Finding out whether you’re expecting a girl or a boy is a moment many families want to share. That’s where the gender reveal comes in: a get-together where the news comes out in front of the people closest to you. It’s become more and more popular in Lima and across Peru, sometimes as its own party, sometimes as part of the baby shower. Here’s what it is, ideas for the big moment, how to keep the secret until the end and, most important of all, how to do it with no fire, no smoke and no explosives.
What is a gender reveal?
It’s a gathering, big or small, where the parents announce whether their baby is a girl or a boy. There are two ways to go about it: the parents already know and share it with their guests, or nobody knows and everyone finds out together, at the same moment.
The idea took off in 2008, when an American blogger, Jenna Karvunidis, wrote about celebrating the news with a cake that had pink filling. Years later, she said she saw it differently and suggested other ways to celebrate, like revealing the baby’s name instead (TODAY).
It’s worth remembering that the focus is the baby, not the color. A few ways to make everyone feel welcome:
- It doesn’t have to be pink or blue. Pick any pair of colors you like.
- Skip slogans about what a girl or a boy is supposed to like. Teams can be “strawberry” and “blueberry,” or “moon” and “star.”
- If you’d rather not do one, that’s fine too: a name reveal or simply celebrating the baby’s arrival is just as lovely.
How to keep the result a secret
If the parents want to find out along with their guests, the trick is to have someone else receive the result:
- Ask not to be told. Check with your provider whether they can write the result down and seal it in an envelope.
- Choose one trusted person (your mom, your sister, your best friend) to take the envelope and handle the cake, the balloons or the box.
- Let them deal with the vendors. The bakery or balloon shop gets the answer directly and knows it’s a secret.
- Keep it off group chats. Nobody types the result anywhere or snaps a photo of the envelope.
- Have a backup envelope kept by someone else, in case anything goes wrong on the day.
Gender reveal ideas
A cake with colored filling
The classic. It looks neutral on the outside and the color shows up when you cut it. Ask for a bold filling so it pops in photos.
A box of balloons
A big box full of helium balloons that float up when it’s opened. Tie them to something heavy so they don’t drift away, and they’ll double as decorations for the rest of the party.
A giant confetti balloon
A big balloon you can’t see through, filled with confetti in the color. The parents pop it with a pin. Go for paper confetti, which is easy to sweep up.
A surprise piñata
A favorite at Peruvian parties: a neutral piñata stuffed with candy and streamers in the color. The parents take the last swing and everyone sees what falls out.
Confetti poppers
Some confetti launchers work with a spring or with air. Before you buy, check the package to make sure they’re not pyrotechnic and contain no gunpowder.
Scratch-off cards
Every guest gets a card and everyone scratches at the count of three. It works great if some of the family is joining over a video call.
Big brother or big sister
If the baby has older siblings, they can open the box or put on a T-shirt in the color. It’s often the best photo of the day.
Games before the reveal
A few games keep the suspense going while you wait:
- “Girl or boy?” vote. Each guest wears a sticker or ribbon for the team they pick, and the tally is announced right before the reveal.
- Old wives’ tales. The shape of the bump or the cravings are just folklore, but they get people talking: each guest places a bet on their favorite.
- Predictions. Cards to guess the birth date, weight and who the baby will look like.
You’ll find plenty more in our baby shower games guide.
A gender reveal and baby shower in one
Combining the two saves a date and gets everyone together just once. An order that works: arrivals and the vote, food and games, the reveal at the high point of the afternoon, and gifts at the end.
If you don’t know yet whether it’s a girl or a boy when the invitations go out, build the registry with things any baby will use: a stroller, a crib, diapers in several sizes, a bathtub. Our guide on what to ask for at a baby shower lays it all out, and if you already know it’s a boy, our baby boy shower ideas cover themes and decorations; if it’s a girl, the same ground is covered in baby girl shower ideas.
When half the family lives far away, the reveal reads well over video: the one-hour run of show for a virtual baby shower works just as well for both celebrations at once.
Safety: no fireworks, smoke or fire
This part isn’t up for debate. Some gender reveals have ended in wildfires and deaths:
- Arizona, April 2017. At a gender reveal, someone shot a target that contained an explosive substance. The fire burned about 47,000 acres and took around 800 firefighters to contain (NBC News, citing the U.S. Forest Service).
- Iowa, October 2019. A family built a homemade device with gunpowder that exploded like a pipe bomb; a piece of metal killed a 56-year-old woman (Iowa Department of Public Safety).
- California, September 2020. Cal Fire said the El Dorado Fire was caused by a smoke-generating pyrotechnic device used at a gender reveal (CBS News). It burned nearly 23,000 acres, and a firefighter died fighting it (ABC7).
In Peru, SUCAMEC, the agency that oversees explosives and fireworks for civilian use, reminds the public that all pyrotechnics contain substances that produce heat, noise, flashes or colored smoke, that children and teens should never handle them, and that they should only be bought at authorized fairs (December 11, 2025 notice, in Spanish).
For your celebration, leave out:
- Sparklers, fireworks and firecrackers.
- Colored smoke in any form.
- Homemade devices with gunpowder, or anything you have to light or shoot.
- Sky lanterns and anything else with a flame that floats up.
The cake, the balloons, paper confetti and a piñata deliver the same excitement without putting anyone at risk.

Gender reveal questions
Who do you invite to a gender reveal?
There’s no required list. It works best with the inner circle, the people who would want to hear first, because the moment itself lasts seconds and it’s better among people who hug. If you’re combining it with the baby shower, the guest list is the shower’s and you don’t need a separate one. And if you’d rather tell only parents and grandparents, and everyone else by video, that’s still a gender reveal.
How long should it last?
Not long. The reveal itself takes seconds; what stretches is the wait, and that’s where guests get bored or someone lets the secret slip. Decide the time of the big moment in advance, announce it as people arrive (“we’re popping the balloon at five”) and fill the wait with food and a game. On its own, a short afternoon is plenty; inside a baby shower, it’s one more item on the schedule.
Who films the moment?
Someone with one job: filming. Assign it to two people before you start — one shooting horizontally from the front without moving, one taking stills from the side so you get the guests’ faces — and ask them not to join the screaming. Ask everyone else to lower their phones on the count of three: if everyone films, the video is all screens. Check which way the light falls first.
Do guests have to bring a gift?
No. A gender reveal isn’t a shower: what’s being celebrated is news, not the layette. If you don’t want gifts, say so on the invitation in one line (“just bring yourselves”) and repeat it if anyone asks. If you are combining it with the shower, then yes, include the registry link, and leave the gift opening for after the reveal.
Invitation and registry with parati
With parati for baby showers you create the invitation and the gift registry on the same link and share it on WhatsApp. Your guests RSVP and give gifts from their phone, by card or Yape, without creating an account. Big gifts like the stroller can be split into parts so several guests can share them, and El Sueño (The Dream) pools contributions toward something bigger, like the nursery, with a minimum contribution you set. You also see who confirmed and who gave what, so you can thank everyone after the big reveal.
