Quick answer. Oral motor skills develop in a predictable order — reflexive suckling, then voluntary sucking, then munching, then true rotary chewing — with each skill building on the one before.1 The most effective way to support that sequence is not exercises or gadgets. It is giving a child the right food textures at roughly the right time, in a well-supported seated position, without pressure. The tools marketed as “oral motor development” products mostly do something more modest than their labels claim.

Key Takeaways

  • Oral motor development follows a feeding sequence, not a cognitive one. Suckling, sucking, munching, rotary chewing — each stage building on the last.1
  • Feeding and speech share the same structures on different timelines. Progress in one does not guarantee progress in the other, but difficulties in both often appear together.
  • Texture progression is the highest-value thing to track. Late introduction of lumpy foods is associated with feeding difficulties still measurable at age seven.4
  • Position matters more than most parents expect. Feet supported, hips at 90 degrees. A child bracing against gravity has less control left for their mouth.
  • Most “oral motor” products do less than claimed. Teethers are fine for teething comfort and safe mouthing. They are not a developmental intervention, and no good evidence supports blowing toys, horns or straws-as-therapy.7,8
  • Skill loss is the signal that matters most. A child who could chew and now cannot needs assessment, not monitoring.

How oral motor skills actually develop

A correction to what this page used to say. The previous version listed the stages of oral motor development as “reflexive, primary circular reactions, secondary circular reactions, symbolic thought”. Those are Piaget’s stages of cognitive development. They describe how a child comes to understand the world, not how a mouth learns to chew, and they gave a parent trying to check whether their child was on track entirely the wrong ladder. What follows is the sequence a speech-language pathologist or feeding specialist actually works from.

Feeding and swallowing development is a complex set of interactions that begins in the embryonic and fetal periods and continues through infancy and early childhood.1 Sucking and swallowing are underway before birth, well before a baby ever needs them.

AgeOral motor skillWhat it looks like
Birth to 3 monthsReflexive suckling; suck-swallow-breathe coordinationRhythmic front-to-back tongue motion; the tongue extrusion reflex pushes solids out — normal and expected
3 to 6 monthsTransition to voluntary sucking; extrusion reflex fading; hands to mouthMore up-and-down tongue motion; mouthing hands and toys; first spoon acceptance around 6 months as head and trunk control arrive
6 to 9 monthsMunching begins; tongue starts lateral movement; first cup sipsSimple up-and-down jaw motion on soft solids; food moved side to side with the tongue; accepts thicker textures
9 to 12 monthsEarly rotary chewing; lumpy and mashed textures; finger foodsJaw begins a diagonal, grinding motion; self-feeds pieces; cup drinking improving
12 to 18 monthsRotary chewing established; open cup; spoon with helpHandles most soft table foods; chews in a circular pattern rather than only up and down
18 to 24 monthsStraw drinking; more efficient chewing; utensil use improvingEats a version of family food; some mess still expected
2 to 3 yearsChewing of mixed textures; mature swallow developingManages raw vegetables, meat, and foods with more than one texture in a bite

Ranges overlap widely. Watch the sequence, not the dates.

Munching is not chewing. Munching is a simple up-and-down jaw movement. Rotary chewing is a diagonal grinding motion that handles meat and raw vegetables, and it arrives considerably later and keeps maturing well into the second year. Parents often report that a child “chews” when what they are seeing is munching — which is fine at nine months and a flag at two.

The sequence matters more than the calendar. A child three months behind but steadily moving through the stages usually needs time. A child stuck at the same stage for six months needs a look.

Losing a skill is a different question entirely. A child who chewed and now will not is not a slow developer; that is a call to your pediatrician.

Our companion page on spotting oral development delays early covers the warning signs in more detail, and the role of oral reflexes covers the reflexive starting point of the sequence.

Why feeding and speech travel together

The lips, tongue, jaw, palate and breath support that let a child manage a piece of chicken are the same structures that let them produce a /k/. Both jobs are being learned at once, on different schedules.

This is why feeding and speech difficulties frequently co-occur — but the relationship is looser than it sounds. Plenty of children chew beautifully and say “wabbit” for years. Plenty of others speak clearly and gag on anything lumpy. Do not use one as a proxy for the other.

On the speech side, the current normative review of 18,907 American children puts acquisition later than most charts suggest. Most consonants are acquired by five years, and at the 90% criterion all plosives, nasals and glides are in place by 3 years 11 months, all affricates by 4 years 11 months, all liquids by 5 years 11 months, and all fricatives by 6 years 11 months.2 Our page on speech and language milestones from birth to seven covers the parallel track, and delayed speech covers when to act.

