Duhamel said he and his spouse have agreed to schedule their work engagements so they can spend as much time together as a family as possible.
"I can't imagine having a kid and then not being able to be there -- that would just drive me crazy. My head would be at home with mom and baby," he said. "We want to work it out so that we can be together; whether I am working, they can come with [me] or if she is working I can go with them. I can't see myself ever wanting to be away from my wife and kid."
The couple married in 2009 and announced Fergie's pregnancy in February.
