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


Happy birthday to my witty sister-like cousin!

Spending so much time with me must have rubbed off on you, as you’re funnier than ever now!
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!
Wishing my sister at heart the
happiest birthday possible today!

Love you, my dearest cousin!
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!
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!
The only reason that you’re my cousin
and not my sister is because God knew
that the world wouldn’t be able to cope
with us as siblings!

Still, you’ll always be a true sister to
me at heart!

I hope you have the most magnificent
birthday today!
Happy birthday to my favorite cousin!

Very few cousins are made like you
Who mean as much as sisters do!
Happy birthday to my dearest cousin!

I can still remember all of the long
summers we spent together growing up!
What amazing times we had and they
are memories I will treasure forever!

We were always in each other’s pockets,
never apart from one another. We were
so very close, much more like sisters
than cousins!

You’ll always be special to me, despite
the busier schedules we have nowadays
that prevent us from seeing each other
as often as we’d like.

Wishing you as much happiness on
your birthday this year as we used to
have together growing up!
Girl, each year you become more
beautiful and more fabulous than
ever before! I'm just hoping that's
something that runs in the family!

Happy birthday to you!
Happy birthday, my sis from another miss!

I’m truly blessed that we’re related, but even if we weren’t cousins we’d still be best friends until the end of time. You really do mean the world to me, my dear.
Happy birthday, cuz! Not only are you a great blessing to our family, but you also mean more to me than you’ll ever know.
Happiest of birthdays to you, cousin!

Seeing as you’re just as close to me as
a sister, I feel I can be honest with you
about anything.

So, I’ll just come right out and tell you…
I totally forgot to get you a gift this year!
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!
