Mom to son Cree, the star of STYLE's Tia & Tamera has plenty of advice to offer her pregnant twin sister and other expectant moms. "When the baby comes, your natural instincts are going to kick in," she assures. "If you were a worrywart before the baby comes, you'll be that way when the baby comes, but follow your instincts. I spent hundreds of dollars on classes that teach you how to feed a baby, swaddle them…and you really don't need to take classes. You'll pick it all right up."
