      It was a mother's worst nightmare: On March 23, Huyen Pham put her healthy 4-month-old baby, Donovan Tran, down for his nap. He'd been throwing up, but after all, he'd just started on solid food, and she reasoned that maybe that was hard on him.

      An hour later, when she checked on him, he was limp as a ragdoll, pale and unresponsive. "I thought he was dying," she says.
