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

I hope everything you wish for comes true for you today, cousin, but really what more could you want other than a wonderful family member like me!

Happy birthday, girl!

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!

For a cousin and a sister all rolled into one
I’m wishing you a birthday that’s full of fun!

Happy birthday, my dear! 

Here’s to the many years of laughter and 
creating wonderful memories together 
that are still waiting to be written!

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 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!

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!

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!

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!

I wanted to get something extraordinary 
and particularly special for a cousin 
who is more like a sister to me, 
but then I realized something:
You already have all of that in me!

I hope your birthday is as wonderful and 
as meaningful as you are to me, my dear! 
Wishing a very happy birthday to you!

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.

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. 

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!
