Supporting Healthy Sibling Conflict

Ms. Lina

With a calm presence and consistent boundaries, children can turn sibling squabbles into opportunities for connection and maturity.

During summer break, many families find themselves spending more time together - and that often means more opportunities to witness sibling conflict up close. At AIMS, where so many of our families have older and/or younger siblings, these moments are a natural part of daily life.


As both a Montessori educator and a mom of two, I know firsthand how challenging (and surprisingly productive!) sibling disagreements can be. While they might sound loud or look messy, these moments are powerful opportunities for children to develop essential life skills.


In Montessori, we believe sibling conflict is not only normal, it’s also healthy. Just like in the classroom, where children take turns talking and listening with care (see our earlier Peace Rose blurb), the home environment can be a space for respectful problem-solving and emotional growth.


Instead of stepping in as the referee, consider taking on the role of a calm, neutral guide. Ask yourself:

  • Are both children safe?
  • Is this a moment where they might learn something through the conflict itself?
  • Can I support without solving?


Here are some age-appropriate strategies:


Toddlers (18 mo – 2.5 yrs)

  • Use simple, clear language: “You want the toy. Your brother has it. Let’s wait.”
  • Offer alternatives or distraction rather than forced sharing.


Preschoolers (3–6 yrs)

  • Narrate neutrally: “It looks like you both want the same puzzle.”
  • Introduce visual tools like a timer or turn-taking object (e.g., Peace Rose or a talking stick).


Lower Elementary (6–9 yrs)

  • Encourage “I” statements: “I felt left out when you didn’t let me join.”
  • Ask guiding questions: “What’s a fair solution for both of you?”


Upper Elementary (9–12 yrs)

  • Reflect after the moment: “What worked? What could you do differently next time?”
  • Invite collaboration: “Can you come up with a solution together?”


With a calm presence and consistent boundaries, children can turn sibling squabbles into opportunities for connection and maturity.


As Maria Montessori once said: “Character formation cannot be taught. It comes from experience and not from explanation.”

Buddy classrooms are where students from different classrooms regularly come and go to work and learn together in shared spaces throughout the school. In this setup, they interact with one another, creating a more dynamic and collaborative environment. We also have mixed ages inside the classroom, which allows younger and older students to learn from each other, build relationships, and develop important social and leadership skills.  In a Montessori environment, one of the most powerful and unique aspects of learning is the natural collaboration that occurs between children of different ages. Unlike traditional classrooms that separate students strictly by grade, Montessori classrooms are intentionally designed to foster connection, mentorship, and shared discovery. At AIMS, this philosophy comes to life in meaningful and inspiring ways as older children regularly work alongside younger ones, whether through reading together or demonstrating classroom materials, often referred to as “works.” When older children read to younger students, the experience goes far beyond simple storytelling. For the younger child, it provides a model of fluent reading, builds listening skills, and nurtures a love for language. There is something deeply engaging about hearing a story from a peer: it feels accessible, relatable, and exciting. Younger students often look up to older ones, and this admiration naturally increases their motivation to learn and grow. For the older child, the benefits are equally significant. Reading aloud strengthens comprehension, fluency, and confidence. It also requires patience and awareness, as they adjust their pace and tone to meet the needs of their younger audience. In these moments, older students step into a leadership role, developing empathy and a sense of responsibility. They begin to see themselves not just as learners, but as contributors to their community. Another beautiful aspect of this cross-age interaction at AIMS is when older children present works to younger students. These demonstrations might include showing how to use a specific material, explaining a concept, or guiding a younger child through a hands-on activity. For the younger child, this peer-led introduction can feel less intimidating than adult instruction. It encourages curiosity and invites them to explore new challenges with confidence. Meanwhile, the older child deepens their own understanding by teaching. Explaining a concept requires clarity of thought and reinforces their knowledge in a lasting way. It also cultivates pride and ownership in their learning journey. They begin to recognize that mastery is not just about completing a task, but about being able to share it meaningfully with others. At AIMS, these interactions are not forced, they grow organically within a carefully prepared environment. Teachers guide and support the process, ensuring that each child is both challenged and nurtured. The result is a vibrant community where collaboration replaces competition, and learning becomes a shared experience. Ultimately, the relationship between older and younger children in a Montessori setting reflects a broader life lesson: we learn best when we learn together. Younger children gain inspiration, guidance, and confidence, while older children develop leadership, empathy, and a deeper understanding of their own abilities. It is a dynamic, reciprocal process that enriches everyone involved, and it is one of the many ways AIMS creates a truly meaningful educational experience.

“To confer the gift of drawing, we must create an eye that sees, a hand that obeys, a soul that feels; and in this task, the whole life must cooperate. In this sense, life itself is the only preparation for drawing. Once we have lived, the inner spark of vision does the rest.” –Maria Montessori
