I did think that at the time but I decided we'd be more likely to run into her Mum in the main thoroughfare.
I always try to teach my boy to find someone with a pram to ask for help. It's a catch 22 isn't it. I made sure I was quite loudly saying "can you see your Mummy anywhere?" So as to draw attention to the fact that I was actively trying to locate her mother.
It's a shame that that even needs to be considered.
