Helping Your Toddler Adjust to a New Sibling: Gentle Strategies That Work

Welcoming a new baby into the family is a joyful occasion—but for your toddler, it can be a confusing and even upsetting time. Their world is about to shift, and they may not fully understand why.

The good news? With the right approach, you can help your toddler not only adjust to their new sibling, but also thrive in their new role as a big brother or sister.

🧠 Understanding the Toddler Perspective

Toddlers are creatures of routine and predictability. A new baby can feel like an invasion of their safe world—and suddenly, their parents’ attention is being divided.

Common toddler reactions may include:

  • Regression (e.g., wanting a dummy again or accidents after potty training)
  • Tantrums or clinginess
  • Jealousy or withdrawal
  • Curiosity mixed with frustration

👣 Before Baby Arrives: Laying the Groundwork

1. Involve Them in the Pregnancy
Let them help decorate the nursery, pick out clothes, or listen to the baby’s heartbeat. Talk about the baby using “our baby” language to build connection.

2. Read Books About New Siblings
Stories help toddlers make sense of big changes. Try:
📖 “I Am a Big Brother” / “I Am a Big Sister” by Caroline Jayne Church
📖 “The New Baby” by Mercer Mayer

3. Set Expectations Gently
Talk about what babies do (cry, sleep, feed), and how they won’t be playmates right away—but they will be loved by everyone, including their big sibling.

👶 After Baby Arrives: Easing the Transition

1. Keep Routines Steady
Maintain your toddler’s usual bedtime, meals, and playtime. Predictability helps them feel secure amid change.

2. One-on-One Time
Even 10 minutes of undivided attention each day makes a huge impact. Play their favourite game, go for a walk, or cuddle during a story.

3. Let Them Help (When They Want To)
Ask your toddler to bring a diaper, choose the baby’s outfit, or sing a lullaby. Feeling involved boosts their sense of importance.

4. Avoid Comparisons
Resist saying things like, “You were such a quiet baby!” Instead, affirm their unique role: “You’re such a kind big sister.”

💞 Handling Tough Emotions

Validate Their Feelings
“It’s okay to feel sad or mad sometimes. It’s a big change.”

Create a Safe Space for Expression
Use play, drawing, or toddler-friendly emotion cards to help them express what’s going on inside.

Give Words to Their Experience
Try: “You miss having Mommy all to yourself. That makes sense. I love you just as much now as before.”

🎉 Celebrating the Big Sibling Role

Make a fuss—in a good way! Ideas include:

  • A “Big Sibling” gift from the baby
  • A badge or t-shirt they can wear proudly
  • A special activity day with one parent or grandparent

📝 When to Seek Extra Help

If your toddler’s adjustment becomes extreme (aggression, prolonged withdrawal, severe regression), don’t hesitate to speak to a paediatrician or child psychologist. Early support can ease transitions for everyone.

🌈 Final Thoughts

Your toddler’s world is changing—but your love isn’t. With patience, empathy, and reassurance, you’re helping them build the foundation for a lifelong sibling bond. It won’t always be easy—but it will be worth it.

You’ve got this, mama. 💪
