OVERVIEW
What is a Feeding Disorder?
A feeding disorder refers to a condition where a child experiences difficulty eating, which may include issues with the act of eating, food refusal, or abnormal eating behaviors. These disorders can range from selective eating, where children have strong preferences for certain types of food, to more severe problems such as food refusal, which can lead to malnutrition or developmental delays.
​
According to the American Academy of Pediatrics (AAP), feeding disorders are often characterized by eating difficulties that interfere with a child’s ability to receive adequate nutrition and growth. They can be particularly challenging in young children, especially those with autism spectrum disorder (ASD) or other developmental conditions.
​
The World Health Organization (WHO) also defines feeding difficulties as a significant problem affecting a child’s overall health and development, often involving disruptions in the child’s ability to interact with food in a typical way, leading to nutritional imbalances and possible health consequences.
How common are feeding disorders?
Feeding disorders are a significant concern, especially among young children and those with developmental conditions such as autism. Here are some key statistics related to feeding disorders:
​
-
Prevalence in General Population:
-
According to the American Academy of Pediatrics (AAP), feeding problems occur in approximately 25-35% of typically developing children under the age of 5.
-
Studies suggest that up to 80% of children with developmental disabilities, including those with autism spectrum disorder (ASD), may experience feeding difficulties such as picky eating, food refusal, or aversions to certain textures and tastes.
-
-
Autism and Feeding difficulties:
-
Around 70-80% of children with autism spectrum disorder (ASD) are reported to have some form of feeding difficulty, with food aversion, picky eating, and food refusal being common.
-
A study published in the Journal of Autism and Developmental Disorders found that 60-80% of children with autism experience feeding difficulties, such as limited food preferences and difficulty with chewing or swallowing.
-
-
Food Refusal and Picky Eating:
-
Food refusal can affect up to 40% of children in the general population, though it is significantly more common in children with developmental conditions.
-
Picky eating is reported in approximately 50% of children under the age of 5, and this can persist into childhood, particularly in children with neurodevelopmental disorders like autism.
-
-
Impact on Growth and Nutrition:
-
Nutritional deficiencies are common among children with feeding disorders. Research indicates that children with feeding difficulties often face risks for poor weight gain or growth delays due to limited food intake or inability to consume a balanced diet.
-
Studies suggest that children with severe feeding disorders, such as food refusal, may have an increased risk for malnutrition and failure to thrive, which can impact their overall health and development.
-
-
Feeding Therapy and Success Rates:
-
Early intervention with feeding therapy can be highly effective. According to the American Speech-Language-Hearing Association (ASHA), children who receive early feeding therapy show improvementsin eating habits, with over 75% of children benefiting from tailored feeding interventions.
-
These statistics underscore the importance of early identification and intervention for feeding disorders, especially in children with autism, to improve their nutritional status and overall well-being.
01
Diagnosis
Feeding disorders in children with autism spectrum disorder (ASD) are typically identified when a child displays consistent food refusal, limited food preferences, or difficulty chewing and swallowing. Signs may include:
​
-
Picky eating: Refusal to try new foods, often sticking to a narrow range of foods.
-
Food aversion: Disliking certain food textures, colors, or smells.
-
Food refusal: Consistently refusing to eat meals or snacks.
-
Chewing issues: Difficulty chewing food properly or avoiding chewing altogether.
-
Feeding difficulties: Behavioral patterns that disrupt proper eating, such as gagging or choking.
Diagnosing feeding disorders involves a comprehensive assessment by a team of professionals, including pediatricians, speech therapists, and nutritionists, to identify any underlying sensory sensitivities or gastrointestinal issues contributing to eating problems in autism.
​
When a child exhibits feeding difficulties, it is essential to seek professional guidance to ensure proper diagnosis and treatment. Feeding disorders, especially in children with autism or other developmental conditions, may involve issues like picky eating, food refusal, swallowing difficulties, or sensory aversions.
Here’s a brief overview of key evaluations and specialists involved in diagnosing and treating feeding disorders.
​
1. Consulting the Primary Care Physician:
The first step when a child has feeding or swallowing problem is to consult their primary care physician. The physician will assess the child's overall health and may refer the child to specialists, depending on the severity of the problem. Early identification and referral ensure that the child receives the appropriate support.
​
2. Specialized Evaluations by Experts:
Depending on the severity of the issue, the physician may recommend a range of specialists:
-
Speech-Language Pathologist (SLP): An SLP will conduct a clinical evaluation of feeding and oral-motor skills to assess whether the child has difficulties with chewing, swallowing, or tolerating certain food textures.
