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


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!
A cheeky cousin and a true sister
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!
Happy birthday to my cousin who, as it so happens, has the best cousin in the world!

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!

be much more like a sister!

Enjoy your special day, my dear!
Lots of love, big kisses and
enormous hugs to you!
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!
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!
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!
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!
