Preparing Your Child to Become a Big Brother or Sister
Welcoming a new baby is a huge change for the whole family — including the little person who is about to become a big brother or sister.
They may be excited, curious, confused, proud, worried or completely uninterested. Sometimes they might feel all of those things in the space of an afternoon!
There is no perfect way to prepare a child for a new sibling, but there are lots of gentle ways to involve them, reassure them and help them understand what life with a new baby might actually look like.
1. Talk About the Baby in an Age-Appropriate Way
Young children don't necessarily understand pregnancy, due dates or how long nine months lasts.
Keep conversations simple and appropriate for their age.
You might talk about how the baby is growing, let them feel the baby move or look at scan photographs together.
For younger children, linking the baby's arrival to something they understand — such as “after Christmas” or “when the weather gets warmer” — may be easier than giving them a date.
And don't feel you need to talk about the baby constantly. Let your child guide some of the conversation too.
2. Expect Lots of Different Feelings
We often expect children to be delighted about becoming a big brother or sister.
Some are.
Others aren't particularly impressed!
Your child may feel excited one day and worried the next. They might ask endless questions or seem completely uninterested.
As the baby's arrival gets closer, they may also become more clingy or seek extra reassurance.
Try to give them opportunities to talk about how they're feeling without suggesting that there's a "right" way to feel.
3. Involve Them in Some of the Preparations
Giving your child small choices can help them feel included.
Depending on their age, they might enjoy:
- Choosing between two baby outfits
- Helping put baby clothes into drawers
- Choosing a teddy or comforter for the baby
- Looking at baby names together
- Helping prepare the nursery
- Choosing a book to read to their new sibling
Keep it light-hearted rather than making helping with the baby feel like a responsibility.
They're becoming a sibling — not an extra parent.
4. Look at Their Own Baby Photographs
This is such a simple way to help children understand what's coming.
Show them photographs from when they were newborns.
Tell them about how tiny they were, what they liked and the funny little things they used to do.
You could show them their first sleepsuit, favourite blanket or baby book if you've kept them.
It can help them understand that they were once the tiny baby everyone was preparing for too.
5. Explain What Newborn Babies Are Actually Like
Young children can sometimes imagine that their new sibling will arrive ready to play.
The reality of a newborn who sleeps, cries, feeds and isn't particularly interested in their carefully selected toys can therefore be slightly disappointing!
Gently explain that newborn babies are very small and need lots of help.
Tell them that the baby won't be able to play straight away but will gradually learn to smile, sit, crawl and interact with them.
6. Prepare Them for What Will Happen When the Baby Arrives
If you'll be going into hospital or a birth centre, explain what will happen to your child while you're away.
Who will look after them?
Where will they sleep?
Who will take them to nursery or school?
When might they see you?
Knowing what their own routine may look like can make the change feel less mysterious.
Keep explanations simple and avoid making promises about exactly when you'll return, as birth doesn't always follow a timetable.
7. Make the First Meeting Gentle
That first sibling meeting can feel enormously significant to adults.
Your child may react differently.
They might immediately want to cuddle the baby.
They might glance at them and ask for a snack.
Both are absolutely fine.
Allow the relationship to begin naturally rather than expecting a picture-perfect first meeting.
If they want to hold their new sibling, help them do so safely with close adult supervision.
8. Keep Some Familiar Routines
Life inevitably changes when a newborn arrives, but maintaining some familiar parts of your older child's routine can provide reassurance.
Perhaps Daddy still reads the same bedtime story.
Perhaps Saturday morning still means pancakes.
Perhaps they continue attending their usual clubs or seeing grandparents.
Small pieces of normality can feel particularly comforting when everything else suddenly seems different.
9. Make Space for One-to-One Time
A newborn naturally demands a lot of attention.
Finding occasional moments when your older child has you to themselves can help remind them that their relationship with you hasn't disappeared.
It doesn't need to be an elaborate day out.
Ten minutes reading together, doing a puzzle, having a cuddle or chatting at bedtime can still feel special.
When friends and family visit the new baby, it can also be lovely when they remember to say hello to the older sibling rather than heading straight for the newborn.
10. Don't Be Surprised by a Little Regression
Some children temporarily return to behaviours they'd previously grown out of after a new baby arrives.
They might want more help getting dressed, ask to be carried, have changes in sleep or become more emotional.
A new sibling is a big adjustment.
Offer reassurance and patience while keeping appropriate boundaries and routines.
If you're concerned about significant or persistent changes in your child's behaviour, speak to your health visitor, GP or another appropriate healthcare professional.
11. Let Their Relationship Develop Naturally
You don't need to manufacture a perfect sibling bond.
Your older child might enjoy fetching a muslin, choosing the baby's clothes or singing them a song.
Or they might prefer to carry on building Lego while you feed the baby.
Both are fine.
Give them opportunities to interact without forcing affection or involvement.
Their relationship has years to grow.
12. Celebrate Their New Role — Without Forgetting Who They Already Are
Becoming a big brother or sister is exciting, but it shouldn't suddenly become your child's entire identity.
Celebrate their new role while continuing to notice everything else that makes them them.
Their interests.
Their achievements.
Their friendships.
Their wonderfully silly jokes.
They're gaining a sibling, but they're still your little person too.
A New Chapter for the Whole Family
Bringing home a new baby changes family life.
There may be beautiful first cuddles and proud introductions — alongside jealousy, tears, interrupted bedtimes and moments when your older child would quite happily send the baby back!
That's okay.
Sibling relationships aren't created in one magical first meeting. They grow through thousands of ordinary moments over the months and years that follow.
Give your child time to adjust, keep offering reassurance and let their relationship with their new sibling develop at its own pace.
One day, you may look across the room and realise that somewhere amongst all those ordinary moments, something rather lovely has begun.
