If you have a sister-in-law, then you will know the joy of being gifted with a sister a little bit later in life. For many people, a sister-in-law means a special lifelong friend that can be turned to for advice in difficult times, and belly-aching laughs in good ones. You also celebrate many of life’s milestones with your beloved sister-in-law.
When her birthday comes around, it’s important to let her know just how happy you are that she’s part of your family. Although she may not have shared your childhood, she will be around for a long time to come.
Feel free to adapt them in any way that you see fit so that your sister-in-law’s birthday message is one that will mean the world to her.

How to Say Happy Birthday to a Sister-in-Law
Personalized birthday wishes are always a lot more special than generic ones are, and your sister-in-law is bound to feel wonderful after reading hers. Below are three simple tips on how to personalize her birthday card:
• Most of us have nicknames for the people close to us. If you have one for your sister-in-law, use it in the card. By addressing the card to her nickname, she will immediately be reminded of the special bond that the two of you share.
• What makes your sister-in-law special? What makes her shine out from other people? Perhaps she is a great mother, perhaps she makes your sibling happier than you could ever have imagined, or perhaps she is excellent at giving advice. Either way, try to include something in the card about what makes her so special. Make sure that whatever you write to your sister-in-law comes straight from the heart. This could just be a personality trait, or perhaps even a memory that you treasure most. Including it in her birthday card will make for a heart-warming moment.
• If your sister-in-law has a special nickname for you, be sure to sign the card with that nickname. This will pull the card together quite nicely and reinforce the idea of the bond that the two of you share – what could be more special than that?
When composing your birthday message to your sister-in-law, don’t rush into it and write something that you don’t mean.
Sit down, relax, reflect and take your time with it. The more effort you put into the card, the more she will love it. It’s the thought that counts, after all.