What actually helps, stage by stage

Birth to 6 months — protect the basics

There is not much to promote here. A term baby arrives with the suck-swallow-breathe pattern already coordinated. What helps is responsive feeding, unhurried feeds, and letting the baby mouth their hands and safe objects — early mouthing is exploration, and it is how the mouth gathers information.

If feeding is painful, ineffective, or the baby is not gaining, that is a lactation and pediatric question rather than a developmental one, and it deserves prompt attention rather than wait-and-see.

6 to 9 months — the texture window

This is where parents have the most leverage, and it is the part most parenting content skips.

Two large studies from the same UK birth cohort tracked when children were first given lumpy solids. In the first, of 9,360 infants, 10.7% were introduced before 6 months, 71.7% between 6 and 9 months, and 17.6% after 10 months. At both 6 and 15 months, those introduced late were more difficult to feed and had more definite likes and dislikes, and at 15 months were significantly less likely to be eating family foods.3

The follow-up tracked 7,821 children to age seven and found late introduction associated with a greater incidence of feeding problems at 15 months — picky eating, being difficult to feed, prolonged consumption of baby foods — and reduced food acceptance still measurable at seven years.4

  1. Offer soft lumps and mashed textures alongside purees rather than staying smooth until the child seems ready.
  2. Expect gagging. Gagging is a protective reflex and part of learning, not a sign to retreat. Choking — silent, with distress and no sound — is different, and is an emergency.
  3. If your child is nearing 10 months and still on purees only, raise it at the next visit. Not as an emergency; as the single most useful thing on your list.

9 to 18 months — build the chew

  • Offer foods that require real chewing, cut safely for age: soft-cooked vegetable sticks, strips of meat, bread with crust, whole soft fruit.
  • Let them self-feed. Hand-to-mouth work builds the motor plan and gives the child control over pace, which matters more than tidiness.
  • Alternate textures within a meal rather than serving one consistency throughout.
  • Move to an open cup and a straw rather than staying on a spouted cup indefinitely — different lip and tongue patterns.

18 months to 3 years — consolidate

  • Serve family food, modified rather than separate.
  • Keep offering rejected foods without pressure. Repeated neutral exposure is the mechanism that works.
  • Protect the seating. Feet supported, hips at 90 degrees, table at elbow height. A child dangling from a chair is spending postural effort they need for their mouth. This is the cheapest and most under-used intervention on the page.
  • Keep mealtimes low pressure. Pressure to eat is among the feeding practices associated with worse outcomes, and it is the first thing most families reach for.

Tools and products, honestly rated

The previous version of this page recommended several products with claims that do not hold up. Here is the honest version.

ProductVerdictWhat the evidence actually says
Graded food textures, self-feeding, supported seatingSupportedTask-specific practice is what motor learning principles predict will transfer. If the goal is chewing, the practice that works is chewing.
TeethersReasonable, untestedSafe to mouth, genuinely soothing during teething, and mouthing is part of normal oral exploration. No evidence that a teether accelerates oral motor development.
Mesh and silicone fresh-food feedersReasonable, untestedUseful for experiencing flavors and cold safely. Not a developmental intervention. Put fruit and vegetables in it rather than anything sweetened.
Gum stimulatorsNo good evidenceThe same category as teethers, marketed with more clinical-sounding language and no better support.
Pacifiers as a development toolNo good evidencePacifiers have real benefits in infancy, but jaw development is not one. Prolonged habits carry a higher risk than digit sucking for posterior crossbite (OR 2.66),5 and risk is duration-dependent.6
Blowing toys, horns, whistles, straws-as-exercise, lip massageNo good evidenceThe Cochrane review found three studies with 22 children in total and insufficient evidence to draw conclusions.7

Why the blowing exercises do not work, beyond the thin evidence. The theoretical objection is the stronger one. Training non-speech oral motor tasks is not supported by current principles of motor learning and neural plasticity, which favor experience-specific training, and functional imaging shows different activation patterns for speech compared with non-speech oral motor tasks.8 Blowing a horn is practice at blowing a horn.

Our DrParenting article on what the evidence says about pacifiers covers the benefits side properly, and when thumb sucking is a problem covers the timelines.

