Sibling Rivalry: Free Milestone Moment Guide

One minute they’re laughing together. The next, someone is yelling, “That’s not fair!”

Sibling conflict is a normal part of growing up together—but that doesn’t make the constant grabbing, competing, tattling, teasing, arguing, and comparing any less exhausting for parents.

This free Sibling Rivalry Milestone Moment guide gives you a simple introduction to what may be happening underneath those conflicts and how you can begin helping your children build healthier ways to handle them.

Designed for families with children from 12 months through age 16, this guide helps you look beyond simply stopping the fight and begin strengthening the relationship skills children will use throughout their lives.

Inside This Free Guide, You’ll Find:

• A parent-friendly look at why sibling rivalry happens
• Reassurance about what sibling conflict can look like as children grow
• An introduction to the Emotional Muscles children use during sibling conflict
• Practical ideas for responding to disagreements with more confidence
• A sample of the simple activities included in the full guide
• A sample of our curated children's book recommendations for exploring sibling relationships through stories

Sibling rivalry is not about raising children who never disagree.

It is about helping them gradually learn how to communicate, wait, respect boundaries, handle jealousy, solve problems, and reconnect when things go wrong.

And you don’t have to teach all of that at once.

Start with one idea. Practice it together. Build from there.
