How to Help Autistic Children Try New Foods

If you have kids over 6 months, you’ve likely experienced the dinner table standoff. How does my 7-month-old already know she can seal her lips shut as I’m approaching her mouth with a spoonful of pureed carrots, rendering my attempts to feed her a nutritious dinner completely ineffective? It’s cute…the first time they do it. And it’s easier to ignore when you are confident that your child is getting nutrition from other sources. What’s the right response, however, when your child’s diet consists completely of chicken nuggets and fish-shaped crackers? Suddenly, refusing the food in front of them means they get no protein for the day.            

Parenting a child with extreme food restrictions is exhausting. Maybe your child used to eat a wider variety, but now exists solely on three or four specific, brand-loyal “safe foods.” The stress and worry you may feel over your child’s diet is valid and normal. While most children go through phases of picky eating that don’t require intervention, severe food selectivity can have several contributing factors, including sensory differences, oral-motor difficulties, medical concerns, and a strong preference for predictability. Today, we’ll examine low-pressure methods to help expand your child’s diet without turning dinnertime into a battleground.

Why Autistic Children Struggle with Foods

There aren’t black-and-white answers as to why children on the autism spectrum may have difficulty with eating routines. For some kids, the struggles are specifically related to trying novel foods. Other children struggle with all the sensory input that comes with eating. Let’s look at a few reasons that might contribute to the ongoing battle:

• Sensory Processing Differences: Intense sensitivity to textures (pureed vs. crunchy), temperatures, strong aromas, or visual presentation (such as foods touching on a plate).
• Brand and Visual Inconsistency: A child may eat one specific brand of chicken nuggets because it looks and tastes identical every time, but reject a homemade version because of natural variations in shape or color.
• Oral-Motor Fatigue: Chewing tough textures (like meats or raw vegetables) requires motor planning and jaw strength that can feel exhausting or overwhelming, especially to a child with developmental delays.
• Underlying Discomfort: Undiagnosed gastrointestinal discomfort, acid reflux, or constipation that makes eating certain foods physically unpleasant.

What do you expect when you pick up a blueberry to eat? The outside is smooth and slightly firm in your fingers. You pop it into your mouth and bite down to taste the equal-parts sweet and tangy flesh of the berry. Until, that is, you get a bad pint of berries from the store. One berry is perfect, the next is so sour your eyes water. A few more decent ones, then a blueberry that’s so mushy it falls apart in your hand. You give up and grab a bag of pretzel sticks. Each pull from the bag yields the same result: a crunchy stick with salt. You can predict almost always what will happen and what you will taste with each bite. To a child with autism, the predictability of a snack like pretzels may feel much safer and more manageable than the uncertainty of a food that can look, smell, or taste different from one bite to the next.

The Food Exposure Ladder: Exploring Without Eating

In my experience, the biggest obstacle to addressing a child’s struggles with eating or food refusal is that parents often expect to be able to start with the end goal: eating. We also want children to learn that they can explore food without fear. That they can tolerate something unfamiliar on their plate. That they can communicate “no,” “all done,” or “help” when something is uncomfortable. This is how your child will eventually experience new textures, smells, temperatures, and flavors without every meal becoming a battle. In reality, many smaller steps build up to fully chewing and swallowing a bite of food. Below, you’ll find the steps I’ve used when working on feeding with a child:

These steps don’t necessarily happen in a perfectly straight line. A child may move forward, move backward, or become comfortable with one step while needing more time with another. The goal is to identify a manageable level of interaction and build from there.

Feeding therapy is stressful on both parents and children. I want to clearly distinguish between goals targeting eating and goals targeting meal times. Many children on the autism spectrum may struggle with the skills required to sit and eat a meal. A child can have difficulty with:

• eating new foods
• sitting at the table
• using utensils
• communicating during meals
• tolerating food near them
• requesting help
• remaining at the table

Those aren’t all the same problem. If your child has both food aversions and struggles behaviorally at meal times, I urge you to keep in mind that the process will likely be lengthy and at times uncomfortable. These skills may seem small when you work on them one at a time, but they can meaningfully affect your child’s independence and ability to participate in everyday meals.

At-Home Strategies to Lower Mealtime Anxiety

You don’t have to make earth-shattering changes to your child’s diet to start making mealtimes easier. In fact, introducing too many new foods at once can make the process more stressful for everyone. Instead, start with small changes that make new foods feel predictable, manageable, and less threatening.

