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!
My dear, I am wishing
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!
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!
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!
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!
I hope everything you wish for comes true for you today, cousin, but really what more could you want other than a wonderful family member like me!

Happy birthday, girl!
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!
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!
If I didn’t know any better I’d never guess it was your birthday today as you don’t look a day older, let alone a year! Happy birthday, my beautiful cousin!
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 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 my beautiful cousin, who will always be more like a sister to me!
Happy birthday to you, my dearest cousin!

Another year older and wiser, or I suppose
just older in your case!

Don’t worry, though! You still have many
years to come where you can learn from
me and gain some of my wisdom!
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!

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!
