Sibling Gender Reveal: Ideas for a Big Brother or Sister
A second (or third) baby means a new big brother or sister. Let them be the star of the reveal.
In this guide · 4
Older siblings often feel the change before the baby even arrives. Giving them the job of revealing the gender makes them part of it, and their reaction is usually the best bit of the video.
Ideas by age
| Age | Reveal idea |
|---|---|
| 1–3 | Let them open a box of pink or blue balloons, or pull a ribbon. Film from their eye level. |
| 3–6 | A T-shirt that says "Big sister" or "Big brother" under a zipped jacket, unzipped on cue. |
| 6–10 | Give them the sealed envelope (if they can keep a secret!) and let them run the countdown. |
| 10+ | Let them plan it: the quiz questions, the music, the time. Teens love being in charge. |
Including siblings in an online reveal
If grandparents and cousins are far away, a live online reveal lets the whole family play together. On Diaper Reveal, each player uses their own phone, so an older child can play on theirs, while a little one can team up with a grown-up on one phone. The winner reveals the gender live to everyone at once, and a memory video is made automatically afterwards. You can even add a quiz question about the big sibling, like "What will they teach the baby first?"
Helping them with the news
- Tell them about the baby before the reveal, so the reveal is about boy or girl, not the baby itself.
- Let them guess and don't make a fuss if they were hoping for the other one. Mixed feelings are normal.
- Give them a job for after the birth too: picking an outfit or a toy.

Frequently asked questions
How can a sibling do the gender reveal?
Give them the moment: a box of balloons to open for toddlers, a "big sister" or "big brother" T-shirt to show for young children, or the countdown and the envelope for older kids.
Can kids play an online gender reveal?
Yes. On Diaper Reveal each player uses their own phone; older children can play on theirs, and a young child can team up with an adult on one phone.
What if the sibling wanted the other gender?
That's normal. Acknowledge the feeling, and give them a special job as the big brother or sister.
