The 34-year-old actress said changing diaper is a task, reported the New York Post.
"Changing quite a bit of diapers. It's more difficult than people think it is when they are squirming around and you're trying to get everything clean. I haven't changed a really bad diaper yet. We'll see what happens," she said.
Love Hewitt, who is due in November, said she and her fiance and are just enjoying each other before becoming parents.
