New sibling: how to prepare your child for the new family phase.

A new baby is a celebration for parents, but for the older sibling it can mean something quite different: the feeling that the world is about to change, and not necessarily for the better from their point of view. It doesn't mean they won't love the baby — it just means the transition needs some preparation and a lot of patience.

First, understand

Why this phase is hard, even with preparation.

However excited your child seems during the pregnancy, mixed feelings usually show up once the baby is actually home — jealousy, regressions (asking for diapers, a bottle or constant holding again) and even irritation at the extra attention the newborn gets. That is expected and it is not a sign of rejecting the sibling: it's the normal process of adapting to a big change in the family.

🤰 Before the baby arrives

Laying the groundwork early.

1
Share the news simply, at the right time
There is no single "right" age, but for young children telling them closer to the birth (the last 2–3 months) usually works better: time is still an abstract concept, and a long wait creates more anxiety than needed.
2
Involve your child in the preparations
Let them pick a toy or an outfit for the baby, help set up the room or choose a decoration. Feeling part of the process, instead of just a bystander, builds an early connection with the sibling.
3
Read books about a new sibling
Picture books help children process feelings through a character before living the situation — and they naturally open up conversations about it.
4
Make routine changes ahead of time
If your child is moving rooms, potty training or starting daycare, make those changes at least a few weeks earlier — so they don't associate everything with the baby's arrival at once.
5
Be honest about what changes (and what doesn't)
Avoid promising that "nothing will change". It's more honest and more reassuring to say: "the baby will need a lot of holding at first, but I'll still play with you and I love you just the same".

👶 When the baby arrives

Hospital and the first days.

6
Plan the first meeting calmly
If possible, keep the parents' hands free when your child comes to meet the baby (baby in the crib, not in your arms) — so the first hug belongs to the older sibling, with nothing to compete with.
7
Have a gift "from the baby"
A small present your child receives "from their sibling" on the first visit helps link the baby's arrival to something positive, not only to changes.
8
Protect one-on-one time, even if short
In those busy first days, a few minutes of full, undistracted attention (no phone, no baby in your arms) go a long way for your child to feel their place is still safe.

🗓️ The weeks and months after

Supporting the adjustment day to day.

9
Expect and accept regressions, without punishing
Asking for a bottle again, having accidents after being potty trained, or wanting to be held more often are common ways of processing change. Punishing or shaming tends to stretch the phase; calm acceptance resolves it faster.
10
Include them in caregiving, without forcing
Simple, optional tasks — bringing a diaper, singing to the baby, picking the outfit of the day — help your child feel part of the team. Never force it, but always invite.
11
Name the jealousy without judgement
"Sometimes it's hard to share mum's attention, right? That's normal" helps far more than "you don't need to be jealous". Validating the feeling reduces the need to prove it through tantrums or aggression.
12
Keep the rituals that already existed
Holding on to the older child's routines (the bedtime story, a specific outing, the same Saturday snack) signals that their place in the family is still guaranteed.

✅ Quick checklist by phase

Save it for later.

Before the birth → share the news, involve them in preparations, read books about it
At the hospital → plan the first meeting, have a gift "from the baby"
First weeks → protect one-on-one time, accept regressions without punishing
Following months → include them in care, name the jealousy, keep old rituals

🚩 Signs to watch

When extra support helps.

Recurring physical aggression aimed at the baby, even after conversations and supervision
Very intense regressions that persist for many months with no sign of improvement
Persistent sadness, withdrawal, or changes in appetite and sleep in the older child

In these cases, talking to your pediatrician can help you decide whether closer follow-up is worthwhile.
