Is your child a picky eater?
Have you been told that they’ll just eat when they’re hungry? Or that picky eating is a behavioral issue or phase they will outgrow?
I get it! There is so much well-intended yet misleading advice when it comes to picky eating.
For many kids – especially those with multiple food allergies – picky eating can actually be the first sign of a feeding problem.
This comprehensive article will explain what picky eating is, when to be concerned, how to navigate selective eating, and tips for feeding picky eaters.

What is picky eating?
Surprisingly, picky eating is not easy to define.
There is no universal definition within the field of pediatric feeding therapy. Picky eating is not an ICD-10 medical diagnosis.
Instead, picky eating is a term generally used to describe those that:
eat a limited variety of foods,
are reluctant to try new foods, or
have strong preferences for taste, texture, and/or food preparation.
Picky eating is also known as selective eating or fussy eating. For a softer approach, terms like finicky or particular are often used as destigmatized alternatives.
How common is it?
In the United States, caregivers report 19% of four-month-olds and up to 50% of two-year-olds are picky eaters. (1)
Another study suggests that 20% of children between two and six years old have moderate or severe selective eating. (2)
Remember, there is no standard definition for picky eating. This makes it more difficult to pinpoint precise prevalence statistics.
For example, if a study uses a more general description of picky eating, the data could imply it is more prevalent. On the other hand, it would appear less common if more stringent criteria are used to define picky eating.
Regardless, we know that many kids (especially toddlers) are picky eaters. The next question is, why?
What causes picky eating?
In my clinical experience, picky eating is usually not caused by the parents.
There is research that supports this. A 2008 study found that feeding problems were not associated with parenting practices or poor feeding techniques. Instead, picky eating is caused by a combination of biological factors, sensory processing and texture aversions, psychological factors, and medical conditions. (3)
For some kids, picky eating is just a phase. About one third of children who are picky at either 18 months or 3 years will outgrow it by 6 years of age. (4)
But only 8% of picky eaters will outgrow it at age six if they are reported picky at both 18 months and three years. (4) And 14% of children with the highest food fussiness scores in a Michigan Head Start study actually became more selective over time. (5)
So if you are a parent of a picky eater, should you be concerned? If picky eating occurs on a spectrum, how do you know if your child will outgrow it, remain picky, or become more selective?
Could picky eating be a red flag for an underlying feeding concern?
What is the difference between picky eating and Pediatric Feeding Disorder?
Sometimes what appears to be picky eating is actually the tip of the iceberg for underlying feeding problems or developmental concerns.
In 2021, Pediatric Feeding Disorder (PFD) became a medical diagnosis with its own ICD-10 code, in large part due to the advocacy work of a group called Feeding Matters.
PFD is defined as an “impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction. (6)
Feeding is a complex process that involves interactions between an individual’s organ systems, sensory processing, development, environment, learning capacity, and nutritional status. Because these factors are interconnected, a struggle in any one area can easily cause challenges in the others.
A list of feeding concerns that could occur in the four domains is listed in the box below. Medical conditions most likely to impact feeding in children under five years include respiratory, gastrointestinal, prematurity, congenital, neurological, and cardiac disorders. (7)
Compared to picky eating, PFD is usually more complex. Children with PFD have a smaller amount of food preferences and may avoid food groups or categories of food. They are also more likely to have a meltdown when new foods are introduced and take longer to eat new foods.
Additionally, PFD often requires a multidisciplinary treatment team. This often includes a registered dietitian for nutrition and occupational or speech language pathologist that specialize in feeding therapy.
Why is picky eating a concern in kids with food allergies?
Kids with food allergies are more likely to have feeding concerns than those without allergies. (8) And as the number of food allergies increases, the prevalence of feeding difficulties also increases. (9)
In the general population, picking eating after 14 months of age is associated with a lower enjoyment of food, being less likely to eat when upset at meals or snacks, and a higher desire to drink milk than eat table food. (10) The addition of food allergies can place selective eaters at higher risk for nutrition concerns and growth faltering.
Fear of trying new foods
When a family is learning how to manage a new food allergy, it can be scary to introduce new foods.
