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


If you weren’t my cousin
You would be my sibling
As you truly are my sister 
Just from another mister!

Happy birthday, my dear!
For a cousin and a sister all rolled into one
I’m wishing you a birthday that’s full of fun!

that are still waiting to be written!

you the very best on
your special day today!

Deep down in my heart
you are my sister, even if
officially you are my cousin.

You are such a beautiful soul
and I wish for nothing but the
best in life for you, as you truly
deserve it.

I hope you have the most fab
birthday ever!
Families are filled with many magnificent wonders, but there are few things as wonderful as being blessed with a truly precious cousin.

You must feel pretty lucky to have that in me!

Happy birthday to you today, my dear!
I wanted to get something extraordinary 
and particularly special for a cousin 
who is more like a sister to me, 
but then I realized something:
You already have all of that in me!

I hope your birthday is as wonderful and 
as meaningful as you are to me, my dear! 
Wishing a very happy birthday to you!
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!
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!
Laughing at each other or laughing
together, you’ll always be the person
I’ll most enjoy sharing life’s funniest
moments with!

Happy birthday, my sweet cousin!
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!
We must be related because you have so
much style and sophistication just like me!

If people didn’t know any better or that
we’re cousins, they would definitely think
that we’re sisters!

Happy birthday, my dear! I hope you enjoy
your special day today!
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 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, 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 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 my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
