For siblings of children and adults with 5p- Syndrome — and for the parents who are raising them alongside each other. Your experience matters here too.
The sibling experience changes as children grow. What a 6-year-old needs to understand is very different from what a teenager or young adult is working through.
Children ages 5–8 are concrete, literal thinkers. They notice differences clearly but interpret them through their own lens: "Why does she get to skip the dentist waiting room?" "Why do people always look at us?" "Why does he make that sound?"
At this age, simple, honest, age-appropriate explanations work best. Children do not need the full medical picture — they need enough information to make sense of what they observe. Gaps in explanation get filled with imagination, which is often worse than reality.
Young siblings also need permission to have ordinary feelings: "It's okay to feel mad that we had to leave the party early." Validating feelings is not the same as agreeing that the situation is unfair — but it is essential.
"Your brother's brain works a little differently than yours. That's why he does some things differently — and why he goes to extra appointments. He loves you the same way you love him, just in his own way."
Between ages 9 and 12, children become more socially aware and peer relationships take on enormous importance. This is when the social complexity of having a sibling with a disability becomes most visible — and most painful.
Tweens may experience embarrassment in public situations and then feel deeply guilty about it. They are old enough to understand more about the permanence of 5p- and may begin asking harder questions about the future: "Who will take care of him when you're old? Will that be me?"
This is also when parentification risk increases — tweens are capable enough that parents may lean on them more than is healthy. It is worth being explicit: "It is not your job to care for your sibling. That's our job."
Practice these with your tween: "My brother has a chromosomal condition — it means his brain works differently. He's pretty awesome actually." Having a practiced, confident response reduces anxiety about unexpected moments.
SibShops are workshops for siblings of children with special health and developmental needs. They blend fun activities with opportunities to meet other siblings in a peer group setting. Finding out other kids have similar experiences is often transformative. Search sibshops.org for local programs.
Adolescence is fundamentally about building an individual identity separate from the family. For siblings of someone with 5p-, this developmental task is complicated by loyalty, guilt, and the genuine ways their family life is different from most of their peers.
Many teen siblings report choosing activities, friendships, and eventually career paths influenced by their sibling. Some feel called toward caregiving professions. Others actively separate themselves. Both responses are valid. The goal is that the choice is theirs, not assumed.
Teens also often take on invisible emotional labor — managing family dynamics, mediating between parents, translating for their sibling. This can build empathy and resilience, and it can also be a genuinely heavy burden. Check in explicitly.
Teens need to hear explicitly that future caregiving is a choice, not an obligation. "We are making plans so that you will not be responsible for your sibling's full care. Your relationship with her will always matter, but that is different from being her primary caregiver." Silence on this topic breeds anxiety.
The Five P- Society offers scholarships for siblings applying to post-secondary education. See the dedicated section below. Teen siblings should know this resource exists as they begin college planning.
For adult siblings, the relationship with a brother or sister with 5p- takes on new dimensions. As parents age, questions about future planning become urgent. Adult siblings may step into advocacy roles, legal guardianship, or serve as primary supporters — or they may not, by choice or circumstance.
Adult siblings often describe a complicated mixture of love, pride, grief, and occasional resentment that coexists throughout their lives. Many report that their sibling fundamentally shaped their values, career choices, and capacity for empathy — and that they would not change that, even when they wish things were different.
The Sibling Leadership Network (SLN) is the national organization focused specifically on adult siblings of people with disabilities — offering peer support, policy advocacy, and resources for estate and future planning.
Sibling Leadership NetworkAdult siblings are often included in special needs trust planning, guardianship decisions, and residential planning. If you are in this position, start the conversation with your parents early. The Arc's Future Planning resources and a special needs attorney are good starting points.
The Five P- Society hosts a private online community for adult siblings. These are spaces to process the unique experiences of adulthood alongside a sibling with 5p- — career decisions, relationship dynamics, caregiver transitions — with people who actually understand.
No parent intends to sideline a sibling — but the demands of caring for a child with significant needs make it easy to happen. These four things make the biggest difference.
Tell your child explicitly: "It's okay to feel frustrated, embarrassed, sad, or even angry sometimes. All of those feelings are typical and they don't make you a bad person. You can talk to me about them." Children who know their feelings are welcome are far less likely to bury them.
Even 30 minutes of undivided attention — no phones, no talk about the sibling — communicates that this child is fully seen and valued on their own terms. It does not need to be elaborate. It needs to be consistent and genuinely theirs.
Children handle information better than uncertainty. When a sibling is scheduled for surgery, starting a new medication, or transitioning to a new school, tell your other children age-appropriate versions of what is happening. Being excluded from family information breeds anxiety.
Parentification happens when a child takes on caregiver responsibilities — emotional or physical — beyond what is developmentally appropriate. Signs include a sibling who suppresses their own needs, mediates parental conflict, or feels responsible for their sibling's wellbeing. Check in explicitly: "Your job is to be a kid."
"Growing up with Caleb made me someone who notices people. I see who gets left out of a conversation, who needs an extra minute. I don't think I'd be the same person without that. I also spent a lot of years wishing we were a 'typical' family — and a lot of years feeling guilty for wishing that. Both are true at once."
"I didn't know other siblings felt what I felt until I went to my first SibShop at age 12. There was this moment in the room where I thought — these kids actually get it. I wasn't weird. I wasn't ungrateful. I was just a kid with a complicated situation, same as everyone else in that circle."
SibShops, developed by Don Meyer at the Sibling Support Project, are the gold standard for peer support among siblings of people with special needs. They blend fun, recreational activities with peer discussion led by trained facilitators. The goal is not group therapy — it is community. Siblings leave knowing they are not alone.
SibShops exist in all 50 states and in more than a dozen countries. They serve children ages 8–13, with some programs extending to teens. Online SibShops are also available for families without a local program.

A brief note to the teacher at the start of the year can be helpful: "Our family has a child with 5p- Syndrome (a chromosomal condition). Our other child, [name], may occasionally seem distracted or have questions about family situations. We wanted you to have that context." School counselors are often excellent supports for siblings — a proactive introduction before any crisis is much easier than reaching out in a difficult moment.
It depends on the nature and extent of the caregiving. A sibling who genuinely enjoys engaging with their brother or sister and helps naturally is different from one who feels responsible for their sibling's wellbeing, suppresses their own needs, or becomes anxious when they cannot help. Have a direct conversation: "I notice you often look after your brother. I want you to know that's not your job — we are grateful for your kindness, but you should not feel responsible." Then watch whether the behavior continues or changes.
First, validate what your child is feeling — it is painful to see someone you love mocked. Then work together on language they feel comfortable using. "That's my sister and she's not interested in being a joke" is simple and firm. Role-playing with your child before these situations happen reduces the panic in the moment. If the behavior is happening in a school setting, it may be worth a conversation with the teacher. Your child should never feel they have to manage this alone.
Yes, and it is often not a one-time event. Siblings may grieve at different developmental stages as they come to understand more fully what their sibling's condition means for the long term. A 10-year-old who realizes their sibling will probably never drive, live alone, or have children of their own may need to process this very differently than they did at age 5. These are genuine losses — of the sibling relationship they might have had, of a certain vision of their family's future. They deserve acknowledgment, not minimization.
Our private sibling community — on Facebook and through our member network — connects siblings of all ages. Because "no one else gets it" should never be true.
