When a Brother or Sister Has sJIA: Supporting the Siblings Who Get Lost in the Storm

In the intensity of managing sJIA, siblings can quietly get lost. They love their brother or sister fiercely, they worry about things they don’t have words for, and they sometimes feel overlooked even in families who are trying their best. This guide is for them, and for the parents who love all of their kids equally and are doing their best in an impossible situation.

What Siblings Are Often Feeling (But Not Saying) #

Children are remarkably perceptive. Even young siblings pick up on fear, tension, and the weight of a serious diagnosis. What they often experience, and may not have the language for, runs deeper than most parents realize.

There is the fear. “Is my brother going to die? Will I get this too?” There is the guilt, the quiet shame of feeling happy on a day when their sibling is hurting. There is resentment, the frustration of cancelled plans and disrupted routines, and then the guilt that follows the resentment, because they know it isn’t their sibling’s fault.

There is loneliness, because their parents’ attention and energy are being pulled in a demanding direction. There is the pressure to be “the easy one,” to not add more stress to an already stressed family. And beneath all of it, there is a fierce protectiveness and a pride in their sibling that they may not know how to express.

None of these feelings make a sibling a bad person. They make them a child trying to make sense of something hard.

How to Talk to Your Other Children #

The conversations you have with siblings about sJIA will look different depending on their age. What matters most is that you have them at all.

For young children, ages three through six, keep it simple and reassuring. “Your brother has something in his body that sometimes makes him feel really sick. The doctors are helping him. It’s not your fault and you can’t catch it. We love you both the same.” At this age, children need to hear that they are safe, that it isn’t their fault, and that being loved hasn’t changed.

For children ages seven through eleven, you can offer more detail. “Corbin has a disease called sJIA. His immune system, the part of his body that fights germs, sometimes gets confused and attacks his own body instead. It causes a lot of pain and makes him very tired. The medicine helps, but some days are harder than others. We want you to be able to ask us anything about it.” Children in this age range need facts. They are already imagining the worst, and honest information is less frightening than the stories they are telling themselves.

For teenagers, include them. They can handle more honesty than we sometimes give them credit for. Include them in conversations about what sJIA means for the family. Ask for their input. Acknowledge the impact on them directly. “I know this has been hard on you too, and I want to hear about that.” Teenagers who feel respected and included are far more likely to stay connected than teenagers who feel shut out.

Questions to Check In With #

You don’t need a formal sit-down conversation every time. But checking in regularly, with real questions that invite real answers, makes a difference. Try asking, “Is there anything about Corbin’s illness that worries you or confuses you?” or “Have there been times you felt left out or like things weren’t fair? I want to hear that.” Ask them, “Is there something special you’d like to do, just you and me?” and “Do your friends know about Corbin? How do you feel about that?”

The questions themselves matter less than the message underneath them: your feelings are welcome here, and I am paying attention.

Protecting the Sibling Relationship #

Preserve One-on-One Time #

Even 30 minutes of undivided attention, reading together, a walk, their choice of activity, communicates that they matter and are seen. It does not need to be elaborate. It needs to be consistent. When a sibling knows that their time with you is protected, it changes the way they experience everything else.

Protect Their Activities #

When possible, siblings’ sports schedules, recitals, and school events should be treated as non-negotiable. When sJIA means a parent can’t attend, make a plan. Another trusted adult goes. The event is recorded. There is something special afterward. The goal is for the sibling to feel that their life matters too, that the family’s world does not revolve exclusively around the diagnosis.

Let Them Be Angry #

Siblings need permission to feel what they feel, including frustration, resentment, and sadness. When a sibling says “it’s not fair,” the most powerful response is often the simplest one. “I know it’s not fair.” Not a defense of the situation. Not an explanation. Just validation. Responding this way keeps communication open and teaches them that difficult feelings are safe to express in your family.

Acknowledge Them Explicitly #

Name what you see. “You have been really patient and flexible this month and it has not gone unnoticed. I’m proud of you.” Siblings who feel seen are more resilient than siblings who feel invisible. When you name their strength, they begin to believe in it themselves.

When Siblings Need Their Own Support #

Some siblings develop anxiety, behavioral changes, or signs of depression in response to a family member’s serious illness. Watch for significant changes in school performance or behavior. Watch for withdrawal from friends or activities they used to enjoy. Sleep disturbances, physical complaints like stomachaches or headaches without clear cause, and excessive worry about the sick sibling’s health or their own are all signals. Sometimes it shows up as acting out at home while holding it together elsewhere, or the reverse.

If you see these signs, consider a conversation with their school counselor. A few sessions with a child therapist, even as a check-in rather than long-term therapy, can make a real difference. A sibling support group can help them meet other kids who understand what they are going through.

Resources for Siblings #

Sibshops (Sibling Support Project) #

www.siblingsupport.org

Sibshops are peer support workshops specifically for siblings of children with special health and developmental needs. They combine recreation and discussion in a setting where kids can meet others who truly understand what it is like. Available in many communities and increasingly online, Sibshops give siblings a space where they are the focus for a change.

The organization behind Sibshops also maintains a wealth of articles, books, and resources specifically for families navigating the sibling dynamic in chronic illness. Their reading list for children and parents is excellent.

Books for Siblings (By Age) #

For young children, look for picture books about siblings with health differences, like “My Brother is Very Special.” Ask your librarian to help find age-appropriate titles. For middle grade readers, books like “The One and Only Bob” and “Wonder” normalize difference and build empathy in ways that feel natural rather than preachy. For teens, fiction that opens conversations about illness, loss, and resilience, books like “The Fault in Our Stars,” can be a starting point for the kinds of conversations that are hard to begin from scratch.

One more resource that came directly from our family’s experience: our picture book Corbin and the Helpers Inside His Body was written for children with sJIA, but siblings have found it just as valuable. It gives them the vocabulary to understand what their brother or sister is going through, in a way that is honest without being scary.

The sibling who grows up alongside a child with sJIA often develops extraordinary empathy, flexibility, and resilience. The hard days shape them too, and not always in the ways we fear. Your job is to make sure they feel as loved and seen as their brother or sister.
