Welcoming a second baby is an exciting milestone for your growing family! There are tiny clothes to unpack, baby names to discuss and another little person to fall in love with. But amongst all the excitement, there’s someone else whose world is about to change: your first child.

One day, they’re the centre of your attention. The next, there’s a tiny new family member who needs feeding, changing, cuddling and lots of love.

So how do you help your little one adjust to becoming a big brother or sister?

The good news is that with patience, reassurance and a few thoughtful preparations, you can help make this new chapter a positive experience for the whole family.

A Big Change for Little Hearts

As adults, we understand why a new baby needs so much care. But for a young child, sharing Mum and Dad’s attention can feel confusing.

Your little one might be thrilled about becoming a big sibling. They might be curious, uncertain, jealous or completely uninterested.

And sometimes, they might feel all those emotions in one afternoon!

Every child adjusts differently, and there’s no single correct reaction to a new baby.

The important thing is to help your older child feel loved, included and secure throughout the changes ahead.

1. Start Talking About the New Baby Before Birth

You don’t need to wait until your baby arrives to begin preparing your first child.

Explain the pregnancy in simple, age-appropriate language. For younger children, you might say, “There’s a baby growing in Mummy’s tummy. When the baby is ready, they’ll come home and live with us.”

Try reading picture books about becoming a big brother or sister, looking at photographs of your older child as a newborn or talking about what babies need.

Be realistic, too. Explain that newborns cry, sleep and drink milk, and won’t be ready to run around and play straight away.

This helps your little one understand what to expect without creating unrealistic expectations.

2. Let Your Child Be Part of the Excitement

Children often enjoy feeling involved in family preparations.

Depending on their age, invite your little one to choose a baby blanket, help arrange the nursery or pick a special storybook to read when the baby arrives.

You could even let them choose a little outfit for their new sibling.

If they’re interested, tell them about how the baby is growing. You could explore five surprising things babies learn in the womb together.

Just remember that not every child will be excited about baby preparations, and that’s okay too. Keep invitations gentle rather than making participation a requirement.

3. Keep Familiar Routines Where Possible

New babies bring enormous changes to family life.

Suddenly, there’s less sleep, more washing and a whole lot of juggling!

For your older child, familiar routines can provide comfort and reassurance.

Try to maintain regular bedtime stories, mealtimes and favourite activities wherever practical.

If you’re planning a big change, such as moving your toddler from a cot into a bed, try to avoid making it happen at exactly the same time as the new baby’s arrival.

A little familiarity can make a big transition feel less overwhelming.

4. Make the First Meeting Feel Special

The moment your children meet for the first time can be incredibly emotional.

Perhaps your older child will be bursting with excitement. Perhaps they’ll stare at the baby for a few seconds before asking for a snack!

Both reactions are perfectly fine.

When possible, greet your older child warmly and give them your full attention before focusing on introducing the baby.

Let them approach at their own pace.

You could say, “Would you like to come and see your new baby brother or sister?”

If they want to help hold the baby, arrange a safe, seated, fully supported cuddle with close adult supervision.

There’s no need to insist on kisses, hugs or photographs. Your children have plenty of time to get to know one another.

5. Set Aside Special One-on-One Time

One of the loveliest things you can do when welcoming a second baby is remind your first child that they’re still just as important to you.

Even a short period of undivided attention can be meaningful.

Perhaps it’s ten minutes of building blocks, a quick walk around the garden or reading their favourite book together.

If you’re feeding your newborn, invite your older child to sit beside you for a story or a quiet conversation.

And when possible, allow your partner or another trusted family member to spend special time with them too.

Your family is growing, but your first child’s place in your heart isn’t getting any smaller.

6. Expect a Little Jealousy (And a Few Surprises!)

Your previously independent toddler suddenly wants to be carried everywhere.

Your potty-trained preschooler starts having accidents.

Your usually cheerful child becomes clingy or asks whether the baby can go back!

While these changes can be frustrating, temporary regression and jealousy are common responses to a new sibling.

Try to acknowledge your child’s feelings rather than making them feel guilty.

You might say, “It feels hard when Mummy is busy with the baby, doesn’t it? I love spending time with you too.”

Avoid repeatedly telling them they’re a big boy or girl now and shouldn’t act like a baby.

They are still little, after all, and they need reassurance too.

If distress becomes severe, persists or affects daily functioning, speak to your child’s healthcare professional for personalised support.

7. Encourage a Bond Without Forcing It

Not every child falls instantly in love with their new sibling.

Some take weeks or months to become comfortable with the changes.

Encourage small moments of connection.

Let your older child help choose a lullaby, bring you a clean nappy or show the baby a favourite toy while you supervise.

Praise gentle behaviour, but don’t make your older child responsible for caring for the newborn.

Always supervise young children around babies, even when they’re affectionate and eager to help.

As your baby grows, little smiles, giggles and interactions may gradually help the siblings develop their own unique relationship.

Don’t Forget About Yourself, Mum!

Welcoming another baby can be wonderful, exhausting and overwhelming, sometimes all in the same day.

You may wonder whether you’re giving both children enough attention or worry that your firstborn feels left out.

You don’t need to make every moment perfect.

Accept help when it’s offered, make time for rest where possible and remember that your family is learning to adjust together.

The American Academy of Pediatrics offers additional age-by-age guidance on preparing children for a new sibling, including ways to support toddlers, preschoolers and older children.

A New Chapter, A Whole Lot More Love

There’s something truly special about watching your family grow.

One day, your oldest child might be teaching their little sibling how to build a tower, sharing a favourite story or making them laugh until their tiny tummy shakes.

There may be arguments over toys and plenty of chaotic moments along the way, but there will also be countless opportunities for love, laughter and wonderful memories.

You’re not replacing the beautiful little family you already have. You’re adding another precious chapter to its story.
