For Sandra Bullock, motherhood is practically magic.

This year, the 61-year-old shared an ultra-rare look at her two kids, son Louis, whom she adopted at three years old in 2010, and daughter Laila, who joined the family in 2015 when she was just over two years old.

“To all the mamas,” Sandra captioned her May 10 Instagram post, “No matter how you came to be, Happy Mother’s Day. We are all bound by this honor of a lifetime.”

Accompanying her caption was a throwback image of Sandra and her two kids. In the sweet snap, Louis sits in his mom’s lap in a top hat and cape, while Sandra holds Laila in her arms, the then-toddler dressed in a sunflower dress.

The Practical Magic actress also included two other poignant pictures in her roundup—the first with her grandmother and a second with her mom Helga Mathilde and sister Gesine Bullock-Prado.

“Mom and Omi, thank you for teaching me. We miss you,” she continued, before teasing, “Sorry I was such a brat.”
