strategies such as:
- Using a timer
- Checking a visual countdown
- Choosing an appropriate activity while waiting
- Asking how much longer
- Using a calming strategy
Learning how to manage delays can make many everyday situations easier, including appointments, transportation delays, community outings, and family activities.
Preparing for Changes at School
School environments contain many potential changes.
A child might encounter:
- A substitute teacher
- A classroom change
- A cancelled activity
- An altered lunch schedule
- A different seating arrangement
- An unexpected assembly
- A change in transportation
Children can practice useful responses before these situations happen.
They may learn to check a classroom schedule, ask a teacher what comes next, use an appropriate regulation strategy, or transition to an alternative activity.
When families, ABA professionals, and educators use compatible strategies, children may find it easier to apply what they have learned across settings.
Managing Unexpected Situations at Home
Home is often the child’s most familiar environment, making it an important place to practice flexibility.
Unexpected events might include:
- A family member arriving late
- A meal changing
- A preferred item being unavailable
- An appliance not working
- A planned outing being cancelled
- Bedtime happening differently because of an event
Parents can use these moments to support communication and problem solving.
Instead of immediately solving every problem, an adult can sometimes guide the child through identifying what happened and considering what can happen next.
Managing Changes in the Community
Community environments are naturally less predictable than home.
Stores may be busy. A restaurant may not have a preferred item. A playground may be closed. Transportation may be delayed. An activity may take longer than expected.
These experiences provide opportunities to generalize flexibility skills.
Before an outing, families can prepare children for the possibility of change without creating unnecessary worry.
For example:
“We’re going to the library. If the book we want isn’t available, we’ll choose another one.”
This provides a clear alternative before the situation occurs.
Using Role Play to Practice Unexpected Events
Some situations can be practiced safely through role play.
An adult might present a scenario such as:
“Your favourite game isn’t available. What could you do?”
Or:
“The teacher says today’s activity has changed. What could you ask?”
Role play gives children time to think about possible responses without the emotional intensity of a real unexpected event.
Practice can include communication, problem solving, asking for help, and choosing alternatives.
Using Social Narratives When Appropriate
Some children benefit from short visual or written narratives explaining how changes may happen and what they can do.
A narrative might explain that sometimes plans change because of weather, illness, schedules, or other circumstances.
It can then introduce appropriate responses such as:
- Asking what happens next
- Choosing another activity
- Requesting a break
- Talking about feelings
- Checking the updated schedule
The narrative should be individualized and written at a level the child can understand.
Helping Children Recover After Difficult Moments
Learning to manage unexpected situations does not mean every situation will go smoothly.
Children may still become upset, need additional time, or require support.
An important skill is learning how to recover afterward.
Once the child is calm, adults can help them understand what happened without turning the conversation into criticism.
They might review:
What changed?
What was difficult?
What helped?
What could we try next time?
This turns a challenging experience into information that can guide future teaching.
Avoiding Too Much Reassurance or Prompting
Adults naturally want to help when a child appears uncertain.
However, if an adult immediately provides repeated reassurance or tells the child exactly what to do every time something changes, the child may have fewer opportunities to use their own skills.
As appropriate, adults can gradually shift from direct instructions to questions such as:
“What can you check?”
“What could you do next?”
“Do you need help?”
This encourages the child to participate in solving the situation.
Maintaining Helpful Routines
Teaching flexibility does not require removing routines.
Predictable routines can support communication, learning, independence, and emotional well being.
The goal is balance.
Children can have dependable routines while also learning that occasional changes are manageable.
In fact, having a generally predictable environment may make it easier to practice flexibility because the child has a stable foundation from which to explore manageable variations.
Respecting Genuine Needs
Not every difficulty with change should automatically be treated as behaviour that needs to disappear.
A child’s response may communicate important information.
The environment may be too loud. Instructions may be unclear. The child may be tired, hungry, uncomfortable, or overwhelmed. The new expectation may genuinely be too difficult.
ABA support should consider what the behaviour communicates and whether environmental adjustments are appropriate.
Flexibility should never mean teaching children to ignore genuine discomfort or stop advocating for themselves.
Generalizing Flexibility Across Different Situations
A child may learn to handle one type of change but still need support with another.
For example, successfully accepting a different snack does not necessarily mean the child will immediately manage a sudden school schedule change.
