As the whole smacking debate has kicks off again I was just thinking: when you're around other parents, what are the subjects you dread/avoid like the plague/like to get on your high horse about?
I guess for me it is discipline (though not usually corporal punishment), and gender-based stuff. ('Oh, you've got girls, it's easy for you' etc etc.) More fraught when they were babies, I suppose: routines, weaning, breast vs bottle, etc.
Oh and the whole working mum vs SAHM thing; I'm always sad when there's tension between the two but it does seem to happen (I'm a part-time WAHM so I tend to sit on the fence and observe ...).
What gets your back up?