In my clinical experience, when parents are struggling with food allergy anxiety, it can make the mealtime experience less enjoyable for everyone. In fact, a parent’s anxiety during mealtimes is directly connected to their perception of their child’s food allergy. Specifically, these worries stem from a constant risk of allergen exposure and the toll it takes on their child’s quality of life. (11)
Introducing new foods suddenly becomes a trigger for severe anxiety over possible allergic reactions. Parents then unintentionally instill a conditioned fear response in their child that any unfamiliar food is unsafe.
This is concerning because children’s food preferences are mostly established by 2-3 years of age. And unsurprisingly, kids that are afraid to try new foods tend to eat fewer foods. (12)
When kids have a smaller food range, it is becomes even more difficult to provide exposure to a wide variety of textures and flavors
Texture and sensory limitations
Trying new foods is an important developmental step for developing a taste for a large variety of foods.
When searching for safe alternatives to allergens, consider ways to replicate the texture and sensory properties the unsafe food in addition to nutrition. For example, peanut butter has a distinct creaminess and flavor. Introducing almond butter or sun butter to a child with a peanut allergy can provide a similar texture, color, and flavor.
To avoid discomfort or associated pain with eating, kids may develop a preference for highly predictable, safe textures and begin to reject anything unfamiliar or complex. Unfortunately, safe alternatives may have slightly different taste or consistency which could make a child less likely to try them, especially if they have a limited number of foods with different sensory properties.
In order to maximize the developmental window when infants and young toddlers are willing to try new textures, it is important to be on top of introducing new table foods for kids with food allergies. This can be especially tricky with young children with FPIES, as introduction of new foods is often altered or delayed.
Nutrient insufficiency
Kids with multiple food allergies have a higher risk for vitamin and/or mineral deficiencies.
Children that eat a larger variety of foods are more likely to meet their vitamin and mineral needs than those with a limited diet. (13) The cornerstone of food allergy management is allergen avoidance. But when entire food groups or types of food are eliminated, there is an increased risk for nutrient insufficiency.
Many of the Top 9 Food Allergens are found in core food groups. Avoiding common allergens like milk, egg, wheat, and soy can impact intake of important nutrients like energy, protein, calcium, and iron.
Finding appropriate substitutions is important for children to receive adequate nutrition and reduce risk of growth concerns.
Growth concerns
For many young kids, the onset of food allergy occurs at the same time as rapid growth.
An international study of children with food allergies found 9% had stunted height, 6% were underweight, and 5% were malnourished. Additionally, those with EoE or non-IgE-mediated food allergy (such as FPIES) were more likely to have lower height on growth charts. (14)
Adolescence is another life stage when nutrition is crucial to optimize growth. There is an increased need for nutrients like calcium, magnesium, protein, and energy, as well as iron for girls. The combination of multiple food allergies and selective eating can make getting adequate nutrition even more difficult during this time.
It is important to note that kids with food allergies are at increased risk for poor growth, but not all kids with food allergies will have poor growth.
Pressure to eat
The more that parents pressure a child to eat, the more likely a child will refuse to try new foods. This becomes a viscious cycle, because parents are more likely to pressure a child to eat that is a picky eater. (15)
Parents are also more likely to pressure their child to eat if they are concerned they are underweight. (16)
The combination of dietary elimination, feeding difficulties, inadequate nutrition, and growth concerns can all contribute to pressuring a child to eat, but also have mental health implications.
What is the difference between picky eating and ARFID?
Avoidant/Restrictive Food Intake Disorder (ARFID) is a broad term that describes several eating or feeding-related problems.
Unlike picky eating, ARFID is a clinically diagnosed eating disorder. It was included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) in 2013. Those with ARFID often have severely restricted food intake due to:
Low appetite, lack of interest in food, or difficulty with the act of eating
Sensory problems or food aversions
A deep fear of aversive consequences of eating, such as choking, pain, or nausea. (17)
ARFID is a chronic condition that interferes with daily functioning and quality of life, such as avoiding social situations due to paralyzing anxiety and fear of new foods.
