“That’s Not Fair!” Managing Siblings When One Child Is a Picky or Selective Eater

If you have more than one child and one needs special food accommodations while the other doesn’t, mealtimes can become VERY stressful.  And we all know it is already hard!  This is one of the most common struggles families face when a child has highly selective eating or ARFID. 

I often hear: 

• “It feels unfair.” 
• “It makes them fight” 
• “I feel guilty having different food rules.” 

Let’s start with an important reframe:

Fair does not mean identical. 

Meeting different needs within the same family is not favoritism - it’s responsive parenting. And yes, boundaries are still okay, even when one child needs extra support around food. Depending on the age and level of your kids, you can explain it in terms they may understand: 

“Ava uses swimmies when we are in the pool because they help her for now. You don’t need them anymore, but she still does. That way we all swim safely, but it may look a little different.” 

OR 

“Cooper uses glasses because it helps him see. You don’t need them to help you because your eyes see things more clearly. From now on, Cooper will have glasses, but you won’t.” 

Tips for Supporting All of Your Children 

Below are five practical, realistic tips to help you support all of your children while keeping mealtime calmer and more predictable. 

1. Name the Difference-Without Apologizing for It 

Children are incredibly perceptive. When differences aren’t acknowledged, kids often fill in the gaps themselves - and not always accurately. 

Use simple, neutral language such as: 

“Your sibling’s brain and body experience food differently, so they need some extra support right now.” 

You don’t need a long explanation or a justification. The more back and forth negotiations we go through, the more challenging it becomes. When differences are named calmly and confidently, they’re easier for children to accept. 

You are not creating inequality. You are responding to different needs. 

2. Keep the Structure the Same (Even If the Plates Look Different) 

One child may need: 

• A specific brand or texture 
• A preferred ‘safe food’ 
• Food presented separately 

That does not mean you need separate meals, separate times, or separate rules. 

Helpful boundary to keep: 

• Same mealtime 
• Same table 
• Same expectation of sitting together 

Different plates are okay. Different routines are not required. 

Consistent structure creates safety for both the selective eater and their sibling. 

3. Quietly Accommodate-Without Making One Child the “Exception” 

When parents feel anxious, they often narrate accommodations out loud: 

• “He HAS to eat this.” 
• “She can’t handle that.” 
• “This is all he’ll eat.” 

While well-intentioned, this can increase comparison and resentment between siblings. 

Instead, keep accommodations low-key and matter-of-fact. 

Less commentary means: 

• Less sibling comparison 
• Fewer power struggles 
• Less attention on food differences 

Food doesn’t need to become the family’s main storyline. 

4. Allow Feelings-Without Removing the Boundary 

Your non-selective eater might say: 

• “That’s not fair.” 
• “Why do they get different food?” 
• “Why do I have to eat this?” 

These reactions are normal. 

You don’t need to fix the feeling or change the rule. 

Try responding with: 

“I hear that this feels frustrating. And my job is still to make decisions that help everyone.” 

Validating feelings does not mean changing the boundary. This teaches an essential life skill: feelings are allowed, even when limits stay in place. 

5. Remember: Boundaries Lower Anxiety (Even Around Food) 

Many parents worry: 

• “Am I being too strict?” 
• “Am I making food more stressful?” 

In reality, clear boundaries reduce anxiety, especially in families navigating selective eating or ARFID. 

Boundaries communicate: 

• “You’re safe.” 
• “I’m in charge.” 
• “You don’t have to manage this alone.” 

Children-including selective eaters-feel calmer when adults confidently hold the structure. 

A Final Note for Parents 

You can: 

• Support one child’s food needs without over-accommodating the entire household 
• Hold boundaries without being rigid or unkind 
• Care for your selective eater and protect your other child’s emotional experience 
• Explain things in terms they understand so they will note the difference but not feel that it is unfair. 

If this feels hard, you are not alone. It is! But learning some simple strategies and changing your wording can make all the difference in the world.
