Most parents think carefully about what their child eats. Fewer think about how their child eats—and yet the mechanics of chewing are just as important to a child’s wellbeing as the nutritional content of their food. Chewing development in children follows a predictable sequence of milestones, and when that development is delayed or disrupted, the effects can ripple outward: into a child’s diet variety, their nutrition, their comfort at meals, and even their speech clarity.

At Autism Centers of Utah in Sandy, feeding therapists and occupational therapists work together to address chewing difficulties in children ages 2 through 12. Understanding how chewing normally develops—what to look for at each stage, what signs suggest something may be off, and what support is available—helps parents feel equipped to advocate for their child and act early when needed.

Understanding Chewing Development in Children

Chewing is not a single skill—it is the coordinated output of several overlapping systems: jaw strength and range of motion, tongue lateralization (the ability to move food sideways toward the back teeth), lip closure, sensory awareness of food in the mouth, and the cognitive ability to manage the chewing sequence without becoming overwhelmed. These systems mature gradually, from infancy through early childhood, and they develop together rather than in isolation.

Early chewing movements emerge as simple vertical motions—the jaw moves up and down, which works for soft, easily mashed foods. As the nervous system matures and children gain experience with varied food textures, the movement pattern becomes more sophisticated: the jaw begins to move in rotary, diagonal patterns that allow food to be ground effectively against the back teeth. This progression is what allows children to move from pureed foods to soft solids to firmer table foods over the first two years of life.

Chewing is also connected to sensory feedback. Children learn to regulate their chewing effort based on proprioceptive signals from the jaw muscles and tactile signals from the inside of the mouth. A child who does not receive clear sensory feedback may chew inconsistently, tire quickly, or stuff too much food into their mouth at once because they cannot clearly sense how much is already there.

Chewing Milestones by Age

Age Range Typical Chewing and Feeding Skills Foods Commonly Introduced
6–8 months Up-and-down jaw movements; beginning to manage soft lumps; tongue begins moving food side to side Mashed fruits, soft vegetables, smooth purees with small lumps
9–12 months Early diagonal jaw motion; improved tongue control; able to handle soft table foods Soft table foods, small pieces of pasta, soft-cooked vegetables
12–18 months More consistent rotary chewing; better bite control; beginning to chew firmer foods Chopped meats, cooked vegetables, soft fruits
18–24 months Stronger jaw strength; coordinated chewing on both sides; handles most table foods Mixed textures, firmer meats, most family table foods
2–5 years Refined rotary chewing; improved endurance; increasing independence with utensils Full range of age-appropriate table foods

These milestones are guides, not rigid standards—children develop at different rates, and some variation is normal. What is worth paying attention to is persistent delays that do not resolve, or patterns that suggest a child’s chewing development has stalled rather than progressed.

Signs a Child May Be Struggling with Chewing

Parents are often the first to notice when chewing development is not progressing smoothly, because they see their child eat multiple times every day. Signs that a chewing evaluation may be worthwhile include:

  • Food pocketing: Food collects in the cheeks rather than being chewed and swallowed. This often indicates that the tongue is not moving food efficiently toward the back teeth, or that the child cannot clearly sense how much food is in their mouth.
  • Gagging on age-appropriate textures: A child who gags frequently on foods that are appropriate for their age may have tactile hypersensitivity in the mouth or insufficient tongue coordination to manage those textures safely.
  • Strong preference for purees past toddlerhood: Many children naturally prefer softer textures, but a consistent refusal to transition to solid foods beyond age 2 or 3 may indicate that the chewing mechanics needed for those foods have not developed on schedule.
  • Fatigue during meals: If a child consistently leaves food partially chewed, asks to stop eating before finishing even small portions, or seems to tire during meals, inadequate jaw strength may be a contributing factor.
  • Chewing on one side only: Persistent unilateral chewing can indicate that the teeth, jaw muscle tone, or sensory tolerance on one side are less functional than the other.
  • Swallowing food whole: Children who skip chewing and swallow foods in large pieces may not be getting adequate sensory feedback from chewing, or may have learned to minimize the chewing experience because it feels uncomfortable.

The Role of Jaw Strength and Tongue Coordination

Jaw strength and tongue coordination are two of the most important physical components of chewing development, and both can be directly addressed through feeding therapy and occupational therapy.

Jaw strength determines how much force a child can generate to break down food. Children with reduced jaw strength may be able to chew soft foods but cannot manage firmer textures—cooked meats, raw vegetables, dense breads—without tiring. They may eat slowly, leave food on their plate, or accept only foods that require minimal chewing effort. Jaw strength builds naturally with practice on appropriately challenging textures, but children who avoid firm foods due to sensory sensitivity miss the practice opportunities needed to build that strength.

Tongue lateralization—the ability to move food sideways from the center of the mouth toward the back molars—is essential for effective chewing. Without adequate tongue lateralization, food stays in the front of the mouth where the jaw generates less crushing force, leading to insufficient chewing and increased swallowing risk. Tongue lateralization develops alongside other oral motor skills and can be targeted specifically through feeding therapy exercises that strengthen tongue movement in a gradual, playful way.