Children with ARFID have an increased risk for nutrition deficiencies, growth concerns, dependence on tube feeding or nutrition supplement drinks, and the need for hospitalization related to malnutrition. (17)
Additionally, ARFID can negatively impact social and emotional development. As with other eating disorders, treatment requires a multidisciplinary team including primary care providers, psychiatrists, psychologists, nurses, dietitians, and occupational therapists.
What to do if you have concerns about your child’s eating
Here are some steps to help you take action if you have concerns about picky eating in your child with food allergies:
Step 1: Take the six-question screener (or the full questionnaire) available on the Feeding Matters website. If two or more answers are flagged, then please discuss your results with your child’s pediatrician or primary care provider. Additional information and resources are available from Feeding Matters
Step 2: Make a list of all the different foods that your child is currently eating in each food category (protein, starchy foods, and fruit/vegetables).
These should be foods that your child eats most of the time; do not include foods they sometimes eat or are no longer eating.
Be specific! Instead of chicken, write down all forms of chicken that your child eats (chicken nuggets, shredded chicken, deli chicken, etc.).
Step 3: Count the total number of foods that your child is currently eating. Is the number less than 30? Or are there any categories with only a few foods? Or no foods at all? If so, your child might benefit from further evaluation by a pediatric dietitian or feeding specialist.
Step 4: Think about what happens when your child is offered a new food. Can they tolerate it on their plate or close by on the table? Or do they regularly melt down when something new is presented? If so, your child might benefit from further evaluation by a feeding specialist or pediatric dietitian.
Step 5: Now consider your child’s food allergies. Do they have a milk allergy or multiple food allergies? Are you struggling to find a variety of safe and appropriate substitutions? Or have you gotten behind in introducing new foods? All of these situations would suggest your child might benefit from further evaluation by a pediatric food allergy dietitian.
How to find a food allergy dietitian near you
A pediatric dietitian understands the developmental milestones involved with growing and learning how to eat. Dietitians with additional training in feeding therapy will focus on the how and why of eating; not just what to eat.
Furthermore, a pediatric food allergy dietitian can help:
Identify safe alternatives
Recognize possible nutrient deficiencies
Create a patient-centered plan to introduce new foods.
Working with a food allergy dietitian can improve both growth parameters and nutrition status. (18)
Food Allergy Research & Education (FARE) allows you to search for a FARE Trained Registered Dietitian in your state. FARE’s Pediatric Food Allergy Course is a comprehensive nine-month program that provides training on both IgE-mediated and non-IgE-mediated food allergies.

Tips for feeding picky eaters
There are many different philosophies when it comes to working with picky eaters. I tend to favor the approaches that value autonomy and help nourish a healthy relationship with food an eating.
For example, the Division of Responsibility in Feeding is an approach that defines specific roles for both parents and children. It honors a child’s natural ability to eat as much as they need in order to grow in the way that is right for them.
Parents are responsible for what foods will be served, when meals are offered, and where the food is provided.
Children are responsible for how much to eat and whether or not ot eat each food that is offered.
Here are some additional tips to help you feed your picky eater:
Establish a feeding schedule with designated meal and snack times.
Introduce a variety of food from all the food groups.
Keep offering new foods - sometimes it can take up to 10-20 exposures (or more) before a child feels comfortable trying something new.
Make food fun by including your child in the meal planning and food preparation.
Talk about the sensory properties of food during the meal instead of focusing on what your child is (or isn’t) eating.
Serve new foods with familiar ones (try a deconstructed meal).
Offer regular family meals so adults can role model desired eating habits.
When introducing new foods, remember to check every label, every time as products can (and do) change:
Read ingredient lists for allergens or check for a Contains statement.
May contain statements and other Precautionary Allergen Labels are voluntary and unregulated.
Certified allergy-free products and “Nut-Free Facility” labels are helpful, but always double check the ingredient list!
Final thoughts
Picky eating is a general term used to describe children that are selective with their food choices, reluctant to try new foods, and have strong taste or texture preferences.
It is different from Pediatric Feeding Disorder and ARFID, which are both medical conditions that require diagnosis by a doctor.
While some kids will outgrow their picky eating, others will become even more selective. If you have concerns about your child’s eating, a pediatric food allergy dietitian can help pinpoint potential nutrition concerns and help increase variety in their diet.
