Little Ryleigh is a nothing short of a miracle baby. Her mom, Rebekah Gregory, survived the Boston Marathon bombing. That fateful day four years ago changed Rebekah's life forever. Her leg had to be amputated and doctors told her something truly heartbreaking: She would never be able to have another child because her body, which had been riddled with pieces of metal, had been too traumatized. Rebekah already had a son, Noah, but she and her husband, Chris desperately wanted another baby.
