With his wife, a photo editor at Sports Illustrated, due "in a week or two," the former Ed and Love Monkey star is otherwise prepared.
"We're loaded up, We're ready," Cavanagh told PEOPLE at the Cinema Society and Brooks Brothers screening of 500 Days of Summer, held Thursday evening in Manhattan.
The new baby – who does not yet have a name – will join older siblings Tommy, 2, and Alice Ann, 3 ½. Cavanagh and Grise have been married five years.
The actor, 45, recently appeared on TNT's Trust Me opposite Eric McCormack. His latest project, hosting the Smithsonian Channel's Stories From the Vaults, premieres July 12 at 8 p.m.
