The Australian supermodel, who married Pirates of the Caribbean actor Bloom last year, said that they are constantly travelling with work at the moment but would like to choose a country to settle in eventually for the sake of their 10-month-old son Flynn.
Kerr told Hello! magazine: "When Orlando is working, I make sure I'm not working. So whenever he has to go to New Zealand, where he's currently filming The Hobbit, Flynn and I go with him, too. Then, when I'm working, he makes sure he's off - so there's always at least one of us with Flynn.
"It's great that we have these few years when we can travel before Flynn has to go to school. I don't know yet where I'd like him to go to school, though. It's going to be hard to choose - he has three passports: British, Australian and American. 'Officially' he's American, which both of us find amazing."
Kerr also revealed that she likes to visit her family in Australia "at least a couple of times a year", adding that she hopes that the three of them "will be able to spend Flynn's first Christmas there".
Bloom recently said: "I just don't want to be away from [Flynn] at all. Time with my son has pretty much gazumped everything else that makes me happy." He has also revealed that fatherhood taught him what "really is important" in life.
