Daughter-in-Law Birthday Wishes: What to Write in Her Card

First of all, a birthday message for your daughter-in-law doesn't have to be specifically about your relationship to her. You can write your message in any style that you think will fit her personality. You can write a birthday poem, a birthday quote, or even a Christian birthday message if she's religious.

If you're looking for ideas about what to write in your daughter-in-law's birthday card, the examples below may help. These messages are specifically tailored to the "in-law" relationship.
