1) Wear the News

A popular means of announcing a little girl’s soon-to-be promotion to big sister is with “Big Sis” and “Big Sister, Finally!” shirts and dresses.

Do a google search to find one you like, or if you don’t mind putting a bit of time and effort into it, make your own.

After you have the shirt, have your little girl wear the shirt next to your newborn baby. Then, add the photo to a custom photo birth announcement and share your great news with friends and family.

2) Signs & Banners

Snap a photo of your little girl holding a DIY sign inscribed with her special news.

You can keep things simple with chalk and a chalkboard or pen and paper or go the more fancy route and purchase a pre-designed baby announcement sign online.

Pumpkins, sand, a sidewalk, and even snow can also be used to write a message on. Here are a few cute messages you can inscribe your sign with:

“I’m being promoted to big sister.”

“Pink or blue? Mommy’s due with number two!”

“I’m so sweet that my parents decided to make another one!”

3) Embrace the season

Incorporating hints of the season into your sibling birth announcements can add a lot of color and fun to your special news.

If your baby arrived in fall, try writing your special news on a pumpkin. Have your little girl hold the pumpkin while standing next to your new baby.

For an easier option, embrace summer by taking a photo of your newborn and daughter in a fresh field of flowers, in a park, or at the beach.

4) Sisterly Love

Snap of a photo of your little girl and your new baby together. If your little girl is old enough, you can even take a photo of her holding the baby.

If not, simply snap a photo of your little girl kissing your new baby or take a photo of her hugging her new sibling.

5) Baskets & Baby Carriages

Since your baby will likely still be a newborn when you’re taking your big sister announcement or birth announcement photos, it will be good to have a safe and comfortable place for them to rest while taking the photos.

Baskets and carriages will not only provide your newborn with comfort and safety, but also add character and charm to your photos.
