Happy birthday to my best friend
and sister at heart, who just so
happens to also be my cousin! 

Have a great day, girl!
My cousin, spirit guide and sister at heart
Cousin, you'll always be more like a sister to me
Happy birthday, my dear!

We might have been born into our family
as cousins, but the truth is that really we
are much more like sisters!

I hope that your special day brings you as
much happiness as you have brought to
me over the many years!

You deserve nothing but the best life has
to offer, my dear!

Big kisses!
We have a close bond, cousin
My heart says we are sisters
I’m sending the very best birthday wishes your way today, my adorable little cousin sister! May your special day be a beautiful one full of love, joy, and happiness!
A cousin who still isn't showing her age
Sometimes crazy but always amazing
A family member like you isn’t just a beautiful addition, but a true blessing.

I feel so lucky to have you as my cousin, and even luckier that I’m able to call you my best friend and sis. Your presence in my life is heart-touching, as you truly mean the world to me.

Happy birthday to you today, my dear.
Having a cousin like you growing up meant that I had the best childhood possible.

To me, I’ll always see you not only as my cousin but also as a best friend and sister.

Happy birthday to you, and thank you for all the happy memories, my dear.
A cheeky cousin and a true sister
You're just like a sister to me, cousin
For someone who is a cousin, a dear
friend, and also a sister to me, I thought I
had better get you not one gift, but three!

May you have the absolute best and
happiest birthday possible today!
You’re my favorite girl alive, cousin
A cousin sister who is utterly cool
My dear, I am wishing
you the very best on
your special day today!

Deep down in my heart
you are my sister, even if
officially you are my cousin.

You are such a beautiful soul
and I wish for nothing but the
best in life for you, as you truly
deserve it.

I hope you have the most fab
birthday ever!
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!


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!
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!
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!
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 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!
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, 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.
