SAN DIEGO — UC San Diego Health’s neonatal intensive care unit at Jacobs Medical Center celebrated the season by showcasing what they called the cutest miniature trick-or-treaters ever.

The unit’s NICU babies played dress up for Halloween as a fun way for parents to bond with their infants, said Michelle Brubaker, Associate Director of Media Relations at UC San Diego Health. She explained this also brought smiles to the doctors, nurses and staff who provide them with care.
