It was a Friday afternoon and I sat on the train, heading home, when a woman across the aisle got my attention. Excuse me, she said, did you just take your baby to work with you? It's just that you are dressed as if for work... She threw a look at my tailored trousers and at my red patent high heel shoes as if to illustrate the point. I smiled. My five week old baby daughter was strapped to me in a BabyBjorn and fast asleep. Her angelic face relaxed and tilted towards me.
