In my opinion, three major factors play a critical role in the early trajectory of airway growth and development:
- Breastfeeding for as long as the parent and child are safely able
- Appropriate, developmentally guided progression into textured foods
- Regular chewing as the child grows
When these developmental opportunities are disrupted during the first years of life, children may lose some of the functional stimulus that supports oral coordination and development.
Even when families do everything “right,” there are no guarantees. The goal is not perfection. The goal is to provide a healthier developmental starting point when circumstances allow.
Infant feeding, breastfeeding, food texture, choking risk, swallowing concerns, pacifier use, and bottle selection should be discussed with the child’s pediatrician and appropriately trained feeding, lactation, dental, or myofunctional professionals. This article is educational and should not be used as individualized feeding or medical advice.
Breastfeeding and Early Oral Function
A child’s palate is highly adaptable during early development. Breastfeeding provides repeated opportunities to coordinate the tongue, lips, cheeks, swallowing muscles, breathing, and oral pressure.
During breastfeeding, the tongue interacts with the palate while the lips help maintain a seal. Greg describes this repeated coordination as the child’s earliest form of oral training.
The child receives a high volume of practice coordinating suction, swallowing, tongue movement, lip seal, and nasal breathing.
Greg compares this repetition to an athlete practicing the same movement over and over. Volume matters because repeated movement helps the nervous system develop familiar motor patterns.
“The Spot”
Greg uses “the spot” to describe the area of the palate where the tongue ideally rests.
He describes the tongue as providing internal support to the upper dental arch while participating in pressure regulation, swallowing, and nasal-breathing mechanics.
When the lips close and the tongue works with the palate during feeding, the child practices creating and regulating pressure within the mouth.
Greg believes these early repetitions can influence the developmental trajectory of the oral cavity, facial muscles, swallowing pattern, and breathing behavior.
The Bellows Effect
Greg uses the term “bellows effect” as an analogy for the relationship between the tongue, palate, cheeks, nose, inhalation, and exhalation.
In this analogy, coordinated oral pressure and nasal airflow behave somewhat like the bellows historically used to move air into a fire.
The larger idea is that breathing mechanics, oral posture, facial-muscle coordination, and pressure regulation function as parts of one connected system.
The bellows effect is Greg’s educational analogy; it is not an established diagnostic or medical mechanism.
Not every parent can or should breastfeed, and breastfeeding outcomes can be affected by anatomy, milk supply, health conditions, medication, maternal recovery, infant health, access to support, and many other factors.
This discussion is not intended to shame parents or suggest that breastfeeding guarantees a particular developmental outcome.
Progressing Into Textured Foods
Greg’s second major factor is how children progress from milk feeding into increasingly textured food.
After listening to clinicians and specialists working in airway development, pediatric feeding, dentistry, and myofunctional therapy, Greg became interested in the idea that food texture and oral challenge may matter alongside nutritional quality.
He describes this principle using the phrase:
“Stop the slop.”
“Stop the slop” is Greg’s informal wording—not a recommendation to ignore feeding readiness or professional guidance.
Greg’s concern is that an exclusively soft modern diet may provide less chewing, gnawing, muscular effort, and functional challenge than developing oral structures historically experienced.
Muscles and bones respond to appropriate use and mechanical demand. Food texture can also provide opportunities to practice coordination.
However, feeding development is individual. Texture progression must account for developmental readiness, swallowing ability, allergies, sensory needs, neuromuscular conditions, medical history, and choking risk.
Progress, Not Perfection
Parents often feel pressure to find one perfect feeding method.
Greg’s larger point is not that every family must follow the same protocol. It is that parents should understand why chewing, oral coordination, and texture progression deserve thoughtful attention.
Advice may differ depending on the child, the clinician, the feeding philosophy, cultural practices, and the family’s circumstances.
Parents should create an informed approach with their child’s care team, remain open to changing that approach, and avoid allowing the pursuit of perfection to create unnecessary fear.
Cups, Bottles, and Pacifiers
Greg’s source material includes professional opinions about open cups, straw cups, sippy cups, bottles, nipple flow, and pacifier shape.
Professionals may make different recommendations about cups, bottles, nipple flow, and pacifiers depending on a child’s age, oral function, airway, feeding skills, medical history, and developmental needs.
Long-term dependence and the way an item affects tongue movement or oral posture may be more important than treating every item as universally good or bad.
Some children with medical or anatomical complications may receive recommendations that differ from general guidance.
Families with questions should consult their pediatrician, lactation professional, pediatric feeding specialist, speech-language pathologist, dentist, or orofacial myofunctional professional.
A Note From Greg
“This field is not my specialty. Parents with feeding, swallowing, bottle, cup, or pacifier questions should work with qualified specialists who can assess their individual child.”
Chewing and Developmental Work
Something I had not considered until studying anthropology and craniofacial development was how much less many people chew today.
Modern foods are frequently softer, more processed, and easier to consume than the foods eaten by previous generations.
Greg believes this reduces the daily mechanical workload placed upon the jaws and surrounding muscles.
He compares adequate chewing to getting 10,000 steps a day.
The comparison is not about reaching a literal universal number. It represents the repeated daily work that developing tissues historically experienced through chewing.
Why Mechanical Work Matters
Bones and muscles respond to appropriate stimulus.
Chewing provides mechanical strain, muscle activity, coordination practice, and repeated loading of the jaws and dental arches.
The size and shape of the teeth and tongue are influenced by genetics, while the development of the surrounding structures is also affected by growth, function, health, nutrition, environment, habits, and other factors.
Greg’s central question is whether modern children receive enough appropriate chewing and oral work to support the structures being asked to house the teeth, tongue, and airway.
The Larger Lesson
The point is not that parents should force extremely hard food, ignore readiness, or deliberately create a choking risk.
The point is that oral development requires appropriate opportunities to work.
Parents can discuss age-appropriate food textures and chewing opportunities with qualified professionals, especially when a child has a history of feeding difficulty, coughing, choking, restricted food acceptance, oral-motor concerns, delayed progression, tongue restriction, craniofacial differences, or airway symptoms.
Greg’s three-factor model is ultimately about recognizing that development is active.
Breathing, feeding, swallowing, chewing, tongue posture, facial-muscle coordination, and jaw growth do not occur in isolation.
The goal is not to frighten parents or demand perfection. It is to help families recognize that the everyday activities occurring during early childhood may influence a much larger developmental picture—and that informed professional support can help families make safer, clearer decisions.
