We always told you to be careful and you never listened. I’m looking forward to many more years of ignored advice.
Happy birthday, dearest daughter. Surprising though it might seem, you are and always have been a gift from heaven.
Every day I thank God for you. Now that my little girl is turning 18, it’s hard to know where the years went, but I know that the best is yet to come.
Our affection for you grows day by day. Enjoy your 18th birthday, sweetheart!
You were adorable as a child, and you are beautiful as a woman. But the best part is who you are on the inside.
Even though you may have fewer chances to play dress up, I hope you’ll never stop playing.
Though part of me is sad to see you grow up, I’m also excited to see the woman that you’ve become. We are proud of you.
I want you to know how much I appreciate you as my friend and that I respect your honesty and simplicity. I wish you a very happy birthday!
The world changed when you came into it. As you grow up, I hope you continue to make it a better and happier place.
The more you give, the more you get. Remember that I’ve given you a lot over the years.
You are sweet, beautiful, and kind. On your birthday, I hope you stay well.
I like so many things about you, they won’t all fit in this card. Just know that I wish you a very happy birthday!
You caused so much mischief as a child, I’m scared to see what you’re going to do as an adult.
Happy birthday to one of the coolest people I know!
Happy 18th birthday to one of my dearest friends! Today is surely a day to celebrate!
Happy birthday! Best wishes for your 18th!
Now you’re an adult. Please grow up, but never grow old. Please.
The choices you make today determine where you’re going to be tomorrow. Make good ones!
Now is the time to decide what kind of person you are going to be, which is much more important than deciding on your career. Choose wisely!
I hope you wake up tomorrow and realize how lucky you are to have had me as a friend for so many years. But that’s tomorrow. Today is about you.
You’ll soon find out that being an adult is much less exciting than being a child. But shhhh, don’t tell anyone. That’s our secret.
Welcome to the club of adulthood. However, we’d prefer it if you didn’t let the police know because otherwise we’ll soon meet you behind bars.
On your first day of adulthood, I hope you enjoy the day and night as much as possible. And make sure you leave the tab for someone else.
Another year older, and you just keep getting more amazing! I can’t wait to see what this year brings for you.
Now that the most carefree days of your life are behind you, get ready for the burden of adult life.
Welcome to the adulthood club, where we only have one rule: No rules! Happy 18th birthday, dear!
Great! Now I can arrest you legally ;)
We’ve known you were wonderful for each of the past 18 years. Hope you have a great party tonight!
Welcome to manhood. It’s time to leave childish things behind (even video games). Happy 18th!
On your 18th birthday, we wish you a fantastic party and an even better year!
Now that you’re 18, you need to be careful about the mischief you cause or else. . . we can sue you!
Now that you’re 18, you need to be careful—your parents can legally throw you out! Happy 18th!
The day you understood that everyone is imperfect, you became a teenager. The day you forgive them is the day you will be an adult.
Thank you for all the joy you’ve brought us through the years. You have a special heart.
Since it’s your 18th birthday, I’m wishing 18 times for your continued success!
Happy, happy birthday for a dear, dear friend!
Today, let’s not say 18 years old and instead say 18 years young.
Your age only matters to the police and insurance companies. To people who love you, you will always be ageless.
These are special years now, where you are neither very, very young nor very, very old. But for you, I hope that they are very, very happy.
My only goal today is to make sure you have nothing to worry about. Save your worrying for tomorrow.
I hope you’ll keep an open heart and open spirit as you gain life experience.
You can grow older but please please please please please please please never get old.
Just like your nose and ears, my love for you will only grow with the years.
Keep this up and soon you’re going to be 100 years old.
Um. I think you’re awesome. Happy birthday!
Personally, I couldn’t care less if you were 18 or 80. It all means the same thing to me: time to party!
Welcome to adulthood! I wish you a great 18th birthday and hope each and every dream comes true.
Your sweet childhood is no more. It’s time to lament the end of your innocence. Still, Happy 18th!
The little girl I knew so well is now a woman! Happy 18th birthday, dear!
You’re no longer a kid so it’s time to start watching where you step. Welcome to the always-fun grown-up world!
Even though you’ve turned 18 and are technically an adult, don’t be fooled. You are still a kid and will be for the next 18 years!
We all know for a fact that you are still just an 8-year-old with ten years of experience. I hope you have a great birthday!
Now that you’re 18, I’m going to start coming to you for advice. And money.
You’re never too old to play games or dream big. I pray you keep a smile on your face and a youthful spirit.
Life is a journey, and you’ve only just begun.
Life is what you make of it! Happy 18th!
I am so happy to have you in my life. The best is yet to come.
Put away your worries for the day. Adulthood can start tomorrow, but today we need to celebrate!
You might think you’re old because you’ve turned 18, and that’s only because you still don’t know anything.
You’ve already brought us so much joy. I can’t wait to see what you do with your next 18 years.
No matter what the future brings, I’ll always be there for you. You’re never too old to need a helping hand (sometimes two).
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).
Welcome to adulthood! It’s all downhill from here :)
Throw an awesome party and have some fun! Happy 18th birthday.
May your future be forever bright. To us, you will always be a source of light. Happy 18th birthday!
Congratulations on this special day. The coming years of your life are sure to be exciting!
Enjoy the moment, the day, and your teenage years for as long as possible. Wishing you a memorable 18th birthday!
Today my heart and soul will only sing one song for you: “Happy Birthday!”
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.
Turning 18 is a great life experience. Don’t miss the excitement!
You’re an adult now, but don’t let it go to your head. Seriously, the younger you think, the younger you’ll stay.
You’re not a kid anymore. Happy birthday and welcome to manhood!
Now that you’re 18, you’re responsible for covering for your own mistakes. Unfortunately, those don’t stop at any age.
You’re 18! How does it feel to finally be responsible for your actions?
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 now old enough to legally buy tobacco, but as far as I’m concerned, you were already smokin’.
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.
