3. “I’m so happy you are a part of my life”

4. “You are more than just an in-law to me…”

This is an especially sweet message for your mother-in-law’s Mother’s Day card. You never want your mother-in-law to think you care just because you are married to her child. Let her know how much you care and write down your true feelings in the sweetest way.

5. “I appreciate you for so many reasons…”
