Now that my brother is married, he seems to have lost his spot as the family favorite. I’m not sure if my parents or I love you more, but either way, good job uprooting my brother! Thank you, and may your birthday be full of scrumptious food and delightful people.

The best thing about having you as a sister-in-law is that we didn’t have to suffer through that awkward growing up together stage. Instead, we got to skip straight to the good part: being friends. Happy birthday to my “sister” and friend!

We may be different in many ways: different viewpoints, different personalities, and different beliefs. But there is one way in which we are completely the same: we both love and respect each other regardless of our differences because family always comes first.

Thank you for giving me something that my parents never did: a sister. You mean so much to me and are an invaluable part of my life. May your birthday magical and bright.

You’ve brought so many wonderful things into my life: sisterhood, friendship, and love are some of my favorites. I hope you have a lovely, lavish, and light-hearted birthday.

Sister-in-Law, you always seem to be on top of everything, and you never seem to age. It’s like you are a magician. So, can you do me a huge favor and make my brother disappear? Thanks!

Not only you are like a sister to me, but you are also a wonderful adviser and best friend. Best bday, sister-in-law!

Happy birthday to the only woman brave enough to marry my brother! You are my hero. May your birthday delight you and your joy be immeasurable this year.

When I got married I feel like I won the jackpot with having you as my sister. Happy birthday I love you so much.

Sister in laws are like muffins in a bad day. They make you all warm and fluffy inside, chasing the bad vibes away.

I always wondered how my husband came by his genuine, loving, and respectful ways, and now I know: he grew up with an amazing older sister who taught him to treat women with respect. Thank you, and happy birthday!

I am so thankful that you found your way not just into our family, but into our hearts as well. You always bring a smile to our faces, and we are blessed to have you in our lives.

You are like a soft breeze in a warm summer day – gentle and cool. Wonderful bday, sister in law!

After I met you I realized something: my wife must have learned her tenacity, strength, and charm from her older sister! Thank you for being a spectacular sister to both of us.

I adore you as a person, confide in you as a friend, and love you as a sister. You make my life better with your presence, and I hope that you always feel surrounded by peace and love.

Wonderful bday to you my amazing sister, you are the greatest gift that life gave to me after marriage.

I couldn’t have asked for a better sister-in-law, because you are calm, cool, and captivating. How my brother managed to trick you into marrying him is still a mystery to me, but I am glad you fell for whatever it was! Happy birthday to my remarkable sister-in-law!

Sister-in-Law, there are several things that I want to take the time to thank you for: for always letting me confide in you like a real sister, for comforting me when life wasn’t going my way, and for loving me as much as you love my brother. I am eternally grateful to have you in my life.

My niece and nephew are blessed to have a wonderful mom like you. They can eat your awesome cooking everyday and take them trips to awesome places! Of course, I know that you never forget to tag me along. Thank you for not only being my sister-in-law, but my older sister as well. Best birthday!

When my older brother married you, I was worried he wouldn’t have time for me anymore. But I couldn’t have been more wrong. In fact, we are closer than ever, and instead of losing my brother, I have gained a new friend. Thank you, and happy birthday Sister-in-Law!

To the person with so much love and care for all the people in her life – wishing you a journey ahead filled with happiness and hope. Happy bday, my sister-in-law!

I don’t need Facebook to remind me that it’s your birthday, Sister-in-Law. Who could ever forget such a talented, intelligent, and beautiful woman’s birthday? May your day be truly spectacular.

She is like your sister from another mother. A friend and someone you can chat a lot with when it comes to raising your kids or get ideas on how you are going to surprise your husband to celebrate his latest job promotion.

I’m often jealous of my brother because he gets so much of your time. He should really share you more! Happy birthday to my magnificent, spectacular, and marvelous sister-in-law!
