On Saturday, families, doctors and nurses honored the "tiny graduates" and celebrated their journeys to a healthy life at the fourth annual Neonatal Intensive Care Unit Graduation Celebration.

"We've seen over 1,600 graduates since the NICU was established," said Candice Monge, chief nurse executive officer. Nearly 200 graduates and their families were expected to attend this year, making this reunion the largest, she added.

The NICU opened in 2010 with eight beds. In 2012, it moved to a new building and expanded to 21 beds.
