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


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!
Officially you’re my cousin, but my heart
says you’re my sister. Luckily for you, I
always listen to my heart!

Happy birthday to you, my dear. I
hope you have a truly wonderful time
celebrating your special day today!
Age might not be your friend, cousin, but I always will be! You can always rely on me for sisterly support no matter how old you get!
Happy birthday, my dear cousin! Congratulations on still maintaining your youthful looks despite the many, many, many years that are against you!
If you weren’t my cousin
You would be my sibling
As you truly are my sister 
Just from another mister!

Happy birthday, my dear!
My sweet cousin, you’re as dear 
and meaningful to me as any sister
and just as annoying as one, too!

May you have a fabulous birthday!
Wishing a very happy birthday to my
favourite cousin today!

You’re like a little sister to me, and you
always remind me of myself when I was
your age! It’s wonderful to see that you
are such a happy kid, living an enjoyable
childhood just like I did!

I wish you many more happy years and
that your smile never fades! Sending
you lots of love and big hugs on your
special day, sweetie!
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!
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 my beautiful cousin, who will always be more like a sister to me!
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!
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!
Happy birthday to a cousin who doesn’t
get older, she simply gets more fabulous!

According to my calculations, by the time
you’re an old woman you’re going to be
truly spectacular!

I’m sending you all my love and big kisses
on your special day today!
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!
