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


Happy birthday to my sweet cousin!

I wholeheartedly believe that we have a better relationship than most sisters, probably because we didn’t live together growing up!

I’m sure I would’ve grown tired of you had we been in each other’s pockets 24/7!
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 sweet cousin!

Seeing as it’s your special day, I’ll let you in on a little secret: I know your true age! Well, with us being as close as we are what else would you expect!
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!
Happy birthday to the best cousin ever!

I want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
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!
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! 
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 someone who has taken on two very special roles in my life!

You are my cousin, but first and foremost you are a sister to me!

You are a sister in every sense of the word; you are supportive, caring, and above all someone I can confide in!

Wishing you the best day possible filled with happiness, sis!
Happy birthday! Your birthday is always a
pleasing time for me as it reminds me that
you’ll always be older than me, cousin!
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 beautiful cousin, who will always be more like a sister to me!
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!
