By the numbers

What research tells us about siblings.

Siblings

62studies on siblings of people with mental health conditions were brought together in a 2023 review.
3,744siblings took part in those studies, from many countries (2023 review).
Mildwas the average level of depressive symptoms siblings reported. Siblings of people with schizophrenia-spectrum conditions reported more.

Families

21%of U.S. children aged 3 to 17 had ever been diagnosed with a mental, emotional or behavioural health condition (2021). Many have brothers and sisters.
23.1%of U.S. adults lived with a mental health condition in 2022.

Why siblings are often missed

Siblings matter, and their needs are often missed.

Siblings are often the “forgotten” family members. A large 2023 review of 62 studies found that siblings of people with mental health conditions often grieve the relationship they used to have, and feel their own needs come second.

The same review found siblings feel most vulnerable when an illness first starts and when it comes back. Not understanding what’s going on, and families not talking about it, made things harder.

This guide can’t diagnose your sibling. If you’re worried, encourage them to talk to their clinical provider or therapist, or talk to a parent or trusted adult.

Siblings’ hidden needs

The “easy” child may be struggling quietly.

Research describes siblings who try to be the “well” one: working extra hard, growing up fast, or acting as the family’s comforter or go-between. Relatives may ask about the unwell sibling and forget to ask about them.

🏅 The “good” childTrying not to add to the family’s worries.
Read more

Some siblings work hard to be no trouble at all. They hide bad grades, sad days or their own worries. From the outside they look fine. Inside, they may feel alone.

🎒 Growing up fastTaking on adult jobs too early.
Read more

Siblings may cook, babysit, calm arguments or keep an eye on their brother or sister. Research describes siblings feeling they had to make up for the illness.

See the “Growing up too fast” guide for more.

🌀 Guilt“Did I cause this? Could I make it worse?”
Read more

Some siblings feel guilty, wondering if they caused the illness or could make it worse. Others feel guilty for being well. You did not cause your sibling’s struggles.

🔀 Go-betweenStuck in the middle of family arguments.
Read more

Siblings can end up carrying messages, keeping secrets or calming everyone down. It’s okay to step back and say, “I love you both, but I can’t be in the middle.”

Your own feelings

Anger, worry, jealousy and grief are all normal.

You might be angry at how much attention your sibling gets, then feel guilty for being angry. You might worry it could happen to you. Siblings in research also describe positives: more compassion, closer bonds and gratitude. Both can be true.

🕯️ GriefMissing the sibling you used to know.
Read more

Many siblings grieve the relationship they used to have, even though their brother or sister is still here. That grief is real, and it can come and go.

🧬 Worry about yourself“Could this happen to me?”
Read more

It’s common to wonder whether you’ll go through something similar. If this worry is on your mind, talk to a clinical provider or counsellor. They can help you understand your own health without guessing.

🌻 Good things tooCompassion, closeness and gratitude.
Read more

Siblings in research also describe positives, like more compassion, closer bonds and gratitude.

Use the “My sibling feelings check-in” worksheet to name what you’re feeling and who you can talk to.

What helps your sibling

Be a brother or sister first.

You know your sibling in a way doctors don’t: shared jokes, memories and history. That makes you a powerful source of normal life. Keep inviting them to things, even if they say no sometimes, and remind them who they are beyond the illness.

🎮 Everyday connectionLow-pressure time together.
Read more
  • Do low-pressure things together: a walk, a game, a show
  • Send a meme or a memory, with no need to reply
  • Text about everyday stuff, not just how they’re feeling
🛡️ Stick up for themPush back on hurtful comments.
Read more

Stick up for them when others make hurtful comments. SAMHSA encourages people to help others understand the facts about mental health so they don’t discriminate.

🧭 Back up the planSupport, rather than take sides.
Read more

Back up your parents’ or your sibling’s care plan, rather than taking sides in arguments. Offer one specific help, like a ride to an appointment.

🆘 Never keep a dangerous secretSafety comes before loyalty.
Read more

If your sibling tells you they want to hurt themselves or someone else, tell a trusted adult or call or text 988. It isn’t betrayal. It’s care.

See the “Helping someone who may be suicidal” and “Supporting someone who self-harms” guides.

Talking with your sibling

Honest, kind and one thing at a time.

