In the 1973 movie Sleeper, Woody Allen, about to die from complications of peptic ulcer surgery is wrapped in aluminum foil and frozen. When it was defrosted, the body was healed as a result of two centuries' worth of medical advance.
Your baby's Stem cells are frozen for 20 years. In some sense it is a real sleeper.

When Ehlert's leukemia was diagnosed, the cancer was already in its chronic phase, dangerously close to what is known as the "blast" phase. For 30 days, Ted Ehlert searched for lifesaving bone marrow that would match his own, none provided a match. Less than three years ago, this failure to find a bone marrow match would have signaled the end of the road for Ehlert. Fortunately, Ehlert's cancer hit at a time when he could undergo a stem cell transplant with blood taken from an umbilical cord. A year and a half later, he can say he's cancer-free.
