Babies who exhibit oral aversion (the reluctance, avoidance, or fear of eating, drinking, or accepting sensation in or around the mouth) refuse to eat or experience significant distress during feeding, causing them to receive inadequate nutrition.
Signs and Symptoms
Signs of oral aversion include:
Appearing hungry but refusing to eatClamping his or her mouth shut and turning his or her head away from the breast or bottleConsuming less milk or food than expected for ageDisplaying poor growthFeeding only while drowsy or asleepFussing or crying when preparations are made for feeding time, such as when placed in a feeding position or when presenting a bottleTaking a small amount of breast or bottle milk and then pulling away
Causes
A sensory-based feeding disorder, oral aversion is more common in premature babies, and especially those who have experienced a longer stay in the neonatal intensive care unit (NICU) because of unpleasant stimuli to their mouths or faces they have experienced during treatments. NICU procedures that may increase the risk for oral aversions include:
Frequent suctioning Inappropriate oral feedings in the NICU Intubation and mechanical ventilation Long-term use of NG or OG tubes
Risks
Oral aversion can be very frustrating for parents, caregivers, and the babies themselves. There are many psychosocial and medical complications of feeding difficulties, including:
Compromised developmentImpaired parent/infant bondingInfant and parental distressParental lack of confidencePoor growthSocial isolation
Treatment
Treating infants with oral aversion may involve collaboration from a multidisciplinary group of specialists, including neonatologists, speech pathologists, occupational therapists, and other professionals who specialize in the care of infants. If behavioral therapies fail to help an infant overcome oral aversion, a feeding tube may be considered. Feeding tubes, although frightening at first, can help ease some of the anxiety for both parents and babies, and allow adequate nutritional intake for growth and development. Feeding tubes are generally very safe and effective, carrying only minimal risks such as irritation of the nose, mouth or stomach.
