Gwen Stefani and Gavin Rossdale's youngest son was injured in a Thursday night accidental fall that his father called "horrific."
Zuma Rossdale, 2 1/2, broke his right arm in an accidental tumble from a countertop, his father told People.com.
"It was one of the worst nights of our lives," Gavin told People Saturday in Las Vegas.
Never fear, little Zuma is doing well after being treated at a hospital. "He's fine now," Gavin told People of the frightening experience. "It's almost worse for us [as parents] ... The kids are never alone and you turn your back and it takes a split second."
