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


Happy birthday, my dear cousin!

We have so many funny and precious
childhood memories that I realized it
would be impossible for me to pick
just one as my favorite!
A cheeky cousin and a true sister
Wishing a happy birthday to a sister-
like friend and person like no other:
my dearest cousin!

Have a fabulous day, my lovely!
Happy birthday to my partner in crime!
Or should I say, my fabulous sidekick!

You always have and always will be the
absolute best person to have by my side.

I hope you have the most wonderful
birthday ever today, my dear cousin!
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!
It’s no wonder people mistake us for
siblings rather than cousins because I too
sometimes forget that you are my cousin
as you’re so much more like a sister to me!

Happy birthday, my dear! I hope your
special day is as special as you are to me!
Happy birthday, my dear!

I’m wishing you much greatness and joy on your special day this year, as a sweet cousin like you truly is the most beautiful blessing!

I’m so grateful even to have you as a family member and the only thing that could be better is if you were my sister, just like you already are in my heart. 
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!
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!
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!
Don’t worry about getting older, my
dear cousin!

It happens to us all but luckily for us,
we have great genes that should see
us age more gracefully than others!
How fortunate are we!

I hope you have a birthday that’s as
beautiful and fabulous as you are!