How Sensory Processing Affects Chewing Development

For children with sensory processing differences—which are common in autism—chewing development is often additionally complicated by how food textures and the chewing experience itself feel. A child with tactile hypersensitivity in the mouth may find the sensation of chewing certain textures genuinely overwhelming. Crunchy foods may feel too loud or too intense. Mixed textures may be confusing because they produce inconsistent sensory feedback with each bite. Lumpy or fibrous foods may feel alarming rather than manageable.

These sensory responses directly limit the practice opportunities children need to build chewing skills. A child who only tolerates smooth purees will not develop the rotary chewing pattern needed for solid foods, because they are never practicing it. A child who only eats crunchy foods will build jaw strength for that texture class but may struggle to apply chewing skills to softer foods because they have never had cause to do so.

This is why feeding therapy and occupational therapy often work in tandem on chewing challenges in children with autism. The occupational therapist addresses the broader sensory processing and regulation issues, helping the child build tolerance for tactile input and manage sensory overload. The feeding therapist then uses that increased tolerance as a foundation for structured chewing practice across a gradually expanding range of textures.

How Feeding Therapy and OT Address Chewing at Autism Centers of Utah

At Autism Centers of Utah, feeding therapy and occupational therapy share a building, communicate daily, and coordinate their approaches for each child. When a child is working on chewing development, the two therapists align their goals so that OT work on sensory desensitization directly supports the texture expansion goals in feeding therapy.

In feeding therapy, chewing work is always child-led and never forced. Therapists use a food texture hierarchy—organizing foods from least to most challenging based on the specific properties that are difficult for the child—and work through it systematically, building genuine tolerance at each level before advancing. Oral motor exercises are incorporated into sessions using food-safe tools and playful activities that strengthen jaw muscles, improve tongue coordination, and build proprioceptive awareness in the mouth.

For children with autism who have sensory-based chewing difficulties, therapists also use non-food sensory tools—vibration tools, textured chewables—to provide oral sensory input that helps calibrate the nervous system’s response to oral stimulation. Over time, this kind of systematic sensory input can reduce the hypersensitivity that makes chewing new textures feel overwhelming.

Families from South Jordan and the surrounding area who bring their children to Autism Centers of Utah often report that the coordination between therapists is one of the most valuable aspects of the program. Rather than managing two separate providers with separate agendas, they have a team that understands the full picture of their child’s chewing challenges and is working toward the same goals.

How Chewing Connects to Speech Development

An aspect of chewing development that surprises many parents is its connection to speech clarity. Chewing and speech share many of the same muscle groups—the jaw, lips, and tongue are used in both activities, and the coordination patterns developed through chewing contribute to the oral motor skills needed for clear articulation.

Children who have limited practice with varied chewing movements may show reduced awareness and control of their jaw, lip, and tongue movements—the same movements needed to produce speech sounds accurately. This is one reason why oral motor development in the context of feeding is relevant not just to nutrition and mealtime success but to the broader developmental picture. Addressing chewing difficulties early supports multiple developmental domains simultaneously.

Supporting Chewing at Home

Parents can support chewing development through simple, consistent practices at home that complement what happens in therapy. Some of the most effective include:

  • Offer foods at the child’s current skill level while consistently including one slightly more challenging option nearby—without pressure to eat it
  • Sit together at meals and model chewing, which gives children a visual reference for the chewing pattern
  • Allow adequate time for meals so children do not feel rushed, which reduces the tendency to swallow food whole
  • Cut foods into manageable pieces appropriate for the child’s current skill level—too large increases choking risk; too small eliminates the chewing practice
  • Avoid distractions during meals (screens, loud background noise) that draw attention away from the sensory experience of chewing

Frequently Asked Questions

What age should children start chewing solid foods?

Most children begin early up-and-down chewing motions around 6 to 8 months with soft foods, gradually developing rotary chewing patterns between 9 and 18 months as their oral motor skills mature.

Is it normal for my child to still prefer soft foods at age 3 or 4?

Temporary texture preferences are common, but a persistent preference for pureed or very soft foods at age 3 or 4 may indicate that chewing development has stalled. A feeding therapy evaluation can help determine whether intervention is appropriate.

How does jaw strength affect eating long-term?

Insufficient jaw strength limits the range of foods a child can eat comfortably and may lead to nutritional gaps as certain food categories—proteins, many vegetables—require more chewing force. Building jaw strength through feeding therapy expands the child’s accessible diet significantly.

Can chewing difficulties in autism be fully resolved?

Many children with autism who receive targeted feeding therapy and OT support make meaningful progress with chewing—expanding their texture tolerance and developing more effective chewing mechanics. The goal is not perfection but a functional range of foods that supports good nutrition and comfortable participation in meals.
