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


When two cousins are as close and as inseparable as we are, you might as well just call them siblings!

Happy birthday, my dear!
Laughing at each other or laughing
together, you’ll always be the person
I’ll most enjoy sharing life’s funniest
moments with!

Happy birthday, my sweet 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! Your birthday is always a
pleasing time for me as it reminds me that
you’ll always be older than me, cousin!
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!
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!
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!
Wishing my sister at heart the
happiest birthday possible today!

Love you, my dearest cousin!
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!
You are more than a cousin to me, you’re more like a sister. Mainly because you dedicated your childhood to irritating me!

Happy birthday, cuz!
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!
My dearest cousin, you are
the sister I was never lucky
enough to have and I wish
you only beautiful things
on your very special day!

Happy birthday!
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!
Wow, another birthday already, cousin?
With all these years behind you now,
perhaps you’ll finally start to grow up soon!

I’m just kidding with you! I wouldn’t change
your fun and playful personality for the
world! Happy birthday to you!
