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


Take a really deep breath, cousin, because you’re going to need all the air in your lungs to blow out so many candles today!

Happy birthday to you, my dear!
My sweet cousin, you’re as dear 
and meaningful to me as any sister
and just as annoying as one, too!

May you have a fabulous birthday!
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!
Sure, getting lots of gifts on your birthday
is nice but no gift will ever be as great as
simply having a wonderful cousin like me!

Happy birthday, girl!
Age might not be your friend, cousin, but I always will be! You can always rely on me for sisterly support no matter how old you get!
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!
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!
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!
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!
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!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
Happy birthday! Your birthday is always a
pleasing time for me as it reminds me that
you’ll always be older than me, cousin!
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!
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 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!
