When asked are they planning to have another baby soon, Kerr said: "I love motherhood. Someday, but not right now."
The 29-year-old, who married the actor in 2010, said that despite the huge amount of travelling, they try to make sure their son Flynn sticks to a schedule and enjoys a normal childhood, reports contactmusic.com.
"We have the schedule planned out for him. We make sure he is doing his play dates, he is doing enough reading time, he is doing enough drawing and painting, arts and crafts and also a lot of fun time.
"We like to dance. You know, turn the music up, dancing around the kitchen. It's one of our favourite pastimes," she said.
