How to Prepare the Firstborn for the Arrival of a New Baby
By Dr. Roberto Albani, Pediatrician and Gastroenterologist
Guiding your firstborn through the transition to older sibling
The arrival of a new baby always brings a whirlwind of emotions. For parents, it’s a moment of joy and anticipation, but also a time filled with questions and uncertainty about how the family dynamic will change. For the firstborn, however, it represents a profound shift: from being an “only child” to becoming an “older sibling.” This transition requires time, sensitivity, and a steady parental presence.
Love doesn’t divide — it grows. Preparing your firstborn for a new sibling
How does the first child experience the wait?
For a young child, the idea of a sibling’s arrival is often abstract. “In mommy’s belly” may spark curiosity, but it’s not something they can truly grasp. Until the baby is actually born, the firstborn can’t imagine what it means to share attention, time, and space that previously belonged only to them.
You can’t expect them to understand everything right away; instead of overexplaining, it’s more effective to help them gradually experience the change.
Involve them in small preparations
Invite them to help with simple tasks: choosing a stuffed toy for the baby, organizing a drawer together, or looking at pictures of when they were a newborn. These moments help them feel included—not as spectators of an adult-only process, but as active participants in a new beginning.
Actions matter more than words
This is a delicate phase in which words matter, but gestures matter even more. Children perceive far more from tone of voice, facial expressions, and attention than from explanations alone.
If the pregnancy is lived with calmness and tenderness, they will feel it. If instead they sense worry, nervousness, or stress, they may associate those emotions with the baby and perceive the arrival as something threatening.
Often, very little is needed: keeping the routine as unchanged as possible, setting aside exclusive moments just for them, and reassuring them that—even when the baby arrives—they will still have their parents’ full love and a space that’s theirs alone.
Avoid talking too much about the future
A common mistake is overloading the child with talk about the baby or upcoming changes. Especially for young children, the future is difficult to grasp; they live fully in the present. A long, expectation-filled wait can create confusion or even anxiety.
It’s better to stay concrete and simple:
“When the baby is here, you can show him your toys.”
“We’ll read stories to him together—or while he’s sleeping.”
Such everyday examples help the child imagine what’s coming without feeling overwhelmed.
Don’t ignore uncomfortable reactions
It’s completely normal for the firstborn to swing between enthusiasm and irritation. Sometimes they want to be close to their mother; other times, they withdraw. They might ask endless questions and then suddenly stop asking anything at all.
These behaviors are not early signs of jealousy—they’re signs of adaptation. The child is trying to understand what will change for them.
Instead of correcting them or offering excessive reassurance (“Don’t worry, you’ll be so happy!”), it’s far more helpful to welcome and name their emotions:
“I understand that sometimes it feels strange that another baby is coming… It’s new for us, too. I know it might feel scary to think someone could take your place—but that won’t happen.”
When parents show understanding, the child feels seen, heard, and not judged.
Reassurance is essential
One of the strongest needs during this stage is knowing that—with the baby’s arrival—their place remains secure.
The routine may change, but the bond with the parents does not.
Saying and showing that love doesn’t divide—it multiplies is simple, but fundamental.
Even small everyday gestures—a private moment of play, a morning cuddle, a short phrase that makes them feel important—build a sense of continuity and safety.
So, dear parents…
don’t worry too much. The arrival of a new baby is not just a birth, but an opportunity for a family rebirth.
Everyone’s role changes, everyone adapts—and so does the firstborn.
And when parents manage to experience this wait as a shared journey, as an added value made of presence, listening, and time, the baby on the way will be welcomed not only by Mum and Dad… but also by a heart already prepared to love them.
