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

Happy birthday, my dear!
My dearest cousin, you are
the sister I was never lucky
enough to have and I wish
you only beautiful things
on your very special day!

Happy birthday!
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!
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!
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!
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!
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!
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!
