Bring out the protective body suit.

Adding a fourth child to the family this fall, Matt Damon says he’s happy to be used as a punching bag for wife Luciana to release her discomfort as they head into the home stretch.

“We’re in the third trimester and basically I’m just dodging punches right now from my wife,” Damon told PEOPLE at the premiere of Hereafter at the Toronto International Film Festival on Sunday.

“That means I have to work on my defense and I never know when a left hook or a right cross is going to come. She’s completely over me and over being pregnant.”

Lucy may not find him so appealing due to fatigue and back pains, but the Invictus star, 39, is sympathetic to what she’s going through.

“She’s been a great sport,” says Damon. “She looks amazing and she’s taking great care of herself.”

Already a full house with three daughters — Alexia, 11, from Luciana’s prior marriage, Isabella, 4, and Gia, 2 — Damon says he’s indebted to the missus for having their children together in such a short period of time.

“She’s been pregnant basically for more than half of the last five years and she’s been nursing the other half so I’ve definitely asked about as much as I can from my wife,” he laughs. “Now I’m all hers!”
