Celebrating an 18th birthday is a momentous occasion. You took that jumping bean in your belly and raised it through its blob phase. You survived life as the mother of a toddler. You even got through the tweens. And now you have a legal adult standing before you. Of course, we know that parenting doesn’t stop at 18 years old. They’ll still have their hearts broken, end up in big fights with best friends, and always need their family to fall back on. Millennials can tell you firsthand that while 18 might make you legally an adult, there’s a good chance you’ll be relying on your parents for years to come. Depending on your outlook, this could be a good or bad thing, huh? Worry about them moving into your basement when they turn 30 in… 12 years. For now, focus on the present: Your baby is 18 years old! And you’re going to need some clever 18th birthday captions to commemorate this milestone on social media.

Of course, what you write on an 18th birthday post for your kid can depend on how you plan to celebrate this big birthday. Will you buy them their first official scratch-off ticket? Are you letting them take that long road trip with their friends now? For many “kids,” they’d just be happier to have the curfew bumped out by an hour. However you celebrate, you’ll no doubt find yourself ready to mark the occasion with a proud post on social media. Every amazing or embarrassing picture deserves a funny or heartfelt caption tagged to it. For that, the following 18th birthday picture captions have you covered.
