WILLIAM BRANGHAM:

For the last few months, we have been following several moms and their premature babies through this process.

Neonatal intensive care units give these children a better shot at survival now than at any other time in history. In the early '90s, a child born as early as 23 or 24 weeks was unlikely to survive. Now they routinely do.

But, despite that, leaving the womb so early still puts these kids at high risk for emotional, behavioral and developmental challenges. This intervention is meant to help minimize those impacts.
