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


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!
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 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!
Happy birthday to a unique
Cousin who’s as funny as you
I’m thankful for the laughs
And your true friendship, too!
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.
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, 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!
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!
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!
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!
Happy birthday to my 
fondest family member!

A cousin to me you are
But you will always be 
More of a sister, by far!
If I didn’t know any better I’d never guess it was your birthday today as you don’t look a day older, let alone a year! Happy birthday, my beautiful cousin!
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!
Happy birthday to my favorite cousin!

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