“Have a holly jolly Christmas
And when you walk down the street
Say hello to friends you know.
And everyone you meet.”
The lyric undoubtedly captures the warmth and joy of the season. For a child with a uniquely wired brain, however, December can feel far less magical and far more overwhelming.
It is often the busiest month of the year, filled with unspoken social expectations that can be especially hard for autistic children and children with ADHD to understand and manage. What feels natural and festive to many adults can feel confusing, intense, and relentless to a neurodivergent nervous system.
Suddenly, familiar people show up in places you do not expect. The doctor with zoo animal stickers, the physiotherapist who gives big high-fives, and the teaching assistant who plays with you at school. Even your teacher, who feels like a hero, is now in a crowded shop, smiling and asking how you are. They are the same people, but somehow, they feel different.
Everything feels different, and it all happens at once.
Mommy and Daddy look very busy. They keep asking what I want for Christmas. But I really do not know for sure, because there is so much going on around me that I do not fully understand. Shops are loud. Everyone seems excited, but the rules are not clear to me.
Can I have my calm, routine, and familiar space back, please?
December Is Not One Stressor, but Many
From a neurodevelopmental point of view, December is not defined by a single difficult event. It is a month of ongoing, cumulative demands.
Both autistic children and those with ADHD often rely on predictable routines to stay regulated. When routines disappear and uncertainty increases, their brains must work significantly harder to interpret what is happening and what is expected of them.
When demands remain high for extended periods, the nervous system can stay in a constant state of alert. Therefore, what looks like “difficulty coping with Christmas” is often the result of accumulated stress, not a lack of flexibility or ability.
Social Interest and Social Capacity Are Not the Same Thing
Social interaction requires substantial cognitive effort. It involves using language, reading facial expressions and tone of voice, recalling people and past interactions, understanding context, and predicting what might happen next, all at the same time.
For children with ADHD, this effort is even greater due to differences in attention regulation, working memory, and impulse control.
On the other hand, there is a persistent myth that autistic individuals are not interested in social connections. However, research consistently shows that many autistic children want to connect, but they process social information differently, particularly under stress.
As demands rise throughout December, social energy naturally declines, even when the desire to connect remains. Reduced participation, withdrawal, or irritability are therefore noticeable signs of overload, not indicators of disinterest.
When Familiar People Appear in Unexpected Places
For many autistic children, social understanding is highly dependent on context. People are often linked to specific roles and environments.
A teacher at school follows one set of social rules. Seeing the same teacher in a crowded shop requires a rapid shift to a different set of expectations. In December, these boundaries blur frequently.
When familiar people appear in unexpected places, children must quickly determine which rules apply, how to greet the person, how long to interact, and how friendly to be. When this information is unclear, anxiety increases.
This may come in the form of a blank stare, avoiding eye contact, or pulling away. The issue is not unwillingness to connect, but uncertainty about how to do so “correctly.”
Sensory Overload and the Brain
Christmas environments are rich in sensory input: loud music, crowds, bright lights, unfamiliar smells, and constant movement. One truth that is being repeatedly backed by evidence is that the differences in sensory processing are a core feature of autism and are also common in ADHD.
When sensory input exceeds what the nervous system can manage, regulation becomes harder. As a result, communication, emotional control, and attention can all decline at once.
For autistic children, sensory overload may lead to withdrawal, shutdown, or meltdowns. For children with ADHD, the same overload often appears as increased movement, impulsivity, or seeming hyperactivity, which are ways the brain attempts to regulate high arousal.
When these coping strategies are no longer sufficient, emotional outbursts or meltdowns signal that the system has reached its limit.
The Hidden Cost of “Being Festive”
December often carries strong social expectations to be polite, grateful, affectionate, and cheerful.
Unstructured social gatherings require sustained attention to unwritten rules at a time when overall capacity is already reduced.
Family events can be especially demanding, particularly for autistic girls, who often mask more intensively and are known to succeed in doing so due to social pressure and fear of judgment.
Masking, which means hiding signs of distress to fit in, may look successful in the moment, but it requires significant mental effort and often leads to exhaustion afterwards.
For children with Autism, ADHD, or both, this creates pressure to perform socially while suppressing genuine discomfort.
Long-term research links sustained masking and chronic stress to increased anxiety, depression, and burnout, making us rethink the expectations we hold onto as a society.
What Actually Helps During High-Demand Periods
Support during December is most effective when it reduces stress rather than adding new expectations.
Helpful approaches include:
- Increasing predictability through clear explanations and preparation
- Reducing social demands during periods of sensory overload
- Allowing autonomy around greetings, physical contact, and participation
- Providing access to quiet, familiar spaces
- Supporting regulation through calm, emotionally attuned adults
Practical adjustments matter the most. Christmas shopping, for example, can be overwhelming, but online shopping, visiting at quieter times, or keeping trips brief can significantly lower stress.
Tools such as Social Stories are most effective when they explain routines and sensory experiences rather than attempting to enforce social performance. Their value lies in predictability, not compliance.
Educators, parents, and caregivers act as essential buffers. They model, explain, scaffold, and set boundaries. While generalisation of social skills is important as we all agree, it is equally important not to stretch children beyond their regulatory capacity, particularly in high-demand moments.
Rethinking What “Inclusion” Looks Like
For an autistic child or a child with ADHD, a successful December may look quieter, shorter, and less socially intense than traditional celebrations.
Strategies such as offering reassurance, leaving early, skipping events, using headphones, moving freely, or staying close to trusted adults are not developmental setbacks. They are adaptive supports that promote genuine participation.
When success is measured by emotional safety rather than social performance, holidays become more inclusive and truly joyful.
For many families, recognising this is less about doing more and more about letting go of expectations that no longer serve their child’s well-being.
Therefore, understanding the why behind what we see will guide us to respond with empathy, flexibility, and informed accommodation.
Evidence Note
This reflection is informed by established peer-reviewed research on neurodevelopment, including work on executive functioning and self-regulation in ADHD (Barkley, 2015; American Psychiatric Association, 2022), social motivation and participatory experiences in autistic children (Pellicano et al., 2022), sensory processing differences (Dunn, 2014), and the cognitive and emotional costs of masking (Hull et al., 2020; Cage & Troxell-Whitman, 2019). These sources reflect well-replicated findings and contemporary clinical consensus, and are included to support clarity, context, and neuro-affirming interpretation rather than exhaustive review.
