Olfactory & Gustatory Integration

Smell Processing ยท Taste ยท Oral-Motor Function ยท Food Acceptance. Olfaction has direct connections to the limbic (emotional) brain, bypassing the thalamus โ€” making smell the most emotionally charged sense.

โšก Gustatory (taste) processing is tightly linked to touch receptors inside the mouth โ€” oral texture is inseparable from taste in children with tactile sensitivity. Both must be addressed together.

Olfactory Exploration Kit
6.1
โ˜… Easyโฑ 10โ€“15 min
๐ŸŽฏ Build olfactory discrimination; provide structured smell-seeking outlet; reduce indiscriminate sniffing
  1. Prepare 8โ€“10 small jars or cotton-wool balls soaked in scents: vanilla, lavender, peppermint, cinnamon, lemon, rose, coffee, pine
  2. Child sniffs each jar (1โ€“2 seconds) and rates: 'love / like / neutral / dislike / hate'
  3. Scent matching: prepare duplicate jars โ€” child matches pairs with eyes closed
  4. Scent sequencing: child smells 3 jars in order; adult changes order โ€” child re-identifies the sequence
  5. Scent storytelling: 'this smell reminds me ofโ€ฆ' โ€” builds language around olfactory experience
  6. Child selects 3 favourite scents to use as personal calming tools
๐Ÿ’ก TipsUse preferred scents in a personal inhaler stick โ€” child carries to sniff instead of sniffing people. Introduce challenging scents at very low intensity โ€” dilute in carrier oil first.
SOS Feeding Hierarchy
6.2
โ˜…โ˜…โ˜… Advancedโฑ 20โ€“30 min ยท weekly (SLP/OT)
๐ŸŽฏ Expand accepted foods in extreme food selectivity; reduce oral tactile avoidance
  1. Stage 1 โ€” Tolerate: food is present on the table; no expectation to touch it
  2. Stage 2 โ€” Interact: child touches the food with a utensil; moves it around the plate
  3. Stage 3 โ€” Smell: child brings food near nose and sniffs it
  4. Stage 4 โ€” Kiss: child touches food to lips only โ€” no tasting
  5. Stage 5 โ€” Lick: child licks surface of food โ€” spit-out allowed
  6. Stage 6 โ€” Bite & spit: small bite, child spits out. Stage 7 โ€” Chew & spit. Stage 8 โ€” Swallow.
๐Ÿ’ก TipsFood play is central to SOS โ€” rolling food, making faces with food, sorting by colour are all valid therapeutic activities. NEVER force a child to eat โ€” pressure creates lasting aversions. Progress is measured in months, not sessions.
Oral-Motor Warm-Up Exercises
6.3
โ˜… Easyโฑ 5โ€“8 min before meals
๐ŸŽฏ Prepare the oral-motor system for eating; reduce hypersensitivity inside the mouth; improve jaw grading
  1. Jaw stretches: open wide (5 seconds), close slowly โ€” 10 reps
  2. Cheek puffs: inflate cheeks with air, hold 3 seconds, release slowly โ€” 10 reps
  3. Tongue push: press tongue firmly against roof of mouth for 5 seconds โ€” 10 reps
  4. Tongue circles: rotate tongue around lips clockwise then anti-clockwise โ€” 5 each direction
  5. Straw drinking: drink a thick smoothie through a narrow straw (resistive sucking) โ€” 2 minutes
  6. Vibrating toothbrush inside the mouth: gentle pressure on gums and cheeks for 1 minute before the meal
๐Ÿ’ก TipsThese exercises desensitise the mouth before food contact โ€” dramatically improves tolerance for new textures. Performed consistently before every meal, effects accumulate over 4โ€“6 weeks.
Scent Desensitisation Programme
6.4
โ˜…โ˜… Moderateโฑ 10 min ยท 3ร—/wk
๐ŸŽฏ Reduce avoidance response to specific triggering scents through graded exposure
  1. Create an olfactory hierarchy: 10 scents from neutral to most triggering
  2. Begin with scent 1 (neutral): sniff from 30 cm away โ€” 3 sniffs, then reward
  3. Week 2: sniff from 15 cm โ€” 3 sniffs
  4. Week 3: sniff from 5 cm โ€” 3 sniffs
  5. Week 4: move to scent 2 (mildly unpleasant) at 30 cm distance
  6. Always pair exposure with a preferred calming activity (weighted blanket, fidget)
๐Ÿ’ก TipsIf a scent is unavoidable (e.g., school cafeteria), the child's personal preferred scent inhaler can serve as olfactory 'camouflage'. Never introduce a strongly triggering scent without 3 sessions on milder scents first.