• Start With Foods Your Child Already Likes: One of the easiest ways to introduce a new food is to start with something your child already accepts. This is sometimes called food chaining, and the basic idea is to make small changes between a preferred food and a new food rather than jumping from one extreme to the other.
• Micro-Portions: Serve a portion the size of a single pea alongside preferred safe foods. A full serving might be visually overwhelming and imply that your child has to eat it all. My toddler would probably think it’s hilarious to find a single pea on her plate at dinnertime.
• Avoid the “Just One Bite” Rule: Repeatedly pressuring a child to eat can turn the food itself into something they associate with stress, negotiation, or conflict. Instead of making swallowing the measure of success, look for smaller opportunities to reinforce cooperation and exploration.
• Give Your Child Appropriate Choices: Children are often more willing to participate when they have some control over what happens. This doesn’t mean letting your child decide they will only eat chicken nuggets for every meal. Instead, offer small, manageable choices within the boundaries you’ve already established.

How ABA Therapy Can Help

ABA therapy can be part of a larger feeding plan for children with significant food selectivity. The goal isn’t to force a child to eat foods they find aversive. Instead, a behavior analyst can identify the specific behaviors and environmental factors surrounding eating, then build a gradual plan that meets your child where they are.

• Identifying Clear Baselines: Before introducing new foods, a behavior analyst can look closely at what your child already accepts. Does your child prefer crunchy foods? Foods that are room temperature? Foods of a particular color? Specific brands? Foods that are separated on the plate? These details can help the team identify appropriate starting points instead of randomly presenting foods that are likely to be rejected.
• Building Gradual Exposure: A feeding plan may begin with something as simple as having a new food on the table. From there, the child might work toward tolerating the food on their plate, touching it, smelling it, bringing it toward their mouth, and eventually taking a bite. The exact steps will depend on the child. The goal is to make each step small enough that the child can experience success rather than becoming overwhelmed.
• Reinforcing Exploration: For some children, interacting with a new food is a significant accomplishment. A behavior analyst may use praise, preferred activities, toys, or other reinforcers. Over time, the plan can be adjusted as the child becomes more comfortable and explores foods more independently.
• Fading Prompts and Reinforcement: Ideally, your child won’t need a therapist sitting beside them offering rewards for every interaction with food forever. As new skills become easier, prompts and external reinforcement can gradually be reduced. The long-term goal is for the child to become more independent and comfortable around food rather than dependent on a specific reward system.
• Working With Other Professionals: Feeding concerns don’t always have a behavioral cause. A child who avoids certain textures because chewing is difficult needs a different kind of support than a child who refuses a food because it is unfamiliar. A qualified team may include a pediatrician, registered dietitian, speech-language pathologist, occupational therapist, and/or feeding specialist, depending on the child’s needs. Consider medical concerns, nutritional needs, swallowing difficulties, and oral-motor skills alongside behavioral factors.

Remember that ABA is not a replacement for medical or feeding expertise. If your child coughs, chokes, gags frequently, has difficulty chewing or swallowing, loses weight, has significant gastrointestinal symptoms, or has a very limited diet that puts their nutrition at risk, talk with your child’s pediatrician and appropriate feeding professionals. Address those concerns before assuming your child simply needs more exposure to new foods. A responsible ABA provider should take potential medical, nutritional, swallowing, and oral-motor concerns seriously and coordinate with the child’s medical and feeding team when those concerns are present. Talk with your child’s pediatrician and/or feeding professional if you notice any of the following:

• your child’s diet is extremely limited or continues to become more restricted
• your child is losing weight or isn’t growing as expected
• eating causes frequent coughing, choking, or gagging
• Chewing or swallowing appears difficult
• constipation, reflux, vomiting, or other GI symptoms are affecting eating
• Meals consistently result in significant distress
• You’re concerned that your child isn’t meeting their nutritional needs

Conclusion

Helping an autistic child try new foods can be frustrating, slow, and exhausting. But feeding progress doesn’t have to mean taking a bite at every meal. Start where your child is comfortable, offer small opportunities to explore, and celebrate the little victories along the way. Remember that food refusal or avoidance can communicate something. When we understand what may be making a food difficult or overwhelming, we can better support our children without turning every meal into a battle.

Start small. Choose one preferred food to use as a bridge, offer one tiny portion of something new, and focus on tolerating and exploring rather than eating. If your child’s diet is extremely limited or you’re concerned about nutrition, chewing, swallowing, or other medical concerns, talk with your child’s pediatrician or feeding professionals. You don’t have to solve your child’s entire diet at once. Pick one small step and start there.
