Adorable Sibling Pregnancy Announcement Ideas

Updated
Make your pregnancy announcement extra special by involving your older child with these creative sibling announcement ideas.
Announcing a new addition to the family is a massive milestone. It gets even better when you include a soon-to-be big brother or sister in the reveal.

Involving your older child in the pregnancy announcement helps them feel important rather than replaced. Plus, their reactions usually make for the cutest photos.

We pulled together this list to spark your creativity. Here are 50 fun, heartwarming, and hilarious ideas for sibling pregnancy announcements that the whole family will love.


Key Takeaways

  • Involve them early: Giving siblings a job, like holding a sign or wearing a special shirt, helps them feel ownership over the new baby news.
  • Match the personality: Choose an announcement style that fits your child, whether they are funny, serious, or totally oblivious.
  • Use props: Simple items like balloons, shoes, or letter boards make the message clear and photo-ready.
  • Capture the candid: Sometimes the best announcements come from genuine, unposed reactions to the news.

50 Pregnancy Announcements With a Future Big Sibling

There are countless ways to share the news, but getting the siblings involved is our favorite. Here are the best ideas to help you decide how to tell the world your family is growing.

1. Promotion From Only Child

Nothing beats the classic job promotion notice. Grab a chalkboard or a letter board, write out the new “Big Sister” or “Big Brother” title, and let your little one show off their impending status upgrade. It is simple, effective, and adorable.

2. Here We Go Again

If this isn’t your child’s first rodeo, lean into the humor. These shirts are perfect for experienced siblings who know exactly what’s coming. They are usually made of soft cotton blends, making them comfortable enough for a quick photoshoot or for wearing to school to break the news to teachers and friends.

3. Planning For Fun

Let your child decide what kind of buddy their sibling acts as. Whether it is a “Partner in Crime” or “Player 2,” giving them a choice helps them bond with the baby before they even arrive.

4. Hugging Both

If your toddler is too young to hold a sign or sit still, just go for a hug. Capture a sweet moment of you embracing your child while holding a strip of ultrasound images. It is subtle, sweet, and clearly communicates the news.

5. More Trouble For Mom And Dad

Lean into the chaos. If your current child is a ball of energy, use a sign that jokes about “adding more trouble” to the house. It is a funny, honest way to let friends know you are ready for the madness of two.

6. Seasonal Siblings

Tie your news to the calendar. Using holiday-themed props or shirts makes the timeline clear to everyone. This specific idea focuses on Easter, but you can find similar designs for Halloween, Thanksgiving, or Christmas. Check the sizing charts carefully on these seasonal items to ensure a good fit for photos.

7. The Absent Sibling

Rainbow babies are special, and honoring a sibling who passed away is a beautiful way to include the whole family. This announcement style acknowledges the loss while celebrating the new hope on the way.

8. A Drip Drip Drip Of Information

Keep it minimalist. A simple “Baby #2” sign, some photobooth-style pictures, and your child’s smiling face are all you need. The black and white aesthetic often makes these photos look timeless and classy.

9. We Must Be Quackers

Puns always win on social media. Use a common phrase or figure of speech to bring some levity to the announcement. It shows off your family’s sense of humor and gets the message across instantly.

10. A Simple Smile

You don’t need elaborate props. A “Big Sister” sweatshirt and a giant grin work perfectly. This approach puts the focus entirely on your child’s excitement rather than the props around them.

11. Big Brother Gift Set

Turn the announcement into a game. Dress your son in a cape and mask to announce that a “Super Big Brother” is on duty. This set usually includes a book, which is a great tool for helping him understand his new role long after the photo is taken.

12. Siblings Implied

You don’t always need the kids in the frame. A row of shoes representing each family member, including a tiny pair for the new baby, is a classic pregnancy announcement. It implies the siblings’ presence without the struggle of getting everyone to look at the camera.

13. Pretty Boot Camp

If your older child has a nurturing side, set up a “Big Sibling Boot Camp.” Have them practice diapering a doll or pushing a stroller. Snap a photo of their training session to show the world they are preparing for duty.

14. Chalk And Ice Cream

Bribery works wonders for photos. Give your little one a favorite treat, like ice cream, and write the due date on a chalkboard next to them. You get a happy child and a great photo.

15. Excitement Shines

Capture the pure joy. A professional photoshoot can highlight the genuine excitement on your child’s face. These high-quality images are perfect for printing and framing later.

16. Book It

Education is part of the process. Have your child hold or read a book about becoming a big sibling. It serves as a prop for the announcement and a helpful resource for explaining the changes coming to your household.

17. Hanging Out

Include the pets. A “guard dog” or “big brother” bandana on the family dog, sitting next to your human children, makes for a chaotic but lovable announcement.

18. Sweet Dreams

Naptime is the perfect time for a photo. While your child sleeps, arrange a sign or ultrasound photo next to them. It is an easy way to get a still shot without wrangling a toddler.

19. Wish List

Personalize it to their hobbies. If your son loves trucks, fill a dump truck toy with the ultrasound photo. If your daughter loves painting, have her paint a “Baby” sign. It connects their current interests to their future sibling.

20. Fab Fam

Get the whole squad in matching outfits. It shows unity and makes for a clean, cohesive visual. Plus, you can reuse the outfits for family gatherings later. Just be prepared for plenty of diapers in your near future.

