100+ Birthday Wishes for Your Cousin Sister To Make Her Special Day Sweeter


My dearest relation, who isn’t only an incredible cousin but also an amazing friend and sister to me.

I wish you happiness today on your birthday, and forever more!
Families are filled with many magnificent wonders, but there are few things as wonderful as being blessed with a truly precious cousin.

You must feel pretty lucky to have that in me!

Happy birthday to you today, my dear!
It is true that on paper you are my
cousin, but in my heart, you are
more like a sister to me.

I have so much love and admiration
for you, my dear, and I hope you
know that I will always be here for
you whenever you need me!

I’m wishing you the very best birthday
possible today and I wish you but
happiness for all the days to come!
Happy birthday, my dear cousin!

There aren’t many people I would choose to be my cousin and there are even fewer I’d choose to be my sister. Luckily, I didn’t have to choose between either with you as I was handed the 2 in 1!
Happy birthday, my dear cousin! Congratulations on still maintaining your youthful looks despite the many, many, many years that are against you!
Happy birthday to a unique
Cousin who’s as funny as you
I’m thankful for the laughs
And your true friendship, too!
Happy birthday to you, my dearest cousin!

Another year older and wiser, or I suppose
just older in your case!

Don’t worry, though! You still have many
years to come where you can learn from
me and gain some of my wisdom!
Sometimes I wish you were my sister
But then I worry we might fight
So to have you as a cousin
Seems to be just right!

Happy birthday to you!
Happy birthday to the best cousin ever!

I want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
Laughing at each other or laughing
together, you’ll always be the person
I’ll most enjoy sharing life’s funniest
moments with!

Happy birthday, my sweet cousin!
The only reason that you’re my cousin
and not my sister is because God knew
that the world wouldn’t be able to cope
with us as siblings!

Still, you’ll always be a true sister to
me at heart!

I hope you have the most magnificent
birthday today!
Happy birthday to someone who has taken on two very special roles in my life!

You are my cousin, but first and foremost you are a sister to me!

You are a sister in every sense of the word; you are supportive, caring, and above all someone I can confide in!

Wishing you the best day possible filled with happiness, sis!
Happy birthday to one of my dearest relatives! You might only be my cousin but to me, you will always be much more like an annoying younger sister!
I’m still not totally convinced that we’re
cousins... I’m sure we are actually sisters
and there was just a mix-up at birth!

Happy birthday, sis!