-
Occupational Therapist (OT): OTs may be involved in addressing sensory sensitivities that affect eating habits.
-
Registered Dietitian: A dietitian can assess nutritional intake and offer strategies to improve the child’s diet, ensuring they receive the proper nutrition.
-
Lactation Consultant: For younger children, especially infants, lactation consultants may assist in feeding-related issues, particularly breastfeeding difficulties.
3. Video Fluoroscopic Swallowing Study (VSS):
When a child has difficulty swallowing, a Modified Barium Swallow (VSS) may be recommended. This diagnostic procedure involves the child consuming food and liquids while a radiologist and speech-language pathologist capture video X-rays of the child’s throat. This allows healthcare providers to observe how food and liquid move through the child’s mouth and throat, identifying any issues such as aspiration (food or liquid entering the airway), which could lead to choking or respiratory issues.
4. Fiberoptic Endoscopic Evaluation of Swallowing (FEES):
Another useful diagnostic procedure is the Fiberoptic Endoscopic Evaluation of Swallowing (FEES). This test involves inserting a thin scope through the child’s nose to observe the swallowing process. A speech-language pathologist and ENT specialist use this procedure to view the child’s ability to protect the airway during swallowing, helping to detect any issues such as aspiration or swallowing difficulties.
5. Treatment and Intervention:
Once a diagnosis is made, intervention can include feeding therapy, behavioral strategies, and sensory integrationtherapies to address any oral-motor or behavioral feeding issues. In some cases, feeding therapy for autism may be necessary to help the child overcome food aversions or develop new eating habits.
02
Risk Factors
Feeding disorders in children can be caused by a variety of factors, including medical conditions, developmental challenges, and environmental influences. Understanding these risk factors and causes is crucial for early identification and intervention.
​
1. Developmental and Neurological Conditions:
​
-
Autism Spectrum Disorder (ASD): Children with autism often experience feeding disorders due to sensory sensitivities, food aversions, and difficulty with oral-motor skills. Autism and feeding difficulties are common, with 70-80% of children with ASD experiencing feeding problems, such as food refusal, selective eating, and food aversion.
-
Sensory Processing Disorders: Children with sensory processing issues may struggle with certain textures, tastes, or smells of food, leading to selective eating or food aversions. They may refuse to eat certain foods based on texture, color, or consistency.
-
Developmental Delays: Children with general developmental delays may take longer to develop oral-motor skills (such as chewing and swallowing), which can interfere with their ability to eat properly.
2. Medical Conditions:
​
-
Gastrointestinal Issues: Conditions like gastroesophageal reflux disease (GERD), constipation, or allergies can make eating uncomfortable, leading to food refusal or picky eating. Children with feeding disorders may have difficulty tolerating food due to physical discomfort caused by gastrointestinal issues.
-
Swallowing and Oral-Motor Dysfunction: Conditions that affect the muscles or coordination required for eating and swallowing, such as dysphagia, can result in feeding problems. Children may have difficulty chewing or swallowing, which can cause choking or discomfort.
-
Food Allergies and Sensitivities: Some children develop autism feeding issues due to food allergies or intolerances, which may cause negative reactions to certain foods. This can result in avoidance behaviors or limited food acceptance.
3. Behavioral and Psychological Factors:
​
-
Food Refusal and Selective Eating: Picky eating or food refusal can develop as a learned behavior, where children become accustomed to refusing certain foods. This may be due to previous negative experiences with eating or as a way of exercising control over their environment.
-
Parental Feeding Practices: Overly controlling feeding practices or using food as a reward or punishment can influence a child’s eating habits, leading to feeding disorders. Conversely, lack of structure or inconsistent mealtime routines can also contribute to poor eating behaviors.
-
Anxiety and Stress: Emotional distress, trauma, or anxiety may contribute to feeding difficulties. Children may avoid eating due to emotional associations with food or mealtimes.
4. Environmental and Social Factors:
​
-
Family History: A family history of feeding problems, eating disorders, or gastrointestinal issues may increase the likelihood of a child developing feeding difficulties.
-
Socioeconomic Factors: Children from lower socioeconomic backgrounds may have limited access to nutritious food, which can contribute to poor eating habits or developmental feeding issues.
-
Cultural Influences: Cultural beliefs about food and mealtimes can influence a child’s relationship with food. In some cultures, specific foods may be preferred or avoided, which can impact a child's food acceptance.
