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


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!
Happy birthday, cousin!

On your special day this year, I just wanted to tell you how much you mean to me.

After all, we share so much more than simply the same family; we also share lots of secrets and unforgettable moments from our childhood! 
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!
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 you!

If I had to give just one reason why you’re more like a sister to me than a cousin, it would be that growing up together you would annoy me just as much as any sister would!
I hate to be the one to tell you, cuz, but good looks don’t last forever! At least you had a good run!

Happy birthday to you 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!
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 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 
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 my witty sister-like cousin!

Spending so much time with me must have rubbed off on you, as you’re funnier than ever now!
