Telling an older child is a different moment from telling the grown-ups. Here is how to do it in simple words, and five ways to give them a real part in the online reveal.

Short answer: tell your older child first or at the same time as the family, in a calm moment, with short words and one clear message: a baby is coming and they are still your child too. Give them a job in the reveal, such as holding the card, pressing the button or making the guess, and let them join the online party on their own phone or yours.
Before you tell them
- Choose the moment. Pick a rested, unhurried time, not bedtime and not in the middle of a busy party.
- Tell them yourself. Children often repeat news quickly, so ask relatives to wait until you have talked to your child.
- Keep it short. One or two sentences are enough. Let them ask questions and answer only what they asked.
- Mention what stays the same. Their bedtime story, their special time with you and their routines are not going away.
Simple words by age
- Toddlers (about 2-3): "There is a baby growing in my tummy. You are going to be a big sister." Use a picture book or point to their own baby photos.
- Preschool (about 4-5): add what they will see: "The baby will be small and need lots of help. You can help me choose a blanket." Questions will keep coming, so repeat the answers calmly.
- School age (6 and up): share the due date, let them mark it on a calendar, and ask what they would like to do with the baby. They may like to help pick the name list.
Five online reveal ideas where the big sibling has a role
- The button job. The child presses "reveal" on the countdown. Practise once so the moment is smooth.
- Guess first. Let your child make a guess before the grown-ups. Everyone cheers whichever answer comes, so nobody feels wrong.
- Big sibling quiz question. Add a question such as "What will the big sister teach the baby first?" and let the child answer.
- Announcer. The child reads the result from a card or says the name of the baby you chose, with a parent beside them.
- Wish for the baby. After the reveal, the child types or says a short wish. Grandparents abroad love hearing it live.
Doing it online with family far away
Relatives in another country can watch the moment their grandchild learns the news. Create a free party, send one link or a 6-letter code, and everyone joins from a phone, tablet or laptop with no app and no account. The party is available in 24 languages, so grandparents can use their own. Put the start time in each person's time zone, and let the little one sit on a parent's lap with one shared phone if they are too young to hold their own. More party ideas for children are in our kid-friendly gender reveal guide, and gender reveal with siblings covers the reveal itself.
A simple 20-minute order
- Tell your child privately, before the party.
- Open the party and welcome everyone in one sentence.
- Let the child make a guess, then collect the guests' guesses.
- Count down together and let the child press reveal.
- Hear the child's wish and the family's wishes.
- Finish with a photo or short video of the new big brother or sister.
Family will often ask what to bring or send once they know. A free baby registry that works with any shop lets you share one list, and you can add a few small gifts for the big sibling too.
Frequently asked questions
When should I tell my older child about the new baby?
There is no single right time. Many parents tell their child before or at the same time as the wider family, so the child does not hear it from someone else. Choose a calm moment and keep the message short.
How can a young child take part in an online gender reveal?
Give them one small job: make a guess, press the reveal button, read a card or add a wish for the baby. A toddler can join on a parent's phone.
What if my child wanted the other gender?
Say it is fine to feel that way and focus on what they can do with the baby. Letting them guess first helps, because every answer is celebrated.
Do relatives need an app to join the online reveal?
No. With Diaper Reveal guests open a link or type a 6-letter code on their phone, tablet or laptop. There is no app and no account, and the party is available in 24 languages.
How long should the reveal with kids be?
Keep it short, around 20 minutes, because children lose focus quickly. Do the reveal early in the call and leave wishes and photos for the end.
