Preparing Your Firstborn To Be An Older Sibling

Introducing a new sibling is such a special and tender season for your family — but let’s be honest, it can feel a little like navigating uncharted waters, too!

Your sweet firstborn has had your full attention their entire life — whether that’s been a short 18 months or seven whole years, like my oldest daughter. No matter how long they’ve been your “one and only,” welcoming a new baby is a big adjustment for everyone. There’s a period of learning, growing, and shifting as everyone settles into their new roles.

The good news? A little bit of preparation can go a long way when it comes to helping your older child adjust to this big change. (And you’re already on the right path just by reading this blog!)

How to Start Preparing for Introducing a New Sibling

Let’s talk specifics: What can you do now to prepare your older child for the arrival of their new baby brother or sister? Here are my tried-and-true tips — both as a photographer and as a mom who’s walked this road myself.


1. Read Books About Becoming a Big Sibling

One of the sweetest ways to begin preparing your child for introducing a new sibling is through books. Stories help children process change in a safe and familiar way.
A few favorites to start with:
 I’m a Big Sister or I’m a Big Brother by Joanna Cole
 The New SmallCircles – Unusual Relationships for Unique People by Tess Castleman

These books gently walk through the ups and downs of welcoming a new sibling and help little ones imagine what this new season might look like.

2. Let Them Be Involved in Preparing for Baby

As you decorate the nursery or shop for those tiny newborn essentials, invite your older child to help! Let them choose a special stuffed animal or pick out a piece of décor for the baby’s room. Giving them small, meaningful opportunities to participate helps them feel included and important — not left out of all the excitement.


3. Use Inclusive Language: “Your Baby”

I once heard Dr. John Delony share this tip, and I’ve never forgotten it. Instead of always referring to the new addition as “the baby,” try saying “your baby.”
For example: “Your baby is going to be so lucky to have you as a big sister!”
That small shift in language can make a big difference in helping your child feel connected, protective, and proud of their new role.


4. Be Thoughtful About Their First Meeting

That very first meeting between big sibling and baby is such a tender, once-in-a-lifetime moment. If possible, have Dad or another family member hold the baby when your older child enters the room, so your arms are free to scoop up your big kid for a snuggle first. This can help reassure them that their bond with you is still strong and steady, even as everything around them feels new.

5. Don’t “Blame” the Baby

It’s natural for older siblings to notice the shift in your attention once the baby arrives. That’s why it’s so important to be mindful of how you explain changes.

Try to avoid saying things like:
“I can’t get your snack because I have to feed the baby.”

Instead, try language like this:
“Of course! I’d love to help you. I just need a few minutes, and then I’ll be right there.”

This gentle shift helps prevent your older child from seeing the baby as the reason their needs aren’t being met, which can minimize resentment and help preserve harmony in those early days.


6. Involve Them After Baby Arrives

Once baby is home, inviting your older child to help in small ways can build connection and confidence. Maybe they can pick out the baby’s outfit, sing a lullaby, or talk to the baby during tummy time. These tiny moments help strengthen their sibling bond and remind them they’re a valued, important part of this new family dynamic.


7. Prioritize One-on-One Time

Even with all the excitement of introducing a new sibling, it’s natural for feelings of jealousy or insecurity to pop up. One of the best ways to reassure your firstborn of their place in your heart is to carve out a little one-on-one time.

It doesn’t need to be elaborate — think movie nights, a quick ice cream date, or a special walk together. What matters most is giving them your undivided attention and reminding them that while everything around them is changing, your love hasn’t.


8. Keep Their Routine as Consistent as Possible

Children thrive on predictability. As much as possible, try to maintain familiar routines: bedtime stories, silly dinnertime traditions, the way you brush their hair in the morning. These little rhythms provide a sense of security and normalcy in the midst of big transitions.

Final Thoughts on Introducing a New Sibling

Every child will react differently to becoming a big sibling — some with excitement, others with hesitation, and most with a little bit of both. The most important thing you can offer is your steady presence, your patience, and your reassurance that there’s room in your heart for them and this new little life.

I hope these tips help make introducing a new sibling a little smoother for your family. If you’re looking for a photographer to beautifully capture those first tender moments between your big kid and their new baby sibling, I would love to help you preserve those memories.
