Peaceful Parent, Happy Siblings

If you're exhausted by the fighting, the bickering, the "it's not fair" — you're not alone.

If you have more than one child, you’ve probably seen moments like these:

• “I can’t even drive safely—they can’t keep their hands off each other.”

• “She loves her brother... but her hugs somehow turn into choking.”

• “I came out of the shower and realized he had peed on the baby.”

Some days, it can feel relentless—like you’re constantly refereeing and trying to keep everyone safe. If this sounds familiar, you’re not alone.

Sibling conflict is natural. Young children are wired to compete for your time and attention, and they don’t yet have the skills to manage big emotions or work things out peacefully. But without support, those patterns can take hold and erode the closeness you want your kids to share.

But here’s the good news:

The sibling relationship is one of the most powerful places children learn emotional intelligence, empathy, and lifelong relationship skills.

And parents can make a tremendous difference in shaping that relationship.

Even if your children are already struggling, it is absolutely possible to help them move toward a more peaceful, respectful connection.

Imagine your children:

  • • Working things out instead of escalating.
  • • Laughing together more than fighting.
  • • Standing up for themselves without hurting each other.
  • • Feeling secure enough that they don’t have to compete for your love.

That kind of relationship doesn’t happen by accident.

But with the right support, it grows—day by day. Peaceful Parent, Happy Siblings shows you a different path—one where siblings learn to work things out, advocate for themselves, and become real sources of comfort and support for each other.

Less drama, more love

“This book completely changed the dynamic between my three children. If you have more than one child, get your hands on this book.”

What makes this book different?

Most parenting advice focuses on stopping fighting in the moment. This book helps you change the dynamic between your children.

You'll find real scripts, step-by-step coaching tools, and strategies that actually work—even for children who seem temperamentally mismatched.

Peaceful Parent, Happy Siblings

You’ll learn how to:

  • • Regulate your own emotions so you can stay calm in hard moments. You create a calmer home—and your children learn from your modeling.
  • • Stay deeply connected with each child—even while setting limits. When each child feels secure with you, they feel less need to compete—and more ability to connect.
  • • Coach your children to express feelings, solve problems, and repair after conflict. You can use conflict as an opportunity to teach emotional intelligence, problem-solving, and lifelong relationship skills.

What parents are saying

Just fantastic!! The book gets better with every chapter! Loved the 7 categories of bickering and the concept that fighting can be a GOOD thing because it teaches conflict resolution and problem solving. LOVE the section on apologizing. LOVE all the scripts!! What a great coach Dr. Laura is...she really understands the challenges of being a parent and gets what we go through!

- Stacy

I am a SAHM to two boys, ages 4 1/2 and 18 months. I first found Dr. Markham when my youngest was about 10 months old and some major sibling issues reared their ugly head. I cannot say this enough: Her book, "Peaceful Parent, Happy Siblings" was a LIFE CHANGER. I couldn't believe the incredible results I got from putting her advice and strategies into action. I put if off because I was too darn tired from sleepless nights to take on the task of reading another book. But the beauty of this book is that the layout of it makes it possible to start immediately. I highly recommend it.

- Christina Peck

Peaceful Parent, Happy Kids is invaluable. But Peaceful Parent, Happy Siblings takes it to the next level and makes it all come alive so vividly. The scripts are so helpful and make it all so real. There's a great overview/explanation of how family emotions work and how you, as the parent, are the model and coach. I love the list of what children learn when parents allow the child's feelings and respond with empathy! This book is absolutely phenomenal!

- Beth

My older child was so angry about the new baby—she would lash out and even try to hurt him. I felt like I had to watch them every second. Using the approach in this book changed everything. As she felt more secure, her behavior completely shifted. Now she’s gentle, helpful, and even affectionate with her baby brother.

- Lakshmi

Shout out to Dr Laura Markham for transforming my kids' relationship, with her book Peaceful Parent, Happy Siblings!
