29 First Birthday Instagram Caption Ideas For Baby

Your child won't remember their first birthday when they get older, but when they look back at the pictures you took, they'll see how beloved they were. There are so many moments you'll want to capture in photographs that first year, and turning one is perhaps the biggest moment of all. If you're planning to share those photos for your friends and family members to be a part of the festivities from afar, these sweet Instagram captions for first birthdays will help convey the magic of the day.

Whether you're celebrating with a Kardashian-level bash or keeping it simple with a smash cake and some family and friends, you're obviously going to need to take tons of cute photos to remember everything. You only turn 1 once, after all, and you and your child will both want to look back on the special memories someday. My oldest child is almost 4 by now, but I still love flipping through pics from her 1st birthday bash, and seeing how much she's grown and changed since then (and what an awesome job I did planning that party, to be honest).

These 29 cute captions are perfect for a special baby's big day, whether you want something funny, something sentimental, or something perfect for that epic cake smash.