5. Prematurity and Birth Complications:
​
-
Premature Birth: Premature infants may have underdeveloped oral-motor skills and may experience challenges with sucking, swallowing, and feeding. Early feeding difficulties can persist into childhood.
-
Medical Complications at Birth: Children who experience medical complications at birth, such as low birth weight or respiratory issues, may develop feeding disorders due to delayed developmental milestones, oral-motor dysfunction, or physical discomfort while feeding.
03
Treatment
The treatment of feeding disorders in children is multifaceted, involving interventions to address both the physical and psychological aspects of eating. The aim is to improve the child’s ability to eat safely, develop healthy eating habits, and ensure proper growth and nutrition. Below are the common treatment strategies, supported by evidence and studies on their effectiveness:
​
1. Feeding Therapy
Feeding therapy is often the cornerstone of treatment for children with feeding disorders. Conducted by speech-language pathologists (SLPs), occupational therapists (OTs), and other specialists, feeding therapy helps children improve their oral-motor skills, such as chewing, swallowing, and managing food textures. Therapy may include:
-
Desensitization to different textures and tastes.
-
Oral-motor exercises to improve chewing and swallowing skills.
-
Safe feeding techniques to help children overcome aversions to certain foods or textures.
Effectiveness:
Studies show that feeding therapy can significantly improve the feeding behaviors of children with feeding disorders. According to a review in the Journal of Pediatric Gastroenterology and Nutrition, approximately 70-80% of childrenwho receive early feeding therapy show improvements in their eating habits. In children with autism spectrum disorder (ASD), therapy can also help reduce food aversions and expand food preferences, especially when combined with sensory integration techniques.
2. Behavioral Strategies
Behavioral therapy focuses on changing the child’s relationship with food by encouraging positive behaviors during mealtimes. Common strategies include:
-
Positive reinforcement for eating new or challenging foods.
-
Gradual exposure to feared foods (systematic desensitization).
-
Token systems or reward charts to motivate children to try new foods or finish meals.
-
Mealtime structure to create a predictable routine and reduce anxiety.
Effectiveness:
Research has shown that behavioral interventions can be very effective, especially in reducing food refusal and encouraging children to try new foods. A study published in the Journal of Applied Behavior Analysis found that 85-90% of children who underwent behavioral interventions showed improvements in food acceptance and mealtime behavior.
3. Dietary Support
Consulting with a pediatric nutritionist or dietitian is essential for ensuring that children with feeding disorders receive adequate nutrition. A registered dietitian can:
-
Develop individualized meal plans to meet the child’s nutritional needs.
-
Identify food sensitivities or allergies that may be contributing to food refusal.
-
Work with families to create mealtime routines that support healthy eating.
Effectiveness:
Dietary interventions are crucial in preventing nutritional deficiencies that can arise due to selective eating or food refusal. In children with feeding difficulties, research indicates that nutritional support can improve growth rates, address deficiencies, and promote healthy eating habits. For instance, a study in the American Journal of Clinical Nutrition found that children receiving individualized dietary counseling showed improvements in weight gain and overall health.
4. Medical Interventions
In some cases, medical interventions may be necessary to address underlying physical causes of feeding difficulties. These may include:
-
Gastrostomy tubes (G-tubes) or nasogastric tubes for children who are unable to meet their nutritional needs by mouth.
-
Medication for managing conditions like gastroesophageal reflux disease (GERD), which can affect eating and swallowing.
-
Oral-motor therapy to address specific muscle or coordination problems related to swallowing.
5. Multidisciplinary Approach
A team-based approach involving pediatricians, speech-language pathologists, occupational therapists, nutritionists, and behavioral therapists is often the most effective way to treat feeding disorders. This approach allows professionals to address all aspects of the child's feeding difficulties, including sensory sensitivities, oral-motor deficits, behavioral issues, and nutritional needs.
Studies and Evidence on Improvement Rates
-
A 2017 study published in the Journal of Developmental and Behavioral Pediatrics found that 75-80% of children who participated in a structured feeding therapy program showed significant improvements in food acceptance and mealtime behavior, especially when therapy was started early.
-
According to a study in the Journal of Autism and Developmental Disorders, feeding therapies, combined with behavioral interventions, improved eating habits in over 70% of children with ASD. The study found that children who received comprehensive therapy were more likely to develop healthy, diverse eating habits and show less food refusal over time.
