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!
Sometimes crazy but always amazing
Happy birthday, my dear cousin! Congratulations on still maintaining your youthful looks despite the many, many, many years that are against you!
Happy birthday, girl!

I count my blessings each and every day
for having a cousin like you. You truly
are a very special person in my life.
You are so very special to me, my dear cousin, and it’s no secret that I have always been very protective of you as I have always seen you as more of a little sister rather than a cousin.

When we were kids I’d only want the best for you, and I knew then that you too would always have my back.

It’s such a joy to see that now you’re getting older, you are developing into this incredible and beautiful person!

Happy birthday, my dear, and I hope that today brings you all the happiness in the world, which you so very deserve!
My darling cousin, congratulations on yet another incredible year!

I’m a strong believer that blood is thicker than water, and particularly in our case, it couldn’t be any more accurate! Our bond is so close, more likened to that of sisters, and I wouldn’t change that for the world.

Have a truly wonderful birthday, my dear! You deserve it more than anyone!
Happy birthday to my dear cousin!

I’m so grateful to have had you in my
life since we were kids! 

You are everything I could ever wish
for in a cousin and more. In truth, I
have always seen you as more of a
sister figure in my life than a cousin.

I hope that you know you can always
rely on me, the same way I know I
can rely on you!

Have a fantastic birthday, sis!
A cousin on paper
A sister at heart
I could never cope
If we were ever apart!

Wishing you the happiest
Birthday possible, my dear!
Happy birthday to my cousin who, as it so happens, has the best cousin in the world!

If ever there was a more suitable time to thank your lucky stars, it would be now! You are truly blessed to have a wonderful friend and sibling in me!
Sure, getting lots of gifts on your birthday
is nice but no gift will ever be as great as
simply having a wonderful cousin like me!

Happy birthday, girl!
Wishing a happy birthday to a sister-
like friend and person like no other:
my dearest cousin!

Have a fabulous day, my lovely!
Take a really deep breath, cousin, because you’re going to need all the air in your lungs to blow out so many candles today!

Happy birthday to you, my dear!
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!
Happy birthday to my dear cousin!

We were inseparable as kids,
spending almost every minute
together! I honestly don’t know
what I would’ve done without
you growing up!

In truth, we’ve always been so close
and we were together so much
throughout our childhood that I have
always seen you more like a sister
to me than a cousin.

Wishing you all the love and happiness
in the world on your special day!
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!
