It's every parent’s absolute worst nightmare. Your young child has an illness. A serious illness, one that might take his or her life. In the case Tammy Krause, the child was her daughter, and just 5 years old. Gabby Krause was found with a malignant tumor in her head one day before her 5th birthday. She left the world not long after. Gabby Krause would leave the world- but she also left the world a gift. A gift her mom Tammy carries on to this day. Tammy Krause is my guest this week on Amazing Americans.
