Australian supermodel Miranda Kerr and her husband, actor Orlando Bloom, often argue over who's going to change their son's nappy.
The couple welcomed baby Flynn in January last year. Kerr says she is impressed at the interest Bloom takes even in the less desirable tasks of parenthood.
"It's wonderful, Orlando's so hands-on," she said in an interview with British publication Fabulous. "He likes to get in there and do as much as he can. I'm very lucky. We love it - now we argue about who's changing the diaper!"
Kerr, 29, said becoming a mother had changed her and these days she puts her family before her career choices.
"I made the decision to spend 60 per cent of my time with Flynn and 40 per cent working, which means I'm very picky about what I will do," she said.
"And I make sure it works with the family. I'm at my happiest when I'm with my husband and my son. Waking up with my son and my husband in bed - there's nothing better."
