Happy family of four! New Girl's Max Greenfield and his wife, Tess Sanchez, have welcomed their second baby, a boy named Ozzie James Greenfield, E! News reports.

Born on Monday, Aug. 24, baby Greenfield joins big sister Lilly, 5.

Having already gotten the first-time parenthood jitters out with Lilly, Greenfield, 34, anticipates his second round of diaper duty is going to be a breeze. "You know, it's the second one. With the first one, you have the nursery set up when you find out that you're pregnant. 'Let's do it!' This one, you're like, 'It will be fine. We'll figure it out.'" he told Us at a Chrysalis event in June.

Once their new baby comes home, Greenfield is prepared to put big sis Lilly to work. "We're really hoping that she can pick up some of the responsibility slack. We're going to put her to work and we're going to see how well that goes," American Horror Story's newest guest star half-joked to Us. "Whatever she can do!"
