Sheryl Crow has unveiled newly adopted son Wyatt to the world. The singer gave interviews to OK! mag and USA Today about 3-week-old Wyatt from her Nashville home and says she is hoping to add "a whole troop" brothers and sisters to the family. "The day he came home, I felt like the whole house had changed. The house felt fuller," Crow says. "You just feel like nesting and making sure he's acclimated to the world. It is all so fascinating... My mom would hand him to me and say, 'Here's your mommy.' It was really poignant (and very startling) to hear my mom call me Mommy. It took me a while to get used to it." Crow went through a closed adoption and had took custody of Wyatt within 24 hours of his birth. "I love the idea of adopting. I always thought I had an immense amount of love to give," says the singer, who has lots of help from famous friends, including "Earth Mother types" Laura Dern and Gabrielle Reece, who "are really dialled in to how to raise a baby organically and holistically." Crow plans to raise Wyatt in Nashville, rather than LA, and he will go to school in Tennessee. Of her single status, the singer says she doesn't "feel any pressure to get married," and though she has "somebody" in her life, she says, "I'm not walking down the aisle." Crow's favorite moments with her son? "Waking up in the middle of the night and seeing him next to me and realizing, 'Oh, he's still here! How fantastic! It's not a dream.'"
