For your oldest child, a new baby is a big change. The good news: how you share the news can make them feel proud rather than pushed aside. Give them a role, a title and, ideally, their own shirt, and "a baby is coming" becomes "I'm going to be a big brother."
This guide covers simple ways to tell a toddler, announcement photo ideas that star the big sibling, and shirts made for the moment.
Telling your toddler: keep it simple and positive
- Use short, concrete words. "There is a baby growing in Mommy's tummy. You are going to be a big sister." Toddlers do not need the details.
- Tie the timing to something they know. "The baby comes when it is warm again" means more to a three-year-old than a due date.
- Give them a job. Picking a stuffed animal for the baby or helping choose a going-home outfit makes them part of the team.
- Read a book about becoming a big sibling together. It gives them words for their feelings.
- Expect mixed feelings. Excitement, questions and a little jealousy are all normal. Extra one-on-one time helps.
Make it official with a big sibling shirt
A shirt gives the announcement a clear moment: they put it on, everyone cheers, and they get to wear their new title to daycare, the grocery store and Grandma's house.

Sibling announcement photo ideas
- The reveal video: hand them a wrapped box with the shirt inside and film their reaction.
- The "promotion" photo: sit them in a big chair with a sign reading "Promoted to Big Brother."
- Shoes in a row: their sneakers next to a tiny pair of baby shoes.
- The sonogram hold: let them hold the ultrasound picture while wearing the shirt.
- The chalk wall: write the due month in chalk and let them "sign" it with a scribble.
Frequently asked questions
When should we tell our toddler?
Many families wait until the pregnancy is announced to friends and family, since toddlers are not great at keeping secrets. Tell them before they hear it from someone else.
Can I add their name to a sibling shirt?
The matching sibling sets above let you add a name. Each product page shows exactly which details you can add.
What if my child is not excited?
That is normal. Keep it low-pressure, give them a special job and plenty of attention, and let the shirt be a fun extra rather than a big moment they have to perform.
