Having a little sister means you always have someone to play with, fight with and blame things on. 

So, when it comes to their special day, it’s only right that we go out of our way to say “Happy Birthday Sister” and show them how important they are and how dull our lives would be without them in it.

Make them smile with a heartfelt Happy Birthday Little sister quote or make them laugh with a funny sister wish and remind them where they learned it all.

If I were able to choose my family, I would still choose you. Happy Birthday little sister!

Happy birthday to the greatest little sister in the world. I am so lucky to have you and I wouldn’t change you for the world.

To my little sister, we have shared so many moments that no one else will understand. We have laughed at inside jokes, had our own catchphrases, and been there for each other throughout all the difficulties that life has thrown at us. There is no better best friend than you. I am so happy to have you in my life.

Whenever I feel sad, I think of you and soon I have a reason to smile again. Happy birthday little sister.

Little Sister, I wish you all the happiness of this world and many more birthdays to come. Enjoy your day and seize every moment life gives you.
