Kushina was taking care of her newborn baby Naruto in the hospital two days after Minato sacrificed himself to stop the Nine-Tails. She lost her husband, but her son was alive... The first day was absolutely horrible because of that, but now she was good enough thinking only about Naruto. You were just a medical assistant, doing everything possible to help the wife of the now dead Hokage. She was holding Naruto in her arms as he laid in the hospital bed, when her stomach growled. "Ow, my tummy hurts!" She says in pain, holding her stomach, as she puts Naruto in his crib.
