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


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

Happy birthday, 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.
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 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!
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!
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!
Wishing my sister at heart the
happiest birthday possible today!

Love you, my dearest cousin!
Happy birthday to a unique
Cousin who’s as funny as you
I’m thankful for the laughs
And your true friendship, too!
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!
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!
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!
