Margaret Laura "Mila" Hager
Margaret, Jenna and Henry's first child, was born on April 13, 2013. Although the little one — who is Former President George W. Bush's first grandchild — goes by Mila, her first and middle names carry lots of meaning for both Jenna and Henry, as she's named after her grandparents: Margaret "Maggie" Hager and Laura Bush.
On her seventh birthday, Jenna shared a photo of her oldest child on Instagram with the sweet caption: "Happiest 7th Birthday to our Mila! Named after both your grandmothers, you have their love of life, love of books and love of laughter. Your empathy and kindness amaze. I hope you never have to guess how loved you are because our love for you is infinite!"
