Is this US or EU or somewhere else? I have some experience in Europe. I (male early thirties then) once was sat in an exit row (replaced with some other passenger) when flying EasyJet. As I understood then only because I seemed to be more fit to sit there. Once travelling with Ryanair stewardess exclaimed that "oh no you will be sitting with a baby in an exit row". We said "no no we are sitting the row behind". She said "thanks god I thought I will need to rearrange passengers". Of course a baby in an exit row MUST be a big no no anywhere. So I have a feeling that it is being looked quite seriously.