NAMI says good communication is largely about habits. Get the person’s attention first, cover one topic at a time, say exactly what you mean, and ask for their ideas too.

🗝️ Opening upStart with care, not a lecture.
Read more
  • “I’ve missed hanging out. Want to grab food this week?”
  • “I’m not here to fix anything. I just want to know how you are.”
  • “You don’t seem like yourself. I’m here if you want to talk.”

SAMHSA suggests letting someone know you care, asking questions and listening to their ideas.

🔥 When it gets heatedIt’s okay to take a break.
Read more

Old sibling patterns can flare up fast. Use “I” statements (“I feel worried when you don’t answer”), and agree that either of you can pause and come back later.

❓ Ask what they needThey know best what helps.
Read more

Ask what helps on hard days, and what makes things worse. Some people want company; others want space and a quiet check-in.

If you’re a kid or teen

It’s not your job to fix it, and you deserve support too.

When your brother or sister is struggling, home can feel tense, scary or sad. You might feel ignored, embarrassed or jealous. All of that is normal, and none of it makes you a bad person.

🧑‍🏫 Talk to someoneA parent, relative, teacher or school counsellor.
Read more

Talk to a trusted adult, friend or counsellor about how you feel. You can say, “I know everyone is busy with my brother, but I need some help too.”

⚽ Keep your own lifeYour goals, friends and hobbies matter.
Read more

Keep doing the things you enjoy. Having your own life isn’t selfish. It helps you stay strong, and it shows your sibling that life goes on.

❓ Ask questionsNot knowing is often the hardest part.
Read more

Research found that confusion about what was going on made things harder for siblings. Ask a parent or another adult to explain what your brother or sister is going through, in words that make sense to you.

If you don’t feel safe at home, call or text Childhelp at 1-800-422-4453 (24/7). If you’re in danger, call 911. If you feel really low, call or text 988.

For parents of siblings

A little focused time can go a long way.

NAMI notes that brothers and sisters may resent being pushed aside if all attention goes to one child. Siblings may feel scared, embarrassed, ignored or even blamed.

🧡 What helps siblingsExplain, listen and spend time.
Read more
  • Ask how they are, and really listen
  • Don’t make them a babysitter, messenger or secret-keeper
  • Explain, at their level, what their sibling is going through
  • Spend one-on-one time with each child
🗣️ Talk openlySilence can feel scarier than the truth.
Read more

The 2023 review found that limited communication and confusion about mental illness added to siblings’ distress. Simple, honest explanations, repeated as children grow, help.

👀 Watch the hard momentsOnset and relapse are the toughest times.
Read more

Siblings felt most vulnerable when an illness started and when it came back. Check in with your other children more during those times.

See the “When your child is struggling” guide for more on the whole family.

Looking ahead

Adult siblings often wonder about future care.

As parents age, adult siblings may worry about who will help next. It’s okay to talk about it as a family, ideally with your sibling involved. Plans made early, when everyone is calm, are kinder than plans made in a crisis.

⚖️ What you can offerBe honest about what’s realistic.
Read more

Decide what you can realistically offer, and what you can’t. Offering less, and keeping it up, is better than promising everything and burning out.

The “Sharing the load” worksheet in the “When someone in your family is struggling” guide can help.

📋 Planning with your siblingInclude them in decisions about their life.
Read more

NAMI suggests asking your loved one about a psychiatric advance directive: a legal document they write while well, saying what care they would want if they later become too unwell to decide.

With their permission, ask their providers to speak with you too, so you know the plan and who to contact.

🧺 Sharing it among siblingsOne person shouldn’t carry it all.
Read more

NAMI warns against leaving all the caretaking to one person to “spare” others. If you have several siblings, share tasks based on what each person can manage.

Use the “Planning future care together” worksheet below to start the conversation.

Support & when to get help

Groups for siblings, and who to call in a crisis.

🫂 Family support groupsMany welcome adult siblings.
Read more

NAMI Family Support Groups are for any adult whose loved one has symptoms of a mental health condition, including brothers and sisters. They are led by family members with lived experience, and many meet online.

NAMI Family-to-Family is a free, 8-session class for family members, and DBSA runs groups for friends and family of people living with depression or bipolar.
