Thank you for bringing the best kind of joy, wonder and love into my life — the granddaughter kind. You make me feel brand new. Wishing you the very same on your birthday, sweetie...and every day afterwards!

You're like sugar. You make everything so  delicious. Your birthday reminds me that, if you hadn't come into this world, life would have been flavorless. You make everything so much sweeter. Happy birthday, sweet baby!

You are my little princess, my light, my joy. Happy birthday, sweetie!

You deserve to win the "Best Granddaughter of the Century" Award every year, especially on your birthday! I love you! Happy birthday, my little award winner!

Happy birthday, darling! May every birthday you celebrate take you on another new and fantastic year-long adventure — not just because you deserve it and we love you, but because it will also make every moment of the next 365 days as amazing as you.

Just recalling all the amazing times we've spent together brings me such happiness. Thank you for being a wonderful, wonderful granddaughter. Warm wishes for a wonderful birthday, cutie-pie.
