Bag gurus.... I'm going back to work after a years maternity leave and would like a new bag. I'll be doing three days at work so would like one that doubles as a changing bag so I'm not constantly moving stuff between bags. I like a nice quality bag and it doesn't need to be super smart and am considering one of the plainer changing bags like the babymel Compton but is it OK to have a changing bag as a work bag?! I've got about £100.
