Small but mighty: NICU babies at Boston hospital celebrate National Superhero Day

Wonder Woman, Superman, Batman, and Captain America don’t often get together, but their infant counterparts were spotted Friday in the NICU at a Boston hospital.

In celebration of National Superhero Day, the nursing staff at Brigham and Women’s Hospital decked out some small but mighty heroes in hand-knit superhero costumes.

Brigham and Women’s Hospital is known for dressing up its newborn patients.

Earlier this month, babies were recently happy to don some Easter apparel. They also dressed up for Valentine’s Day and Christmas.
