90+ Heartfelt Birthday Wishes for Your Sister-in-Law


Happy birthday, my dear. I hope you know that you didn’t just become an extended family member to me, you became a sister as true as can be.
We are sisters 
Through and through
A deep bond we have
Me and you
I’m so grateful that the 
Universe brought you to me
Even if not from birth
We were destined to be.

Happy birthday, my dear.
My wish to have a sister has come true, for now I have you. So I wish all your wishes may come true on your birthday, dear sis-in-law!
Happy birthday, my darling!

We may not be blood-related,
but to me, you are as much
of a sister as if we were.

I think of you much less as
an in-law and much more
as just a sister.

May you always be as happy
as you make my brother!

Kisses!
You aren’t simply a wonderful friend and sister-in-law to me, you’re my true sister at heart. I am so grateful to have you in my life.

Happy birthday.
Happy birthday to my brother-in-law
who just so happens to have the
world’s best sister-in-law!

Have an awesome day today, bro!
Growing up I always wanted a sister. A best friend for life and someone I could share my deepest thoughts with. I asked God many times to bless me with a sister, but the message must have been lost somewhere along the way since I only got a brother.

The years went by and this wish completely vanished from my mind. But one happy day my brother found for himself a wonderful wife, a beautiful person, who, with time, would be a sister to me.

To my sister-in-law, my dear sister, the sister I always wished for, I wish the most amazing of birthdays!
