18th birthday messages

When someone in your life is turning 18, it’s the first milestone birthday they’ll have experienced, aside from their 16th. To think, they can legally drink and paint the town red now, so there’s a lot to consider when you’re putting pen to paper!

Here are some of our favourite happy 18th birthday messages:

  1. Let’s make your 18th birthday one to remember! Old enough to be responsible for your mistakes…which, let’s be honest, don’t stop at any age!
  2. Happy 18th birthday! It’s all downhill from here!
  3. Welcome to adulthood! Time to do all those things you’ve been patiently waiting to do since you were 15… right?
  4. For your 18th birthday, my gift to you is… the freedom to do everything with the money to do nothing!
  5. Happy birthday! You’re now eight, with 10 years’ experience!

Whether it’s your child’s big day, your best friend’s, or your partner’s special birthday, we all know that turning 21 is a big moment in someone’s life. You might be a bit stuck for ideas writing your 21st birthday message to someone because it’s such an iconic birthday. But we’ve got some corkers in mind for you to pinch!

Here are some happy 21st birthday messages to write in their card:

  • Everyone always wishes they could be 21 again, so enjoy making them all jealous for the next 365 days!
  • Only nine years till 30… best get that party started!
  • You’re 21! Now everything is legal. Sadly, legal often ain’t quite as fun!
  • No pressure, but by the age of 21, Steve Jobs had already founded Apple. I’m sure you’ve got something big lined up though, right?
