You’re an adult now, but don’t let it go to your head. Seriously, the younger you think, the younger you’ll stay.

My beloved niece, my friend, happy 18th birthday! Dear, today I want to tell you that, no matter how old you become, always keep alive your inner child in your heart. Celebrate your day in a grand way and enjoy.

My sister, happy 18th birthday! I’m so happy for your entrance into the new stage of life. You know that how much I love and admire you. Keep smiling sis and have a wonderful and adventurous life.

You’ve now become an adult and today I pray to God that, he gives you much maturity that you don’t mess up with your innocent little sister anymore.

My, princess, your 18th birthday has arrived! I’m so happy for you dear. This is a new phase of your life. Dream more to get more. Have a wonderful journey of life.

You’re now old enough to legally buy tobacco, but as far as I’m concerned, you were already smokin’.

You can now vote, get a tattoo and buy a lotto ticket… though I highly recommend doing those things one at a time.

You’re 18! How does it feel to finally be responsible for your actions?

Now that you’re 18, you’re responsible for covering for your own mistakes. Unfortunately, those don’t stop at any age.

You’re not a kid anymore. Happy birthday and welcome to manhood!

Turning 18 is a great life experience. Don’t miss the excitement!

On your 18th birthday, my number one piece of advice is for you to take a deep breath, do some reflecting, and make a cool start.

Today my heart and soul will only sing one song for you: “Happy Birthday!”

Enjoy the moment, the day, and your teenage years for as long as possible. Wishing you a memorable 18th birthday!

Congratulations on this special day. The coming years of your life are sure to be exciting!

May your future be forever bright. To us, you will always be a source of light. Happy 18th birthday!

Throw an awesome party and have some fun! Happy 18th birthday.

Welcome to adulthood! It’s all downhill from here :)

My advice to you on your 18th birthday is: don’t be afraid to make mistakes, to fall in love, or to ask for help. Also, save money (less fun but also very important).