-
A systematic review published in Clinical Nutrition noted that early intervention with a multidisciplinary approach, including feeding therapy, behavior therapy, and dietary support, resulted in improved growth and nutritional status for 70-85% of children with feeding disorders.

Tips for Parents
Managing a child with a feeding disorder can be challenging, but with the right strategies, parents can help their child develop healthy eating habits and overcome feeding difficulties. Here are some practical tips for parents:
1. Create a Calm and Positive Mealtime Environment
-
Minimize distractions: Turn off the TV, put away toys, and focus on the child during mealtimes to help them concentrate on eating.
-
Keep it relaxed: Avoid pressure to eat or long drawn-out mealtimes. A relaxed, positive atmosphere can help reduce anxiety and create positive associations with food.
-
Routine is key: Try to maintain consistent meal times and snack schedules to help the child feel secure and know what to expect.
2. Introduce New Foods Gradually
-
Small steps: Start by offering a small portion of a new food alongside familiar foods that the child already likes. Gradually increase the variety over time.
-
Sensory exposure: Encourage the child to explore new foods by touching, smelling, or playing with them before trying to eat them. This can help reduce food aversions.
-
Modeling: Eat the same foods in front of your child to demonstrate how to enjoy them, making mealtimes more engaging and less stressful.
3. Use Positive Reinforcement
-
Praise and rewards: Celebrate every small success, whether it's trying a new food or taking a few bites. Praise the child for their effort, not just for finishing the meal.
-
Reward charts: Use a reward system (like stickers or tokens) to encourage trying new foods or following mealtime rules. Make sure the rewards are meaningful to the child.
4. Be Patient and Consistent
-
Avoid pressure: Pushing a child to eat a certain food can lead to increased resistance. Allow them to take their time and explore foods at their own pace.
-
Consistency is key: Keep offering a variety of foods regularly, even if they are refused at first. Repeated exposure over time can lead to acceptance.
-
Stay calm during refusal: Children may refuse to eat, but it’s important to stay calm and not react negatively. Pressuring or scolding them can increase food anxiety.
5. Make Food Fun
-
Creative presentation: Cut fruits, vegetables, and other foods into fun shapes, or create food art on the plate to make mealtimes more engaging.
-
Involve the child: Let your child help with meal preparation or pick out the fruits and vegetables at the store. This can increase their interest in the food and make them feel more involved.
-
Offer choices: Giving your child the opportunity to choose between two healthy options empowers them and makes them feel more in control.
6. Address Sensory Sensitivities
-
Be mindful of textures and temperatures: Some children with feeding disorders, especially those with autism, may have sensory sensitivities to certain textures or temperatures. Experiment with different food textures (smooth, crunchy, or soft) and offer foods at various temperatures to find what your child prefers.
-
Gradual desensitization: If your child is sensitive to certain textures or smells, gradually expose them to those foods in a non-threatening way. Start by allowing them to smell or touch the food before trying it.
7. Consider Professional Support
-
Speech-language pathologist (SLP): If your child struggles with chewing or swallowing, consider working with an SLP to improve oral-motor skills and address any swallowing issues.
-
Occupational therapy (OT): OTs can help with sensory processing difficulties and develop strategies to manage food aversions and improve fine motor skills needed for feeding.
-
Consult a dietitian: A pediatric dietitian can offer personalized meal plans and help ensure your child is getting the necessary nutrients for growth and development.
8. Be Flexible and Adaptable
-
Offer familiar foods alongside new ones: If a child is particularly resistant to trying new foods, always serve them a familiar food alongside the new option to make the experience less overwhelming.
-
Adjust portion sizes: Smaller portions may seem less intimidating, especially when introducing new foods. If necessary, offer multiple smaller meals or snacks throughout the day.
9. Monitor for Underlying Medical Conditions
-
Check for gastrointestinal issues: If your child has signs of reflux, constipation, or other digestive issues, consult a healthcare provider. Medical conditions like these can often contribute to feeding problems.
-
Food allergies or intolerances: If a child has food allergies or intolerances, work with a pediatrician or allergist to identify and eliminate problematic foods from their diet.
10. Educate Yourself
-
Understand the disorder: Educate yourself about feeding disorders and specific conditions like autism that may contribute to eating difficulties. This knowledge will help you approach mealtime challenges with more empathy and patience.
-
Stay informed on strategies: Look for resources, books, and support groups for parents managing feeding disorders. Connecting with others who face similar challenges can provide valuable support and ideas.
