124+ Birthday Wishes for Your Younger Sister That Will Touch Her Heart

The fact that you’re turning another year older simply makes me feel older than ever! Thanks a lot, little sis!

Happy birthday, little sis! You keep trying to catch up with me but you never will! I’ll always win when it comes to being older than you!

We may have bickered, you
may have made me lose my
temper, but you must know
that I love you more than
anything, baby sis!

Have a wonderful birthday!

Happy birthday to you!

How is it that each year you get older, yet you become more and more beautiful, little sis!

Well, I’ll tell you why… It’s because you’re related to me! It runs in the family, my super gorgeous sister!

Happy birthday, baby sister!

Like the finest wine you just keep improving with age, sis! Just like your elder sister, then! 

Happy birthday to my baby sister who sometimes is so annoying that I wish she was far away, but deep down I know I would miss her after just one day!

Happy birthday from your elder brother!

No matter how much you
grow or how old you become,
you will always be my baby sis!

May your birthday be filled
with joy!

You were such a bratty little sister, always trying to take my things and tag along everywhere I went. Things had to be done your way or you would throw a tantrum.

Despite this, I want you to know that I love you to bits.

Have a fantastic birthday!

Happy birthday to a crazy girl I’m blessed to call my sister! You’re the life of the party and the star of the show, little sis!

Is this day just special? No, it's the most special day of all. It is the birthday of my baby sis. Your birthday is even more special than my own. For this was the day I gained my best friend and companion for life.

Have an awesome birthday!

You can’t stop getting older, little sis,
so your only hope is that you grow old
gracefully like me! Happy birthday to you!

Many years ago you were born and I must confess it wasn’t love at first sight. I was used to being the centre of attention, but that all changed very quickly. It was like I went to bed one-night being number one and woke up the following morning in second place. There was a new baby in the family.

I may not have been the best sibling during your first days of life and I may even have wished that you had never been born. But I quickly learnt that my worries were unjustified, for I was still number one. Maybe not to everyone anymore, but that no longer mattered. There was now a new little someone who adored me… you.

I want you to know, little sis, that I adore you too. Have the greatest of birthdays.

Little sister, you’re getting older each
year but that doesn’t necessarily mean
you’re growing up!

I hope you always stay the funny and
cheeky little girl I know and love, and
who growing up with was a total blast!

Happy birthday to you today!

Remember the days when I used to pick you up from school and we would just talk and talk all the way home. I would help you with your homework just so I would have more time to be with you. Then, later at night, I would read you a story.

I love spending time with you and being able to confide in you! I love you, little sis!

Have a fabulous birthday!

Happy birthday, sister!

Enjoy your youthful beauty while you
still can, little sis, because once you
get to my age that all starts to change!
