Your child is all grown up and has already said "I do" to someone special. With that comes a new family member: your daughter-in-law. If she has a special day coming up, taking the time to write birthday wishes for your daughter-in-law is a gesture she'll appreciate. Whether you send greetings in a card or a simple text message, she'll know that you're thinking of her—and that's what counts. You can also pair your handwritten note with a thoughtful daughter-in-law gift to finish things off nicely. Need some help composing a birthday message for your daughter-in-law? We're here to help you find the right words to show your affection. From sweet sayings to heartfelt greetings and even a poem (yes really!), here are our favorite daughter-in-law birthday wishes.

What to Write in Your Daughter-in-Law's Birthday Card

The secret to writing a winning birthday message for your daughter-in-law comes down to two things: her personality and the relationship you two share. If she's sentimental and likes to save her birthday cards, a heartfelt note is guaranteed to give her all the feels. On the other hand, if she's always joking and making people laugh, consider a funny birthday greeting that plays to her sense of humor.

You can also think about the connection you have with your daughter-in-law. Is she new to the family? Are you her mother-in-law or father-in-law? If you're still getting to know each other, you can keep your birthday sentiments to your daughter-in-law short and sweet. Or, if you're super close, a more personal approach—like reliving a fond memory or complimenting her on something specific—will strike the right note. Ultimately, you'll want your daughter-in-law to know you cherish her presence in your life (and your child's, of course.)