21. Too Cute For Words

Use humor to break the tension. A sign that says “I was too cute to be an only child” explains exactly why you decided to have another one. It is a compliment to your firstborn and an announcement all in one.

22. Nothing Else To Say

Let the shirts do the talking. A simple “Big Brother” or “Big Sister” tee is straightforward and effective. Everyone immediately understands the message without needing to read a long caption.

23. Terrific Trio

If you have multiple kids, give them each a role. Numbered shirts (1, 2, 3) or signs allow everyone to feel included. It visualizes the growing family lineup perfectly.

24. Very Happy New Year

Ring in the year with a surprise. New Year’s Eve is already a celebration, so adding a baby announcement multiplies the excitement. Party hats and confetti make for great props.

25. Trike To Be Filled

Set the stage for a playmate. Show your child on their bike or trike with an empty one parked next to them. It symbolizes the fun they will soon have with their new best friend.

26. Beau-Tee-ful

Coordinating a large family can be tough, but matching tees makes it easier. These sets allow you to buy as many as you need for a consistent look. Look for pre-shrunk cotton options to ensure they fit well after a wash.

27. Bigger Table Needed

Focus on the dinner table. A photo of the family eating with a high chair set up for the new arrival is a subtle, lifestyle-focused announcement. It shows how the dynamic of daily life is about to change.

28. Furry Sibs

Don’t leave the pets out. A sign around your dog’s neck that says “Big Brother” acts as a hilarious sibling announcement, especially if your human children are also in the frame.

29. The Mix

Kitchen themes are classic. Photograph your child wearing a chef’s hat or holding a whisk with a “Bun in the Oven” sign. It puts a fresh, kid-friendly twist on an old cliché.

30. Numbers Game

Do the math for your friends. Use large wooden numbers or balloons to show the birth order (1, 2, 3) and place the final number next to a pair of baby shoes.

31. Signs

Keep it candid at the park. Have the kids play on the swings or slides while mom and dad hold a sign in the foreground. It feels natural and less staged than a studio shoot.

32. Tippy Toes

Focus on the feet. A shot of everyone’s feet, from dad’s large boots down to the toddler’s sneakers and a pair of baby booties, tells the whole story without showing faces.

33. Toy Story

Use the playroom floor. Spell out “Baby” using blocks, cars, or dolls. Have the older sibling lie next to the message. It is colorful, playful, and easy to set up at home.

34. Work It

Incorporate your careers. If dad is a firefighter or mom is a nurse, use uniforms or gear alongside the kids to announce the newest “recruit” to the team.

35. Ready For A Second

Go for the matchy-matchy look. Mom and daughter in identical dresses, holding a onesie for the new baby, makes for a visually striking photo that Instagram loves.

36. Role Prep

Set up a classroom scene. A chalkboard listing the “Big Brother Rules” or “Lessons in Progress” is a clever way to show the older child preparing for their responsibilities.

37. Bad Luck Dad

Self-deprecating humor is always a hit. A sign pointing to dad that says “He lost his man cave” or “There goes the sports car” adds a funny, relatable layer to the news.

38. A Long Time Coming

Acknowledge the wait. If there is a large age gap, use a sign like “Finally!” or “Worth the wait.” It personalizes the announcement and answers the inevitable questions about the age difference.

39. Run Away

Stage a funny exit. A photo of the older child packing a bag or “running away” because they don’t want to share their toys is a humorous take on sibling rivalry.

40. Grumpy Pants

If your child cries during the photoshoot, use it. A crying toddler next to a “I’m not happy about this” sign is real life at its finest. It is funny because every parent knows exactly how that feels.

41. Everyone’s A Winner

The tie-breaker concept. If you have one boy and one girl, announce the third baby as the “Tie Breaker.” It is a fun sports reference that fits perfectly for a third child.

42. Short ‘n Sweet

Sometimes less is more. A letter board that says “Baby Lastname, Due Month/Year” held by the sibling is elegant and gets the job done without fuss.

43. Balloon Signs

Balloons add instant festivity. Use gold or silver letter balloons to spell out “BABY” behind the family. It creates a party atmosphere in the photo instantly.

44. Prego Twist

The pasta sauce joke creates a funny visual. Have the older sibling hold a jar of Prego sauce while mom holds her belly. It is silly, recognizable, and easy to execute at the grocery store or home.

45. Drive It Home

Use vehicle metaphors. A “Sidekick” or “Co-Pilot” sign works great if you frame the photo in or around the family car. It implies that the adventure is about to continue.

46. Waiting For Dinner

The empty chair approach. Place a sign saying “Reserved for my new playmate” on an empty chair at the kids’ table. It is poignant and sweet.

47. Movin’ On Out

Serve an eviction notice. A photo of the youngest child in their crib with an “Eviction Notice” sign (due to the new tenant arriving in 9 months) is a viral favorite for a reason.

48. Onesie Fun

The tug-of-war. Have two siblings pull on a baby onesie as if they are fighting over it. It highlights the impending sharing struggle in a cute way.

49. A Perfect Gift

Wrap it up. For a Christmas pregnancy announcement, put the ultrasound or a pair of booties inside a gift box and let the siblings open it for the camera.

50. All Ages

Write the ages on their feet. Write the year of birth on the soles of everyone’s shoes, including the future year on a pair of baby shoes. It is a creative perspective that emphasizes the timeline of your growing family.
