Siblings shape our lives like nobody else can. Did you know? We spend over a third of all our free time with them during our childhoods, meaning we’ll see more of our siblings than anyone else during the most important times of our lives. In the process, some of their personalities rub off on us — and vice versa.

No matter how your unique relationship with your siblings develops as you get older, one thing’s safe to say. Your brothers and sisters know you like nobody else does, and that special bond deserves to be highlighted in a unique way.

So, you’ve got touching, hilarious, beautiful, or silly pictures with your brothers and sisters, and you’d love to show them off on Instagram? But you’re not sure how to caption those special snapshots?

We’re here to help! Discover a huge variety of creative sibling Instagram captions for every occasion down below — and get your Control + C and Control + V keys ready!

How to Write Great Instagram Captions for Siblings

Whether you’re shooting for nostalgic, sentimental, deep, savage, or funny sibling captions for Instagram, your messages for and about your brothers and sisters should always hit the right buttons. Aim for captions that highlight the unique sibling bond with a mix of humor and love.

Here are a few tips to get you started — but don’t worry, because not every caption for or about your siblings has to tick every box:

  • Reflect on the special bond you share with your brothers and sisters. Highlight their personality traits, your shared childhood memories, and the things that drive you and your siblings crazy about each other.
  • Not all sibling captions for Instagram have to be funny, but a little humor definitely goes a long way. Brothers and sisters are famous for fighting about silly things but showing up for each other when it really matters. You may want to capture that “savage with a side of love” vibe in your captions!
  • Consider reflecting on shared memories, especially if you are posting throwback photos! Your followers will melt, and your siblings will hopefully have a good laugh.
  • Avoid embarrassing your brothers and sisters on Instagram, unless you know everyone’s up for a laugh and nobody is sensitive about savage captions. When in doubt, don’t post it. Even a simple Instagram caption can complicate sibling relationships for quite a while!

Above all, allow your love for your siblings to shine through when you write Instagram captions about your brothers and sisters! Remember — it’s OK to share inside jokes or post cryptic messages. Your other followers might not understand your references, but they’ll understand that you’re posting about one of the most important relationships in your life.
