50+ Happy Birthday Wishes for Sister from Another Mother


We may not have been born siblings
but somewhere along the way,
we became sisters anyway.

Happy birthday to my true sister at heart.
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!
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 never knew someone could be so much like a true sister to me and touch my heart as much as you have. You truly are my sister from another mother.

I’m wishing you a lovely birthday, my dear.
