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!

When I was a kid, I always complained about the fact that I didn’t get to have a sister. But now that you are a part of my family, I have found the sister I always wanted in you. Thank you.

With the sun shining and birds singing to match the smile on your face, I send my wishes dear sister-in-law.

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!

May your belly be full of cake, your hands full of presents, and your heart full of compassion, happiness, and joy. Happy birthday to my phenomenal sister-in-law!

Having a sister-in-law made me stronger. I have always thought that I am alone with my struggles as a home maker. However, I got my sister-in-law who shares the same experience. I can count on her for advice, while I also do the same for her. You are indeed a gift and a blessing in my life. Wonderful bday to my ever beautiful sister-in-law!

Today is more than a celebration of when you were born. It is a celebration of the wonderful life you have lived so far. May you continue to have bright and happy days.

I’m glad that you have become my sister-in-law because now Mom and Dad can harass you for grandbabies instead of me! You have my heartfelt gratitude and love. Happy birthday!

In times of emotional whirlwinds, you are there as my shoulder to cry on. In times of trouble, you are there to back me up. Thank you for not only being my-sister-in law, but also a friend that I can always count on. Happy birthday!

Thank goodness you married my brother, because now you can take over the job of spoiling your nieces and nephews. He does a great job, but I know that you are going to be even better at it because I’ve experienced being spoiled rotten by you first-hand!

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!
