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


Don’t worry about getting older, my
dear cousin!

It happens to us all but luckily for us,
we have great genes that should see
us age more gracefully than others!
How fortunate are we!

I hope you have a birthday that’s as
beautiful and fabulous as you are!
Officially you’re my cousin, but my heart
says you’re my sister. Luckily for you, I
always listen to my heart!

Happy birthday to you, my dear. I
hope you have a truly wonderful time
celebrating your special day today!
My darling cousin, congratulations on yet another incredible year!

I’m a strong believer that blood is thicker than water, and particularly in our case, it couldn’t be any more accurate! Our bond is so close, more likened to that of sisters, and I wouldn’t change that for the world.

Have a truly wonderful birthday, my dear! You deserve it more than anyone!
Wishing a happy birthday to a sister-
like friend and person like no other:
my dearest cousin!

Have a fabulous day, my lovely!
Wishing the absolute best birthday
to my true sister at heart!

You may be my cousin but you far
surpass that, to me you’ll always
be much more like a sister!

Enjoy your special day, my dear!
Lots of love, big kisses and
enormous hugs to you!
Happy birthday to my dear cousin!

I’m so grateful to have had you in my
life since we were kids! 

You are everything I could ever wish
for in a cousin and more. In truth, I
have always seen you as more of a
sister figure in my life than a cousin.

I hope that you know you can always
rely on me, the same way I know I
can rely on you!

Have a fantastic birthday, sis!
Wishing a very happy birthday to my
favourite cousin today!

You’re like a little sister to me, and you
always remind me of myself when I was
your age! It’s wonderful to see that you
are such a happy kid, living an enjoyable
childhood just like I did!

I wish you many more happy years and
that your smile never fades! Sending
you lots of love and big hugs on your
special day, sweetie!
Happy birthday to the most gorgeous chic!

I want you to know you’re not just my
cousin but more like a sister to me!
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!
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!
I didn’t think it was possible since you’re already pretty awesome but with each passing year, you just keep getting better and better!

Happy birthday, my sweet cousin!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
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 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!
