( PEOPLE.com ) -- Miranda Kerr was all smiles as she left the Stella McCartney show at the Opera Garnier in Paris on Monday morning , but despite her cheery disposition , she says juggling mommyhood and modeling is no easy task . `` I 'm still breastfeeding so I have to express milk and send it back to [ 9-month-old son Flynn Christopher ] , and then try and see him on my breaks , '' the Australian model , 28 , told PEOPLE as she left the show , one of many she has walked in during Paris Fashion Week . But luckily husband Orlando Bloom is usually on hand to help out , especially when it comes to diaper-changing duties . `` He loves it ! But seriously , he 's very hands on . I really could n't ask for a better dad . '' Having recently left Paris for London where Bloom is promoting his new film `` The Three Musketeers , '' Kerr admits she 's already looking forward to being reunited after the shows and getting some much-needed sleep . `` I was up for hours last night as he 's teething . And when he 's crying , he just wants Mommy ! It 's such hard work . '' With McCartney 's four children backstage , the model spotted a possible future daughter-in-law . `` It 's funny because Stella 's little girl Reiley is almost the same age as Flynn so watch out -- Flynn might start dating her , '' she said with a giggle . Might their own family might be expanding anytime soon ? `` Not yet but let 's see , '' she said with another big smile . See full article at PEOPLE.com . © 2011 People and Time Inc.
