Now I don't mean to their kids - my kids call me mummy and I refer to myself as mummy to them when relevant.
BUT it really grinds my gears when adult women refer to themselves as 'mummies' to other adult women. Try and arrange a night out with the girls; it's a 'mummies' night out; introducing yourself to another woman at playgroup; 'Hi I'm X, Y's mummy; talking to about parenting on social media; 'becoming a mummy is the most amazing thing ever' - blah, blah, blah.
It drives me crazy. I don't know why. Maybe it's just so childish and twee. I can't stand it. Can't say I've ever heard dads referring to themselves in this way. AIBU?
