So this has been said to me a couple of times now, and I am confused. I promise that the next time someone says it I'll ask what they mean, but for now, mumsnet thread!
AIBU in thinking that there's no sort of marker for a mother of boys or girls? What does a mother of girls act/dress/speak like? How am I falling so short as to be unbelievable?! 
Maybe it's the fact I have a 6yo DS too. Maybe he's polluted my 'mum of girls' vibe 
What do they MEAN?
