Double the children double the trouble! Today is an exceptional day for me as it is not only the birthday of the love of my life but also of the sister that came out right with him! Happy birthday
This family had a surprise for me since meeting you for the first time made me think I had issues with my sight, seeing everything on the double! Who would know that this double would turn out to be the most amazing sister in law ever! Happy birthday
When I first met my husband/wife, I thought that I had found the perfect person on Earth, then I met you and realized that the top spot is shared! Happy birthday to the greatest sister in law
I know that we haven't been on the best terms recently, but if I'm able to love a person so much, then I'm confident I can use this special day as an excuse to start loving his/her sister. Happy birthday
We may not always see eye to eye, but we must use the love we share for your brother/sister and make this special day a new beginning for our relationship! Happy birthday
Getting to know you at first was a rough deal, but I'm sure that in the process we will find common ground on the one thing we both love endlessly. Happy birthday
Having you as my sister in law made this family just a whole lot better! With your infinite wisdom and feminine grace, you have made not only my husband but also our children better people. Happy birthday
You were always there when we needed your help and supported us in both the good and the bad I could not have wished for a better sister in law! Happy birthday
You have been like a mother to my husband and a teacher to our children. It is times like these that make me think that our family would not have been the same without you. Happy birthday
