How to Prepare Your Older Child for a New Baby: Avoid Jealousy and Build a Sibling Bond

A new baby is one of the happiest events in a family’s life, and one of the biggest changes in an older child’s. If you’re wondering how to prepare your older child for a new baby, you’re probably also wondering how to avoid jealousy, tantrums and that heart-sinking moment when your toddler seems to feel replaced.

We gathered real notes from parents who’ve been through it, from the first weeks with a newborn to families juggling three under four. Their experiences, together with some practical tactics, point to a simple idea: the best way to prevent jealousy isn’t to manage it, it’s to help your children bond before and after the baby arrives.

Why older children feel jealous when a new baby arrives

Toddlers don’t have the words for what they’re feeling, but the feelings are big. One parent described the first weeks after her second child was born as the hardest of her life. She was exhausted and recovering from a C-section, while her son could only see a “replacement” getting all the attention. Another mum brought her second baby home and watched her two-year-old throw the biggest tantrum of his life over something tiny, even after she’d spent over three hours playing with him on the first evening.

From a young child’s perspective, there’s a good reason. Visitors arrive in a steady stream, gifts and cuddles go to the baby, and the grown-ups they relied on suddenly say, “Not now, I’m too tired.” Underneath the tantrum is often a simple fear: am I being replaced?

The good news: it isn’t always hard, and it’s usually a phase

If you’re bracing for the worst, it’s worth knowing that many families have a gentler experience. One parent whose eldest was 18 months old when her sister was born saw no negative changes. The toddler talked more, wanted to help constantly and was proud of her little sister. About a month in, she stopped playing independently for a few weeks and wanted a parent beside her, then went back to happy solo play.

Other parents saw a messier picture. One described a sleep regression, sudden separation anxiety and bursts of screaming over small frustrations, all alongside fierce affection for the baby. The kids wanted to touch and kiss him all the time, and the oldest loved fetching nappies and picking up dummies. Both truths can sit together: your child can adore the baby and struggle with the change.

This is a phase, it will pass.

Shift the goal: from reducing jealousy to building a sibling bond

One parent offered a mindset shift worth keeping: instead of asking how to limit jealousy, ask how to foster a positive sibling relationship. Your children are not just “the first baby” and “the second baby.” They are two people who will be part of each other’s lives long after yours ends.

That reframing changes what you do. Rather than only soothing upset feelings, you create situations where your older child can experience the new baby as someone who comes to love them, not someone who takes love away.

Step 1: Prepare your toddler before the baby arrives

• Build independent play skills. If your child is used to your full attention all day, they’ll feel the change sharply. Gently work up to 10 to 15 minutes of solo play before the due date.
• Choose your words carefully. Say “your baby sister” or “your baby brother” rather than “the new baby,” and introduce words like “family” with simple explanations.
• Tell them what to expect. Walk through their routine once the baby is home: “First we’ll wake up, then cuddle in Mummy’s bed and read a story while Mummy feeds Baby Sister.” It may be the most boring story on the shelf, but predictability calms nerves.
• Make the hospital stay a “special day.” Make sure your child is comfortable with whoever will care for them, and talk about where they’ll go and what they’ll do, not where you’ll be.
• Avoid other big changes. Save potty training, a new bed or a new nursery for before, or well after, the baby arrives.
• Involve them in food. Explain that mums share food to help babies grow, let your toddler help prepare snacks to “share with Baby Sister,” and ask playful questions like, “Do you think Baby Sister likes carrots?” Celebrate their effort in a way that builds pride (“You must be so proud of yourself!”) rather than only saying you’re proud.

Step 2: Create interaction and connection between siblings

Preparation is about calming fears. Bonding is about creating something positive. Give your older child a real role in the baby’s world and a reason to feel proud of it. Helping fetch a nappy, choosing a blanket or “teaching” the baby something are all small ways to say: you matter to this baby, and this baby matters to you.

A shared activity helps even more. A personalised story book that features both children turns the baby from an intruder into a co-star. The personalised sibling book is a gift made for this exact moment, whether it’s given at a baby shower, when you bring the baby home or as a “gift from your new sibling” at the hospital. Reading it together, even before the baby can follow the story, gives your older child a calm, cuddly routine that includes the newcomer rather than excluding them.

Step 3: Protect your older child’s place once the baby is home

One parent’s words capture the spirit: “We chose our words carefully, made it easy for him to earn praise and kept his routine.” A few small phrases make a difference:

And if you’re the exhausted parent reading this, recovering and feeling guilty that you can’t do more, you’re not failing. Tantrums often increase in the first weeks, and parents in our notes said that short, consistent one-to-one time and predictable routines helped more than any grand gesture.

Step 4: Celebrate that everyone is unique

The second half of preventing jealousy is making sure your older child still feels like their own person, not just “the big brother” or “the big sister.” Every child needs to know they are loved for who they are, and that the baby’s arrival doesn’t shrink their place in the family.

One way to show this is through gifts that are clearly theirs. When you buy for both children, choose personalised gifts that reflect each child’s own interests and personality rather than matching sets. For a curious toddler who loves imagining what they’ll be, the Dream Job Sticker Book is a creative activity they can do alone or with you, which also helps build the independent play skills mentioned earlier. For a child who loves adventure, a personalised travel adventure book lets them star in their own story exploring the world.

The message to your children is the same, whether they’re three or thirty: you’re different, you’re both loved, and you’re both special.

Frequently asked questions

How do I prepare my toddler for a new baby?

Start a few weeks before the birth. Explain what will happen in simple terms, use words like “your baby sister,” practise independent play, introduce whoever will look after them, and walk through their routine once the baby comes home.

Is it normal for an older child to regress or have tantrums after a new baby?

Yes. Parents report sleep disruption, clinginess, separation anxiety and bigger tantrums, often alongside real affection for the baby. These are usually temporary phases.

How can I help my older child bond with the baby?

Give them small, real jobs, like fetching a nappy, and shared activities such as reading together. A personalised sibling book is one easy way to make the baby part of their story.

What gift should I give my older child when the baby is born?

A gift “from the new baby” at homecoming is a popular tradition. Personalised gifts that celebrate your older child’s own interests show them they are still special and unique.
