50+ Happy Birthday Wishes for Sister from Another Mother


You might not be my biological sister, but deep down in my heart, you're the truest sister ever to exist.

Happy birthday, my special sis!
Another birthday already, girl! What

No matter how old we get, we’ll always
be there for each other and you’ll forever
be my favorite gal pal.

I hope you enjoy your special day, bestie.
Happy birthday to you today, sis!

We may not share the same mother but that makes no difference to me. You are more caring, supportive, and loyal than many full sisters out there!

No matter what, you will always be the most complete sister to me.
To my very best friend in the whole world,
my confidante and dear sister at heart, I
am wishing you the most wonderful
birthday ever today!

Always know that you are my family, and
the small fact that we come from different
mothers doesn’t make you any less of a
sister to me!

Big hugs to you on your special day!
You’re more than just a great friend to me;
you’re a true sister in every sense of the
word. You give me the confidence and
courage to stand for what I believe in and
you encourage me to pursue my dreams.

Without you by my side, I wouldn’t be
nearly half the person that I am.

I’m sending all my love to you today on
your special day!
Happy birthday to my sister from the same mister! I’m wishing you all the happiness in the world as you celebrate your special day today, sis!
Few friends are like sisters
And few friends are like you!

Your mother is like my mother, which must make us sisters! We’ve been there for each other through thick and thin, and you’re my best friend in the whole world.

I wish only happiness for you always, dear!

Happy birthday!
The very best friend 
I could wish for
So kind and so true
Will always be dear to me
A soul sister like you. 

Happy birthday, bestie!
Happy birthday to my true soul sister, my dear gal pal for life.

The fact that you came into this world from another mother is the one and only thing that sets us apart from biological siblings, and you’ll always be able to quote me on that.
I’m wishing you a happy birthday today, bestie! Well, as happy as it can be considering you’ve just got another whole year older!
Happy birthday to my sister-like friend and bosom pal! The only way we could be more like sisters is if we had actually been born by the same mother!

bestie. Happiest of birthdays to you.
A gal pal like you who
Is so funny and sweet
Is more like a sister
Than anyone I’ll meet!

Happy birthday, my
Sister from another!
Happy birthday to the one person in
the world I could never be without!

another, and you continuously manage
to make each day brighter than before!
