Preparing Siblings for a New Baby: Helping Big Brothers and Sisters Feel Ready and Loved

Welcoming a new baby is an exciting time — but if you're already a parent, your heart isn't just thinking about the newborn. It's also thinking about your other little one(s), and how they’ll adjust to this big change.

Whether your child is a toddler, preschooler, or older, becoming a sibling is a huge transition. The good news? With gentle preparation and a little creativity, you can help them feel involved, included, and still just as special.

Here’s how to prepare your child for their new role as big brother or sister:

1. Start the Conversation Early (and Honestly)

Even young children pick up on changes. Start talking about the baby as soon as you feel ready — and use clear, simple language.

You might say, “There’s a baby growing in Mommy’s belly,” or “You’re going to be a big brother — that means helping and loving the baby.”

Let them ask questions. Answer with honesty and warmth, even if they ask things like, “Will you still love me?”

2. Read Sibling-Themed Books Together

Books are a beautiful, non-scary way to introduce new concepts.

Some favorites:

• “I’m a Big Sister” / “I’m a Big Brother” by Joanna Cole

• “The New Baby” by Mercer Mayer

• “Hello in There!” by Jo Witek

Reading together also creates calm, focused moments to bond.

3. Let Them Be Part of the Preparation

Kids love being included. Let them:

• Pick out a toy or onesie for the baby

• Help decorate the nursery

• Pack a small “gift” to give the baby at the hospital

And don’t forget: a small gift from the baby to the sibling is a sweet way to start their relationship with love.

4. Talk About the Plan — and What Will Change

Children feel safer when they know what to expect. Talk through:

• Who will take care of them when you go to the hospital

• Where the baby will sleep

• How routines might change (but how they will still have their special time too)

Use visual tools like calendars or drawings if they’re very young.

5. Reassure, Reassure, Reassure

The biggest fear for many kids? Losing your attention or love.

Remind them often: “My heart is big enough for both of you,” or “Even when I’m holding the baby, I’m always your mama too.”

You might set up a special “just us” time each day, even if it’s just five minutes of cuddles or a bedtime story.

6. Let the Feelings Be Messy

Excitement, jealousy, confusion, pride — it’s all valid. Your child may act out, regress, or seem indifferent. That’s okay.

Acknowledge their feelings without judgment. Say things like, “It’s okay to miss having me to yourself” or “You can always talk to me about how you feel.”

7. After Baby Arrives: Keep the Bond Strong

• Invite them to help in age-appropriate ways (like handing you a diaper)

• Show appreciation: “Thank you for being such a kind big sister.”

• Try to protect their one-on-one time with you — even just a short daily walk or game

You’re not dividing your love — you’re multiplying it. And they’ll feel that.

Final Thoughts: A Growing Family Means Growing Love

Preparing your child for a new sibling is more than logistics — it’s about holding space for their feelings, keeping their world steady, and reminding them that your love is always theirs.

And when you see your little one reach out to hold the baby’s hand, or whisper a giggle into the crib — you’ll know you’re doing just fine.
