Madonna Poses With All Her SIX Children

Madonna is celebrating a special moment in the best way possible. It's been one year since the singer opened the Mercy James Institute for Pediatric Surgery and Intensive Care in Blantyre, Malawi -- named after her Malawi-born daughter, Mercy, 12 -- and on Monday, she returned to the country, this time with all six of her children.

In addition to Mercy, Madonna is also mother to Lourdes, 21, Rocco, 17, David, 12, and 5-year-old twins Estere and Stelle.

"Tree of Life.....🌴 Mercy James Pediatric Hospital! 🏥 One Year Later!" Madonna captioned an Instagram pic of her and her family posing for a pic inside the institution. The 59-year-old singer also shared a photo of herself in scrubs, writing, "In my Scrubs in the Mercy James ICU ward with my hero Dr. Borgstein #savinglives 1,639 surgeries this year."
