A second or third bub means a new big bro or big sis. Here's how to make them the star, and how to get the grandparents in Perth or Manchester watching too.

Older kids often feel the change before the baby arrives. A real part in the reveal makes the news theirs too, and their reaction is usually the best bit of the video. The trick is matching the job to what they can actually do without stress.
Sibling reveal ideas by age
| Age | Their job | Idea |
|---|---|---|
| 1 to 3 | Open or pull | Open a box of pink or blue balloons or pull a ribbon. Film at their eye level and keep it under a minute; toddlers lose interest fast. |
| 3 to 5 (Kindy, Prep) | Guess and show | Let them pick pink or blue as their guess first, then unzip a hoodie or open a bag with a "Big sister" or "Big brother" top inside. |
| 5 to 10 (Prep to Year 5) | Run the moment | They hold the sealed envelope, run the countdown and press the button. A grown-up stands beside them and knows the answer. |
| 10 to 13 (upper primary, Year 7) | Co-host | Let them help send the link, pick a game or two and read out the guesses. Tell them the result early only if they can keep a secret. |
| 14+ | Plan it | A teen can set up the party, film it and edit a short clip. Ask, don't assume; some would rather just watch. |
Who knows the answer?
Usually just one adult. After the morphology scan (the mid-pregnancy scan, often around 18 to 22 weeks) ask the sonographer to write the result down and seal it, so a chatty child doesn't hear it in the room. Read when you find out the baby's gender in Australia for the timing. Little kids rarely keep secrets, so it's fine for them to find out at the reveal like everyone else.
Five steps for an online reveal with the big kid in the middle
- Pick the time. Weekend mornings and early evenings suit kids best. If grandparents are overseas, work out the hour for each city first; our guide for Aussie families overseas shows how.
- Create the party on Diaper Reveal. It's free and you don't need an account or card to start.
- Send the link in the family WhatsApp group. Guests join in their phone's browser with the link or a six-letter code, with no app and no sign-up.
- Give the big kid the job. They hold the phone or the sealed envelope and press go while everyone plays on their own phone. The result shows on every screen at once.
- Save the clip. Ask someone to film the child's face. Relatives who slept through it can watch afterwards.
If the big kid isn't thrilled
It's common for a child to hope for the other one and look sad for a moment. Don't comment on the reaction in front of everyone. Give them a minute, have a cuddle, then talk about what's fun about being a big brother or sister. It usually passes quickly. A small gift from the baby, like a toy they pick out at Kmart or Big W, can help the day end well.
Keep the party easy on kids
- Keep the live part short; 15 to 20 minutes is plenty for under-fives.
- Skip anything that burns or smokes in summer. Check your state's fire bans if you're planning an outdoor reveal.
- Have one helper next to the youngest kids so the parents can enjoy it.
- Add a family guess round so the siblings aren't the only ones guessing.

Frequently asked questions
How do I include my older child in the gender reveal?
Give them one job that suits their age: toddlers open a box or pull a ribbon, Kindy and Prep kids guess and unzip a "Big sister" or "Big brother" top, primary-school kids hold the sealed envelope and run the countdown, and teens can help plan it.
Should the big brother or sister know the result beforehand?
Usually not, especially little kids who find secrets hard. Let one adult know the answer. Kids from about 10 can be told if they are helping and can keep it quiet.
What if my child is upset about the baby's gender?
Don't make a fuss about the reaction in front of everyone. Give them a moment, offer a cuddle, then talk about what will be fun about being a big brother or sister. Hoping for the other one is common and usually passes fast.
Can we do an online gender reveal with the kids and family overseas?
Yes. Send a link in WhatsApp, pick a time that works across time zones and put a helper next to the youngest kids. Everyone plays on their own phone and the result shows for everyone at once.
Do guests need to download an app?
No. On Diaper Reveal guests join in their phone's browser with a link or a six-letter code, with no app and no sign-up.
