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


I’m still not totally convinced that we’re
cousins... I’m sure we are actually sisters
and there was just a mix-up at birth!

Happy birthday, sis!
Happy birthday to you, my dearest cousin!

Another year older and wiser, or I suppose
just older in your case!

Don’t worry, though! You still have many
years to come where you can learn from
me and gain some of my wisdom!
Happy birthday to a cousin who doesn’t
get older, she simply gets more fabulous!

According to my calculations, by the time
you’re an old woman you’re going to be
truly spectacular!

I’m sending you all my love and big kisses
on your special day today!
Sometimes I wish you were my sister
But then I worry we might fight
So to have you as a cousin
Seems to be just right!

Happy birthday to you!
Happy birthday! Your birthday is always a
pleasing time for me as it reminds me that
you’ll always be older than me, cousin!
We must be related because you have so
much style and sophistication just like me!

If people didn’t know any better or that
we’re cousins, they would definitely think
that we’re sisters!

Happy birthday, my dear! I hope you enjoy
your special day today!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
Happy birthday to my 
fondest family member!

A cousin to me you are
But you will always be 
More of a sister, by far!
There are few things in life as special as family, and you’re doubly blessed to have someone as spectacular as me in yours! Happy birthday, cuz!
Happy birthday to one of my dearest relatives! You might only be my cousin but to me, you will always be much more like an annoying younger sister!
Happy birthday to my beautiful cousin, who will always be more like a sister to me!
Growing up together we were inseparable,
and even now years later it is no different!

We are closer than cousins, we are soul
sisters for sure! I hope that you have the
most incredible birthday today that you
deserve, my dear!

You mean so much to me and I just want
to see you happy in life!

A very happy birthday to you, sweetie!
Happy birthday, cousin!

You might not know this, but I’ve always
seen you as more of a younger sister
than a cousin.

It doesn’t even have anything to do with
age, it's simply the fact that you’re just
as annoying as a little sister!
Wishing my sister at heart the
happiest birthday possible today!

Love you, my dearest cousin!
Happy birthday to my favorite cousin!

Very few cousins are made like you
Who mean as much as sisters do!
