My little sister, you are growing into a beautiful young woman. I remember when you were an adorable baby. It feels like yesterday.
On this 13th birthday, may you start turn your passion into a success and may all of your dreams come true, sis!
Beautiful girl, you have made us so happy these past 13 years. We love you and we are going to stand by you at every step along the way!

Seeing you turn 13 makes me the happiest father in the world. Keep shining, keep rocking!
My son, I can’t wait to see you reach more milestones in your life. For now, though, happy b-day!
Thirteen years have flown by so quickly since your mother gave birth to you. Times flies by so quickly, though you should enjoy every moment.
These past 13 years have passed by in the blink of an eye. You have morphed from baby to near-man, and I am so proud of you.

Happy Birthday. Keep shining, keep rocking!

Years ago, you were a little kid and now you are a wise-mouthed 13 year old! Happy birthday!

When you were a baby, I loved you because you were my beautiful, cute baby. Now I still love you very much, for the person you are becoming. Happy 13th birthday!
Blood is thicker than anything else on this earth, and it is my pleasure to be present with you on your 13th birthday.
My son, I will always love you and it makes me so freakin’ happy to celebrate your special day with you!

You have grown so big and strong over these past 13 years. Keep it up!
I can’t believe that it is your 13th birthday, my little brother! It seemed liked it was yesterday that Mom and Dad brought you home for the first time.
The love between brothers is something that nothing else can match. I want to say that nothing makes me happier than to see you on your 13th birthday.
There is no place that I’d rather be than here, celebrating your birthday with you.
These have been an awesome 13 years with you, buddy! Keep it up!
It feels like yesterday that you were annoying me, little brother! Well, honestly, you still do! I love you to pieces, though!
We are very proud to see you celebrate your 13th birthday! May the next years of your life be both creative and truly fascinating.
