Here are some of our favorite ideas to share your joy in thoughtful, funny, and memorable ways. Best of all, most of these ideas make for excellent keepsakes so you can look back fondly on this special time.

1. Big Brother Superhero T-shirt

Create a baby announcement with your son wearing his favorite superhero T-shirt and the words “Big Brother.” Whether your child loves Batman, Superman, Aquaman, or another character, this makes for a fun announcement about his new sibling.

2. Not an Only Child Anymore

This fun pregnancy announcement idea is all about celebrating your child getting a little brother or sister. Make a sign that says “I’m not an only child anymore. A little one is on the way!” Then add the little guy or gal’s due date so loved ones know when the bundle of joy is scheduled to make an appearance.

3. Leveling Up to Big Brother

If you’re a gamer, consider an announcement card that features a picture of your child playing a video game. Add the words, “Leveling up to big brother” to share the news with loved ones. 

4. Big Bro Shirt

Give your child a kid’s T-shirt that says “big bro” in bold font. Have them strike a pose or take an action shot to serve as your pregnancy announcement photo. You could also have your son jump and then add a phrase on his big brother T-shirt like, “Jared is jumping for joy because he’s about to be a big bro!”

5. Filling In Some New Shoes

For this adorable big brother announcement, all you need is a picture of your little boy’s shoes next to a pair of baby shoes. You can add a phrase like, “Caleb is about to step into a new role as a big brother” or “Miguel has some new shoes to fill as big brother” for a sweet way to share the news.

6. Baby Number Announcement

If the new baby is about to gain more than one sibling, a baby number announcement is a great way to share the news. Have your children wear T-shirts with the number that represents their birth order. Then make a sign that says “Baby number 3 [or whichever number is appropriate] is on the way!”

You can hire a professional photographer to take photos or simply snap some pics on your phone. Have your children hold the sign together for a cute announcement, then upload the photo to your digital card before sending it off to family and friends. 

7. Digging It Announcement

Another fun way to announce your child’s promotion to big brother is to get a shirt with a digger machine on it. Add text that says “I’m digging my promotion to big brother” or “Can you dig it? I’m going to be a big brother!” for a festive statement.

8. Fine Print Onesie

Order a onesie bodysuit that says something like “Always read the fine print” in large letters. Below that text, put an asterisk and use a smaller font to write the words “big brother” Take a picture of the older sibling holding the onesie and upload it to your birth announcement card. 

9. I Have a Secret Chalkboard

Share your exciting news by taking a photo of a chalkboard with the words “I have a secret” written on it. Add flowers in pink or blue if you want to also announce the gender or keep it neutral with flowers and balloons in various hues. Share the image on your sibling pregnancy announcement card and include a quick note about a soon-to-arrive baby shower invite.

10. Family Shirt Announcement

Get the whole family in on the fun with a photo shoot where everyone gets to wear a special tee announcing your baby’s arrival. The kids can wear sibling shirts with different messages. For instance, one could say “I’m finally getting a little sister [or little brother],” while another one might declare “I have a new sidekick arriving soon,” or “I’m going to be a big brother again!” 

11. Share the News With Disney Attire

If your family loves Disney, get them in on the fun with a movie-themed announcement. You can dress up the family as Disney characters and add a tagline that says “Another character is joining the bunch!”
