World's tiniest babies: How are they now?

Babies are the world's smallest people - so what happens when they are born premature? Preemies enter the world in fragile condition, often weighing much less than full-term babies and facing health problems because their organs have not had enough time to develop. As a result, they need special medical care in a neonatal intensive care unit (NICU).

How do premature babies fare as they grow up? It all depends. Two of the tiniest babies ever born have beat long odds and are growing up healthy today - one, Rumaisa Rahman, a healthy first-grader, and the other, Madeline Mann, an honors college student. Another preemie - believed to be the world's third-tiniest - Melinda Star Guido, is just about to embark on life outside the hospital.
