Happy Birthday 18-Year-Old Granddaughter
- To my dear granddaughter on your 18th birthday, may you always be healthy and full of energy. Believe it or not, I remember the day you were born like yesterday. You are still my baby even if you are all grown up. I enjoy hearing about your daily adventures and had so many laughs watching you grow into the fine young woman you are today. Happiness and good health like you deserve my dear.
- Happy Birthday to my very special Granddaughter, who just turned eighteen. Everything about you is beautiful, as you have been blessed with a pretty face and a nice body. I hope you grow to be an inspiration to many and a pillar of strength. Wishing all your wishes come true on this special day!
- Happy Birthday. I hope that you always stay the graceful, kind-hearted, and beautiful person that you are. From your loving grandmother!
- You were my little princess when you were five. I watched in amusement as your tiny little hands took care of everyone. As others grew taller than you, I consoled you and said that height doesn’t determine the age. Today you are eighteen, a grown-up woman no longer a child. The innocence of your childhood is lost forever, but your spirit remains young! Happy birthday!
- It’s hard to believe I was so small when you were giving me advice from the time I could understand. That seems like yesterday! Now you’ve grown into a beautiful young lady. I remember how shy you used to be. But now you stand tall, strong, and confident. Grandpa and Grandma are proud of you, we love you very much.
- Happy Birthday to the most precious person in my life! I hope this special day is filled with fun, excitement, and happiness. You have been such a blessing in my life, I’m so glad that you are mine! Make this special day even more unforgettable by always being yourself. You’re the best!
- 18 is a big deal in terms of your age. I am happy you have finally lived this long to make you proud. Today, God has given me another reason to celebrate. He allowed you to live this day and continue giving him praise. As your Nana, it is my responsibility to buy you an armload of presents. You did not let me down the other times and I will not do so today too.
- You were still a baby when I first held you in my arms. I was knocked over by the beauty and pureness that radiated off you; as if an angel had put her light on you. Even at this moment, I can still feel the wonder of how precious life is, and how truly blessed I am to be a part of it. Happy Birthday!
- You are 18 years old today – a grown-up teenager! How time flies. I remember when you were only six years old and I used to carry you on my back when we went to parks. You were so adorable. I am very happy for you. Congratulations on your big birthday!
- Dear granddaughter, my most beloved 18-year-old! It’s your lucky day! 8.74 billion seconds in the lives of 7 billion people is equal to one second in your life. How great it feels to have someone so special like you in my life! Happy Birthday!
