100 It’s a Girl & It’s a Boy Captions for Instagram to Share Your Happy News

Sharing pregnancy or birth news is personal. If you decide to announce that you are expecting a girl or boy on Instagram, choose a caption that sounds like you and shares only the details you are comfortable making public. You can keep it short, add a little humor, or write a longer note for family and friends.

This collection has 100 baby girl and boy announcement caption ideas grouped by mood. Edit names, dates, and details before posting; a caption should reflect your own news rather than imply that everyone has the same experience.

How to Write a Baby Announcement Caption

Share only the news your family is ready to make public. An announcement can name the baby's arrival or expected arrival, but you do not owe readers a due date, location, health detail, or explanation of how you learned the baby's sex. If your photo includes an ultrasound, check what personal information is visible before posting.

Choose a line that matches the timing. “We are expecting” fits a pregnancy announcement; “our baby is here” belongs after birth. If a color, cake, or prop is in the picture, you can mention it, but the caption does not need to follow a pink-or-blue theme. The examples below are creative suggestions, not a script for every family. Change or skip any detail that is not yours to share.
