What to Write

Visit any store and you'll find plenty of birthday cards with expressive poems and warm well-wishes. However, to truly make your daughter-in-law feel appreciated on her birthday, adding a sincere and personal birthday wish to the card will show her you care and acknowledge her important role in your family.

First, consider your daughter-in-law's personality. Is she the life of the party, always inspiring everyone around her to laugh and have fun? Then consider going with a funny birthday greeting. If she's sentimental and likes to save her birthday cards through the years, go with a more poetic and heartfelt "happy birthday" to your daughter-in-law.

Also consider your relationship with her. Is she new to the family? You may want to keep your birthday sentiments to your daughter-in-law simple, but earnest, as you build your new relationship. Don't be afraid to get personal, especially if she's been in the family for years. While you didn't raise her, you do share a unique bond. Bring up a fond memory you shared from a family vacation or holiday. Compliment some of the specific things you love about her, such as her delicious cooking, chic style or witty jokes.

Whether you go simple or sentimental, a happy birthday wish can show your daughter-in-law your love and admiration for her. Feel free to use our ideas as inspiration or copy them word-for-word. As long as it's in your handwriting, your daughter-in-law will know it's coming from your heart.

Heartwarming Birthday Wishes

We won't lie: New in-law relationships are tricky to navigate at first. But if you've made it to the other side with a close bond, your daughter-in-law's birthday is the perfect opportunity to express a heartfelt message showing your gratitude for her.

Simple Birthday Wishes

Sometimes less is more. There's nothing wrong with keeping it simple. If you're adding these daughter-in-law birthday wishes as a sign off to an already-thoughtful greeting card, you only need a few words to add your personal touch.

  • Happy birthday to my fantastic daughter-in-law!

From Her Mother-in-Law

There's two women your child loves most: their mother and their wife. And you both give that love right back. Having that in common definitely serves as a strong foundation for a close bond between you (the mother-in-law, or whatever she may call you) and your daughter-in-law. If you're lucky enough to have a close friendship with her, celebrate her special day with one of these birthday greetings.

  • Cheers to you, daughter-in-law! Let's celebrate with a birthday brunch on me soon!
  • To me, you are more than just a daughter-in-law. You're also a great friend and cherished family member.
  • It's so fun having you as a daughter-in-law. I appreciate all the memories we've made together and can't wait for the memories to come!
  • Being a mother-in-law is easy with a daughter-in-law as sweet, smart and thoughtful as you.
  • Today is all about celebrating you. Cue the cocktails and cake!

From Her Father-in-Law

You may not be her biological dad, but as a father-in-law, you still play the important roles of handyman extraordinaire, advice giver and dad joke expert. Win some brownie points by sharing some birthday sayings with your daughter-in-law that'll show her she's special.

  • Our [son/daughter/child] is lucky to have you as a wife. Thank you for being part of our family!
  • I never knew I'd be the father-in-law to such a special person. Happy birthday!
  • Happy birthday! It seems like just yesterday you were a whole year younger.
  • Raise a glass to the best daughter-in-law I could ask for. Enjoy your special day!
  • Thank you for being a great daughter-in-law. I think the other father-in-laws are jealous!

For a Future Daughter-in-Law

If she hasn't officially reached in-law status, you can still say a sincere "happy birthday" and show her your excitement for her to be part of the family. Keep it short and sweet to avoid scaring her back up the aisle. (And don't feel too pressured to buy a gift just yet—we're sure you had that covered with your parent engagement gift. A sweet note will do just fine.)

  • We're so excited for you to join the family and celebrate many birthdays to come.
  • Planning a wedding is stressful. I hope you are able to relax, unwind and have fun on your birthday!
  • Happy birthday to my [son/daughter/child]'s other half.
  • I hope the future holds a lot of happiness, love and success for you. I can't wait for the big day!
  • We love how happy you make [your child's name]. I'm so thankful and lucky you are joining our family.
