My sister and I had a good relationship growing up, but I’d say we’ve grown even closer as adults. What does it take to make that happen? I’ve been reflecting on that lately, thinking about the habits that helped us stay connected, and what I’ve noticed in other sibling pairs who seem to genuinely enjoy each other’s company.
I don’t think it’s about being exactly alike, or never arguing—that’s unrealistic for any siblings, no matter how close they are. What stands out to me instead are the small, everyday choices that add up to a real sense of loyalty, trust, and respect. Great sibling relationships aren’t just a matter of luck; they’re built over time, through intentional effort.
I wanted to share some of the habits I’ve seen (and tried to practice myself) that seem to make all the difference. Whether you’re working to repair a strained sibling dynamic or just hoping to keep a good one strong, these are the things I believe help turn a family bond into a lifelong friendship.
1. Share the little things in life
Deep connections aren’t just built on big, life-changing conversations. They’re formed in the small, everyday moments. A funny meme, a random thought, a quick “this reminded me of you” message—these tiny interactions create a sense of ongoing connection. It’s easy to assume your sibling doesn’t care about the small stuff, but often, those are the moments that keep relationships feeling fresh and close. Even if life gets busy, a simple text or a quick check-in can remind your sibling that you’re thinking about them.
2. Celebrate each other’s wins without jealousy
Sibling rivalry is common, but it doesn’t have to define your relationship. The healthiest siblings learn to cheer each other on without comparison. If your sibling gets a promotion, buys a house, or achieves a personal goal, make a big deal out of it. Send a congratulatory message, take them out to celebrate, or simply tell them how proud you are. When you shift from competition to teamwork, your bond strengthens. A win for them isn’t a loss for you—it’s a reason to celebrate together.
3. Defend each other in public, discuss differences in private
Disagreements are inevitable, but how you handle them makes all the difference. Strong sibling relationships have an unspoken rule: always back each other up in public, even if you have personal differences. If someone criticizes your sibling, stand up for them. If a disagreement arises, address it privately rather than calling them out in front of others. This habit creates a sense of security, knowing that no matter what happens, you have each other’s backs when it really counts.
4. Know and respect each other’s love languages
Not everyone shows or receives love in the same way. Some siblings express affection through words, while others prefer quality time or acts of service. Pay attention to how your sibling naturally expresses care—do they offer advice, help out with tasks, or give thoughtful gifts? Once you understand their love language, you can reciprocate in a way that resonates with them. Meeting each other’s emotional needs in a way that feels natural to them (rather than just to you) can make your relationship feel more fulfilling.
5. Apologize quickly and sincerely
No matter how close you are, mistakes will happen. You’ll say the wrong thing, forget something important, or unintentionally hurt their feelings. The key to a strong sibling bond is learning to own up to your mistakes without making excuses. A genuine, “Hey, I was wrong and I’m sorry,” goes a long way in preventing resentment from building up. The quicker you address an issue, the easier it is to move forward. And when your sibling apologizes to you? Accept it with grace—no one likes feeling like they’re permanently in the wrong.
6. Create traditions that are just for you
Life pulls siblings in different directions, but shared traditions help keep you connected. Maybe it’s a yearly siblings-only trip, a movie night when you’re all in town, or a birthday tradition that’s uniquely yours. These rituals create a sense of continuity, even when your lives get busy. Having something to look forward to—no matter how small—keeps your bond strong over the years. And the best part? These traditions don’t have to be grand or expensive; it’s the consistency that makes them meaningful.
7. Be curious about each other’s lives
People change, and siblings who stay close are the ones who make an effort to keep up. Ask questions about their work, their hobbies, their struggles, and their wins. Show genuine interest in the things they care about, even if they’re different from your own interests. When you treat your sibling as someone you’re still getting to know rather than someone you already have figured out, your relationship stays dynamic and engaging. A little curiosity goes a long way in keeping your connection fresh.
8. Offer support without strings attached
One of the most valuable things a sibling can offer is unconditional support. Whether your sibling needs a loan, a place to crash, or just someone to vent to, showing up without keeping score strengthens your bond. Support should never feel transactional—when you help out, do it because you genuinely want to, not because you expect something in return. When both siblings operate this way, it creates an environment where you can rely on each other without guilt or obligation.
9. Let each other be different
It’s natural to want your sibling to see the world the way you do, but the strongest relationships thrive on mutual respect for differences. Maybe one of you is introverted and the other thrives in social settings. Maybe you have different political beliefs, parenting styles, or life goals. The key is accepting each other for who you are, without trying to change or “fix” one another. When you embrace your sibling’s individuality instead of resisting it, your bond deepens.
Sibling relationships are some of the longest-lasting connections in life, but they don’t stay strong automatically. They require effort, understanding, and a willingness to grow together over time. Even if your relationship isn’t perfect, practicing these habits can bring you closer and create a bond that lasts a lifetime. Why not start today?