When to get help

Contact your pediatrician promptly for

  • Coughing, choking or gagging during or just after feeds, especially with liquids
  • A wet or gurgly-sounding voice after eating or drinking
  • Recurrent chest infections or unexplained wheezing
  • Nasal regurgitation
  • Poor weight gain alongside feeding difficulty
  • Any loss of a previously established skill

Request an evaluation for:

  • Still on smooth purees only approaching 10 months
  • No rotary chewing by around two years
  • A diet that is shrinking rather than slowly widening
  • Meals that routinely take over 30 minutes or exhaust the child
  • Speech unfamiliar adults cannot follow at four and beyond

Where difficulty is severe enough to affect nutrition, growth or family functioning, the relevant framework is pediatric feeding disorder — a formal consensus-defined diagnosis with a multidisciplinary pathway, not a phase to wait out.9

How to get seen. A speech-language pathologist is the primary evaluator for feeding, swallowing and chewing skills; an occupational therapist where sensory tolerance is the limiting factor. For children under three you can refer directly to your state’s early intervention program without a physician referral, and the evaluation is free — our page on spotting oral development delays early walks through that process. You can also browse providers by state.

Where sensory sensitivity is driving texture refusal rather than motor skill, our overview of sensory processing differences in children and sensory seeking behaviors are the better starting points.

Frequently Asked Questions

What are the stages of oral motor development?

Feeding and swallowing development follows a sequence: reflexive suckling and suck-swallow-breathe coordination from birth, a shift to voluntary sucking over the first months, spoon acceptance and first purees around six months as head and trunk control arrive, munching from roughly six to nine months, and rotary chewing developing from around nine months and maturing well into the second year.1 Note: the stages previously listed on this page — reflexive, primary and secondary circular reactions, symbolic thought — are Piaget’s stages of cognitive development, not a description of oral motor skills.

What is the difference between munching and chewing?

Munching is a simple up-and-down jaw movement that appears around six to nine months and handles soft solids. Rotary chewing is a diagonal, grinding motion that manages meat and raw vegetables; it develops later and continues maturing into the second year. A child who “chews” at nine months is usually munching, which is on track. A two-year-old still only munching is worth mentioning.

Do teethers and gum stimulators help with oral motor development?

Not in the way the labels suggest. They are safe to mouth and genuinely soothing during teething, and mouthing is a normal part of oral exploration. But there is no good evidence that either accelerates oral motor development. Use one because your baby finds it comforting, not as an intervention.

Do blowing toys, horns or straw exercises improve speech or chewing?

No. A Cochrane review of non-speech oral motor treatment found three studies with 22 children in total and insufficient evidence to draw conclusions.7 Training non-speech oral tasks is also not supported by principles of motor learning, which favor task-specific practice, and imaging shows different brain activation for speech versus non-speech oral tasks.8 If the goal is chewing, chewing is the practice that transfers.

When should my baby start lumpy foods?

Most children make the move between six and nine months — in a study of 9,360 infants, 71.7% were introduced in that window.3 Children introduced after 10 months were more difficult to feed and had more definite likes and dislikes, and a follow-up of 7,821 children found late introduction associated with feeding problems at 15 months and reduced food acceptance still measurable at seven years.4

My baby gags on lumpy food. Should I go back to purees?

Gagging is a protective reflex and part of learning to manage texture — retreating to smooth is the response most likely to entrench the problem. Choking is different: silent, with distress and no sound, and it is an emergency. If gagging is frequent and distressing, a feeding therapist can grade the progression so it stays tolerable.

Does a pacifier help jaw development?

No. Pacifiers have real benefits in infancy, but none of them is jaw development. Prolonged pacifier habits carry a significantly higher risk than digit sucking for posterior crossbite, with an odds ratio of 2.66,5 and the risk is duration-dependent.6 Any pacifier marketed as promoting proper jaw development is making a claim the evidence does not support.

Do feeding skills predict speech skills?

They share structures but not schedules. Difficulties often co-occur, but plenty of children chew well and articulate poorly, or the reverse. Assess whichever one is the actual concern rather than inferring from the other.

When should I worry about my child’s oral motor skills?

Promptly for coughing or choking during feeds, a wet-sounding voice after swallowing, recurrent chest infections, or any loss of a previously established skill. On a normal timeline for a child still on purees only near 10 months, no rotary chewing by around two, a shrinking diet, or meals that routinely exhaust the child.

Does oral hygiene affect my child’s ability to eat and speak?

Indirectly and importantly. Untreated decay causes pain that changes how a child chews and what they will accept. Brushing twice daily with fluoride toothpaste from the first tooth, and a first dental visit by age one, is the practical version. Our page on brushing from a very young age covers the routine.
