Module 2: Oral Aversion

What is Oral Aversion?

  • Definition: Feeding aversion occurs when a competent baby (one with adequate oral function who was previously feeding well) refuses to feed.
  • Can start as early as seven weeks of age.
  • Aversion can be to breast, bottle, or solids, or to the entire process of eating.

Signs and Symptoms

  • Cries or screams when bib is placed around neck, put into feeding position, or shown the bottle.

  • Appears hungry but refuses to eat.

  • Eats only when ravenous.

  • On-off feeding pattern (unsustained feeding).

  • Eats only when distracted.

  • Feeds only while asleep or drowsy.

  • Consuming less milk or food than expected for age.

  • Displays poor growth.

  • Avoids eye contact with caregiver while feeding.

  • Rejects feeding while held in arms.

  • Accepts milk from another source.

  • Accepts water but not milk from the bottle.

  • Clamps mouth shut and turns head away from breast or bottle.

  • Fussing or crying when preparations are made for feeding time.

  • Taking a small amount of breast or bottled milk and then pulling away.

  • Not all babies present all signs and symptoms.

  • Babies with oral aversion show reluctance, avoidance, or fear of eating, drinking, or accepting sensation in or around the mouth.

Clarifications

  • A three-month-old that is distracted while feeding, and the mom needs to be in a very quiet place to feed this baby, that's not feeding aversion.
  • A baby that is fussy with the flow, but feet's okay if the flow is present, that's not feeling aversion.
  • Feeding aversion is a competent baby who was feeding fine, now it's not, even if hungry, refuses to eat.

Refusal vs. Aversion

  • Refusal:
    • Baby primarily breastfed, may have fed from bottle occasionally.
    • May have fussed a little with the bottle when younger.
    • May play with the bottle but not eat from it.
    • There might be an anatomical issue or not.
  • Aversion:
    • Usually seen in a baby that is fully bottle fed.
    • Low intake and very small volumes at each feed.
    • Cries or screams at sight of bottle.
    • Only feeds when asleep or distracted.
    • No anatomical issues or sucking problems.
    • Behavioral issues are acquired.

Common Signs of Oral/Feeding Aversion

  • Reacts for no obvious reason (distress appears unprovoked).
  • Baby is not coughing or choking while feeding or physically uncomfortable while feeding.
  • Feeding only when distracted (walking, rocking, bouncing, using screens, etc.).
  • Conflicted behavior: accepts the teat, sucks a few times, then cries, arches, fusses, latches on again, repeating the cycle.
  • Appears hungry but doesn't feed consistently; misinterpreted as sucking issues or pain.
  • Sometimes seen after procedures like tongue releases.

Pain vs. Feeding Aversion

  • Stress due to pain lingers long after feeding.
  • Stress due to aversion will stop after feeding.

Suck Issues vs. Aversion

  • Suck issues: history of sucking issues before seven weeks of age.
  • Aversion: past experiences, such as procedures (e.g., tongue-tie release) or pressure feeding.

Consequences of Misdiagnosis

  • Mistaking aversion for sucking problems or pain can lead to incorrect and potentially harmful interventions (e.g., unnecessary oral work).

Feeding Well When Drowsy or Asleep

  • Two-thirds of babies with feeding aversion present this symptom.
  • Parents discover baby feeds better while asleep, so they eventually don't even try to feed the baby while awake.
  • One-third of babies end up exclusively feeding while asleep.

Accepting Water, But Not Milk

  • Rule out high lipase by scalding the milk.
  • If not high lipase, consider past experiences related to stressful or frightening feeding episodes.
  • The trigger might not be the bottle but the milk itself, often related to pressure feeding.

Causes of Oral Aversion

  • Common in preemies due to unpleasant NICU experiences or limited oral stimulation.
  • Can start from birth, especially in babies fed with a feeding tube.
  • Consistent characteristic: defensive and fearful behavior regarding food, drinks, or objects related to feeding.
  • Motor issue: difficulty moving food/milk through the mouth due to muscle weakness, anatomical issues, or poor coordination.
  • Sensory issues: hypersensitivity to the feeling of food/milk in or near the mouth.
  • Fear: of negative consequences like choking, triggered by traumatic events (bitter taste, choking, oral trauma/surgery) or repeated events (frequent gagging, pressure feeding).

Risk of Oral Aversion

  • Frustration for parents, caregivers, and babies.
  • Psychosocial and medical complications, including compromised development and impaired parent-infant bonding.
  • Infant and parental distress.
  • Parental lack of confidence.
  • Poor growth.
  • Social isolation due to feeding rituals.

Prevention

  • Early sensory input in the NICU.
  • Thorough assessment before tongue-tie release.
  • Responsive feeding vs. paced feeding.
  • Encouraging feeding on demand and intuitive parenting.
  • Multidisciplinary approach to feeding management.

Management

  • Team of specialists working together.
  • Gentle feeding techniques.
  • Responsive feeding techniques.
  • Lactation care and a plan to maintain supply if applicable.
  • Pain control and pleasant touch on the face.
  • Feeding tube as an option if necessary.
  • Interdisciplinary team: pediatrician, gastroenterologist, SLP, nutritionist, occupational therapist, physiotherapist, psychologist, and social worker.
  • Strategies:
    • Stop pressure feeding.
    • Teach responsive feeding.
    • Create a positive atmosphere around feedings.
    • Use oral motor toys.
    • Practice with pretend foods and toys outside of mealtimes.
    • Consistency and patience (progress may not be linear).
    • Extended support.

Scope of Practice for IBCLCs

  • It is not within a lactation consultant's scope of practice to "treat" oral aversion, per se.
  • Understand causes, prevention, and identification of oral aversion vs. refusal.
  • Know how oral aversion is managed and when to refer out. Focus on bottle refusal and breast refusal.
