Keys: Parenthood is a joy

Alicia Keys

named her son


after a life-transformative trip to the African nation. Turns out the 2-year-old has been as soul-making as his namesake. "Being a parent has made me more open, more connected to myself, more happy, and more creative," Keys tells Scholastic Parent & Child mag. "I'm more discerning in what I do and how I do it. It's just made me a better person all the way around."

Keys, who is doing p.r. for her interactive storytelling app, The Journals of Mama Mae & LeeLee, says her son's quite the young singer. "We're always singing together," she says. " 'Twinkle, Twinkle, Little Star,' 'The Hokey Pokey,' 'Happy Birthday,' and we like one of my songs, 'New Day.' That's Egypt's favorite."
