From Only Child to Big Sibling: Helping Your Toddler Adjust

So, you’ve done the big announcement—another tiny human is on the way. Exciting, emotional, and maybe slightly terrifying. But while you’re busy navigating swollen ankles, snack cravings, and Google-searching “is it normal to cry at a TV advert,” there’s another little person who needs some TLC: your soon-to-be big brother or sister.

Toddlers don’t exactly love change (we’ve all witnessed the meltdown when their toast was cut into squares instead of triangles). So, how do we help them adjust when their whole world is about to be flipped upside down by a wriggly, milk-guzzling baby? Here’s my mum’s guide, with a sprinkle of humour and a healthy dose of realness.

While You’re Pregnant

1. Talk About the Baby… But Keep It Simple

Toddlers don’t need a lecture in biology. They just need to know: “Mummy has a baby in her tummy. Soon, you’ll be a big brother/sister.” Use picture books, bump rubs, or even let them talk to your belly (prepare yourself for conversations like “Baby, do you like Peter Rabbit?”).

Our son, Jack, is a bright boy and very inquisitive, and as the baby and my bump have grown he’s asked some great and hilarious questions.

2. Involve Them in the Fun Bits

Let your toddler “help” pick a toy, fold a baby grow, or stick stars on the nursery wall. Do they have any real say in whether the baby gets the rocket-themed sleepsuit? No. But do they feel important? Absolutely.

Jack has been hands-on with things like washing the baby’s clothes and putting them away. We’ve talked a lot with him about baby names and chatted about why “Sonic” and “Spiderman” aren’t really our cup of tea for baby names.

3. Show Them Their New Role

Frame it as an upgrade: “You’re going to be the big one! You get to teach the baby how to play, how to dance, how to eat spaghetti without throwing it at the wall” (well… maybe).

When Baby Actually Arrives

1. Meet & Greet Done Right

When your toddler first meets their sibling, make sure your hands are free. No one wants to feel swapped for a bundle of muslin. Let the toddler get the first cuddle, and maybe have the baby “bring” a gift for their big bro or sis. (Bribery? Nah, we call it bonding.)

2. Make Time for Just-Us Moments

Newborns take up a LOT of attention (read: every waking second). But carving out even ten minutes a day for your toddler—just you and them—makes a world of difference. Reading their favourite story, a walk around the block, or even a snack date at the kitchen table. It says: You still matter.

3. Involve Them in Baby Care (Without Turning Them Into a Mini Nanny)

Ask them to fetch nappies, sing a song during tummy time, or “read” the baby a bedtime story. They’ll feel proud and included—and hopefully less likely to poke the baby in the eye out of boredom.

4. Expect Big Feelings (and Tiny Tantrums)

Regression is real. Potty-trained toddlers may suddenly decide nappies are back in fashion. Sleep routines may crumble. Tantrums might go from “daily” to “hourly.” It’s normal—they’re adjusting. Be patient, keep calm, and know that this too shall pass (eventually).

Final Mum-to-Mum Pep Talk

Helping your toddler adjust isn’t about a perfect Pinterest plan. It’s about small, consistent reassurances that they’re still your baby, even as they step into the “big sibling” shoes.

So:

• Keep things light.

• Celebrate the little wins.

• Laugh through the chaos.

Because while the early days might be messy, noisy, and occasionally fuelled by biscuits, you’re laying the foundation for the most beautiful sibling bond.

And honestly? Watching your first baby become a proud big brother or sister will be one of the most heart-warming moments of motherhood.
