Episode 257: What's the link? Oral function, sleep quality and ADHD with Tash Duffin from Whole Child Co

Key takeaways

Poor sleep quality can significantly mimic or worsen ADHD-like behaviors in children, affecting their focus, impulse control, and emotional regulation.
Airway health and proper oral function are vital for children’s overall development and behavior; issues like mouth breathing and sleep-disordered breathing need early attention.
Parents should observe their children for signs of airway or sleep issues, including restless sleep, open-mouth breathing, snoring, bedwetting, dry lips, and picky eating.
Seeking support from qualified health professionals is crucial for accurate assessment and targeted intervention, rather than dismissing concerns or relying solely on medical surgery.
Addressing root causes—such as congestion, enlarged tonsils, or poor oral habits—can significantly improve sleep quality and reduce ADHD-like symptoms in kids.
Proactive, holistic management involving lifestyle changes, exercises, and specialist therapies can lead to better health and developmental outcomes.
Advocacy and early intervention are key to preventing long-term issues; parents should trust their observations and pursue appropriate evaluations.

Summary

Introduction to the Connection Between Child Health, Sleep, and Immune Function

This section introduces the common struggles families face during winter with recurring illnesses in children, highlighting the cycle of viruses and the impact on family life. The host promotes a free masterclass aimed at explaining why children get sick frequently and what parents can do to strengthen their child's immune system. Key topics include understanding the four areas where parental habits may unintentionally weaken immunity, the importance of natural tools and strategies, and dispelling myths around fever management. The focus is on practical, accessible information to help parents support their children's health more effectively.

Expert Introduction and Personal Experience with Pediatric Health Challenges

Jessica Donnegan introduces Tash Duffin, an occupational therapist and orofacial myofunctional therapist, who also works in pediatric sleep, feeding, and reflux. Tash shares her personal journey as a mother of three, with children experiencing oral dysfunction, sleep disturbances, and one diagnosed with ADHD. Her professional and personal insights provide a comprehensive perspective on children's health issues, emphasizing the interconnectedness of oral function, sleep, and developmental outcomes.

The Link Between Sleep Quality and ADHD-Like Behaviors

This section explores the significant overlap between poor sleep quality and ADHD-like behaviors in children. Research shows that inadequate or fragmented sleep can cause or exacerbate symptoms such as inattention, impulsivity, hyperactivity, and emotional dysregulation. The discussion details how sleep disruptions affect the prefrontal cortex's function, leading to behavioral issues that mimic or worsen ADHD. The conversation underscores the importance of deep, restorative sleep for brain health and behavior regulation.

Airway Health, Mouth Breathing, and Their Impact on Child Development

The episode emphasizes the crucial role of airway health and oral function in children's development. Issues such as mouth breathing, sleep-disordered breathing, and upper airway resistance can negatively influence sleep quality, behavior, and neurological health. Signs of airway issues include open-mouth sleeping, restless sleep, unusual sleep positions, bedwetting, dry lips, bad breath, picky eating, and daytime fatigue. The importance of early intervention, proper assessment, and working with specialists to address airway obstructions or dysfunctions is stressed to prevent long-term developmental and behavioral problems.

Parental Guidance on Recognizing and Addressing Sleep and Oral Function Issues

Parents are encouraged to observe their child's sleep environment and behaviors, noting signs like loud snoring, open-mouth breathing, restless sleep, and unusual postures. The importance of capturing photos or videos for professional assessments is highlighted. The episode advises seeking support from qualified practitioners like GPs, ENT specialists, orofacial therapists, and sleep experts to investigate underlying causes. It also discusses practical strategies such as improving nasal breathing through gentle exercises, managing congestion, reducing reliance on dummies, and promoting healthy oral habits. The importance of advocating for children's health and understanding that solutions often involve addressing root causes rather than quick fixes is reinforced.

Holistic Approaches and the Role of Therapies in Managing Oral and Airway Issues

The episode advocates for comprehensive, individualized interventions for children with airway and oral function concerns. Working with specialists like orofacial myofunctional therapists is essential to identify the causes of mouth breathing and develop targeted treatment plans. Examples include improving tongue-to-palate contact, encouraging nose breathing, and gradually reducing habits like thumb-sucking or dummy use. The importance of addressing underlying issues such as congestion, allergies, or enlarged tonsils is stressed. While surgical interventions may be necessary in some cases, the focus remains on correcting functional and developmental factors to support long-term health.

Advocacy and Resources for Parents

Parents are encouraged to advocate for their children’s health by persistently seeking proper assessments and interventions. The episode stresses that early recognition and intervention can have a profound impact on a child's development, behavior, and sleep quality. Resources include professional support from sleep and oral health specialists, and the host's upcoming offerings like online consultations and a membership program to support ongoing management. The goal is to empower parents with knowledge and practical tools to foster better health outcomes for their children.

The Link Between Oral Function, Sleep Quality and ADHD in Children

This week on the podcast, we’re exploring a fascinating and important connection that more families need to know about: the link between oral function, sleep quality, and ADHD-like behaviours in children.

We are joined by Tash Duffin from Whole Child Co, an occupational therapist, orofacial myofunctional therapist, and practitioner working in infant and early childhood sleep quality, feeding, and reflux. Tash also brings her own lived experience as a mum, which makes this conversation feel both deeply informed and incredibly practical.

Together, they unpack how poor sleep quality, mouth breathing, and airway dysfunction can influence focus, impulsivity, emotional regulation, behaviour, and overall development. This episode is especially valuable for parents of children with an ADHD diagnosis, ADHD-like symptoms, restless sleep, mouth breathing, or ongoing feeding challenges.

In this episode, we discuss:

How poor sleep quality can mimic or worsen ADHD-like behaviours, including the impact of fragmented sleep on focus, impulsivity, emotional regulation, and hyperactivity.
Why airway health and oral function matter so much, and how mouth breathing, sleep-disordered breathing, and poor oral rest posture can affect a child’s development, behaviour, and nervous system regulation.
The signs that may point to underlying sleep and airway issues, including open-mouth sleeping, restless sleep, unusual sleeping positions, bedwetting, grinding, dry lips, bad breath, selective eating, and daytime fatigue.
Where parents can start if they’re concerned, from observing their child’s sleep more closely to seeking the right support and understanding why addressing root causes matters more than relying on quick fixes alone.

🎧 Tune in to learn more about the connection between oral function, sleep quality, and ADHD, and why looking more closely at how your child breathes and sleeps may offer an important missing piece in their overall health and behaviour picture.