Generalization requires opportunities to practice related skills in different contexts.
Children can gradually use flexibility strategies with:
- Different adults
- Different routines
- Different locations
- Different types of changes
- Different levels of support
This helps the skill become useful in everyday life rather than remaining limited to a specific therapy activity.
The Role of Parents and Caregivers
Families are important partners in developing flexibility because they experience everyday changes alongside the child.
Parents can support progress by:
- Maintaining clear routines
- Preparing children for known changes
- Teaching communication skills
- Offering manageable alternatives
- Reinforcing successful coping
- Modeling calm problem solving
- Allowing children to express disappointment
- Giving appropriate opportunities to solve problems
Parents can also share observations with ABA professionals about which situations are becoming easier and which continue to create difficulty.
This information can help keep goals relevant to the child’s actual life.
Modeling Healthy Responses to Unexpected Events
Children learn a great deal by observing adults.
Parents can model flexible problem solving during ordinary situations.
For example:
“We planned to go outside, but it’s raining. I’m disappointed, but let’s see what else we can do.”
Or:
“The store doesn’t have what I wanted. I’ll choose another option.”
These examples show children that adults also experience disappointment and inconvenience.
More importantly, they demonstrate that an unexpected event can be acknowledged and managed without pretending it is enjoyable.
Celebrating Small Improvements
Progress with flexibility can happen gradually.
Meaningful milestones may include:
- Tolerating a small schedule change
- Asking what happens next
- Accepting an alternative activity
- Communicating disappointment appropriately
- Using a regulation strategy
- Recovering more quickly from a change
- Solving an unexpected problem
- Asking for help independently
Each achievement represents an important step.
Recognizing these moments can help children build confidence in their ability to navigate uncertainty.
How Managing Unexpected Situations Supports Independence
As children grow, adults cannot predict or control every experience they will encounter.
School, friendships, community activities, work, travel, and daily responsibilities all involve some level of uncertainty.
Developing flexibility can therefore support broader independence.
Children who learn how to respond to unexpected situations may become better able to:
- Communicate their needs
- Solve problems
- Make decisions
- Manage disappointment
- Ask for assistance
- Consider alternatives
- Participate in unfamiliar environments
- Recover after setbacks
These abilities can continue developing throughout childhood and into adulthood.
Building Confidence in an Unpredictable World
One of the most valuable outcomes of learning to manage unexpected situations is confidence.
Children do not need to know exactly what will happen every moment in order to feel capable.
Instead, they can gradually learn:
“I can ask what is happening.”
“I can tell someone how I feel.”
“I can choose another option.”
“I can ask for help.”
“I can handle a change with support.”
This confidence can make new experiences feel more approachable.
Rather than relying entirely on the environment remaining unchanged, children begin developing strategies they can carry with them.
Final Thoughts
Unexpected situations are an unavoidable part of everyday life. Plans change, preferred activities become unavailable, schedules shift, people arrive late, environments become different, and new challenges appear without warning. While these moments can be difficult for some children, flexibility and problem solving are skills that can develop gradually with appropriate support.
ABA therapy can help children navigate unexpected situations by teaching concrete strategies rather than simply expecting them to accept change. Visual schedules, functional communication, emotional regulation strategies, alternative choices, problem solving, positive reinforcement, role play, and gradual practice can all contribute to stronger coping skills.
Effective support also recognizes that children are allowed to experience disappointment. The goal is not to eliminate emotional reactions or require children to appear comfortable with every change. Instead, children can learn how to communicate those feelings, understand what has changed, identify what happens next, and access support when they need it.
Families can strengthen these abilities through everyday experiences while continuing to provide the routines and predictability that help children feel secure. Over time, small successes can develop into greater confidence.
A child who once struggled significantly when an activity changed may eventually learn to ask what is happening instead. A child who depended on an adult to solve every unexpected problem may begin suggesting alternatives independently. Another child may learn to communicate that they need a break before returning to the situation.
These individual achievements are meaningful because they support something larger than simply tolerating change. They help children develop communication, self advocacy, emotional awareness, decision making, resilience, and independence.
Through individualized ABA therapy, supportive family involvement, and consistent opportunities to practice, children can gradually build the skills they need to face unexpected situations with greater understanding and confidence.
