Preparing Your Child for a New Sibling

Bringing a new baby home is a big adjustment for the whole family, and that includes your older child/children. One of the questions I get asked most often in antenatal appointments is how to prepare an older sibling for the change ahead.

There's no single right way to do it, every child and every family is different, but there are some gentle, practical steps that tend to make the transition easier for everyone.

When to Tell Your Child

There's no fixed rule here, it depends on your child's age and how they process time. Younger children, especially under threes, often don't have a strong sense of "months away", so waiting until you're visibly pregnant or closer to the birth can make more sense.

Older children who ask questions or notice changes may benefit from knowing earlier, so they don't feel like something is being kept from them.

Whenever you choose to share it, keep the first conversation simple and calm. Something like "we're going to have a new baby join our family" is enough. You can build on the detail over time as their questions come up.

Involving Them During Pregnancy

Children tend to adjust better when they feel part of what's happening rather than something happening to them. A few ways to involve them:

Let them be present at an antenatal appointment if it feels right, hearing the heartbeat or seeing a scan photo can make the baby feel real to them. I always welcome siblings being around during appointments, it's a lovely way to include them from the start
Talk about what babies are actually like, that they cry, sleep a lot, and can't play straight away, so expectations are realistic
Involve them in small preparations, choosing a soft toy for the baby, helping set up the nursery, or picking out a going home outfit
Read books together about becoming a big brother or sister, there are lots of gentle, age-appropriate ones available
Talk positively about their new role, "big sister" or "big brother", without putting pressure on them to be grown up overnight

Preparing for the Birth Itself

Think through practically who will care for your child while you're in labour or giving birth, whether that's at home or in hospital, and make sure that person is someone your child feels safe and comfortable with. Familiarity matters here more than almost anything else.

If you're planning a home birth, it's worth talking through in advance what that will look like for your older child, whether they'll stay at home during labour, go to a relative's house, or something in between. Every family does this differently, and there's no wrong answer, just whatever keeps things calmest for your child.

Keep their normal routine as steady as possible around the birth itself, even small consistencies like the same bedtime story or the same breakfast can be reassuring when everything else feels different.

The First Meeting

The first meeting between siblings can be a lovely, memorable moment, and a few small things can help it go smoothly:

Try to have your arms free when your child comes in, so you can give them a proper hug first, before introducing the baby
Consider having a small gift "from the baby" for your older child, it's a lovely gesture and helps them feel included rather than replaced
Let them approach the baby in their own time and their own way, some children want to hold the baby straight away, others hang back, both are completely normal
Praise gentle, caring behaviour when you see it, it reinforces the role they're stepping into

Managing Jealousy and Regression

It's very common for older children to show some jealousy, clinginess, or even regression (things like wanting a bottle again, or asking for nappies) in the weeks after a new baby arrives. This isn't a sign anything has gone wrong, it's a completely normal response to a big change in their world.

A few things that tend to help:

Try to carve out some one to one time with your older child, even ten or fifteen minutes of undivided attention can make a real difference
Involve them in baby care in small, age-appropriate ways, passing a nappy, choosing an outfit, singing to the baby, so they feel like a helper rather than a bystander
Acknowledge their feelings without judgement, "it's hard sharing mummy and daddy sometimes" goes a long way
Keep your expectations realistic, this adjustment period usually settles over weeks, not days

One of the best tips I can give is to keep your child's normal routine going once the baby arrives. If they go to nursery, a childminder, or school, keep those days running as usual rather than pausing them. Routine is grounding for little people, and having that steady, familiar rhythm in the middle of a lot of change helps them feel safe and settled.
