I'm not a frequent poster but feel compelled to add my tuppeny worth to this (somewhat) over emotional thread, though I think whyfrank has already summed up my thoughts very well!
Deckthehugewithboughsofmanatee "To me it feels like denying or minimising a hugely important detail of your relationship with your children. They're not elective friends, they're your offspring. I think that's important to acknowledge, and would wonder what experiences had led someone to think this relationship wasn't one they wanted to draw attention to."
REALLY? I think you may, in your speed to don your finest judgypants over a completely trivial issue, have totally misunderstood people's motivation in not getting their kids to address them by their formal titles.
My sister and I grew up calling our parents by their first names, they never told us to, or insisted on it, they just never referred to themselves as Mum and Dad so we called them what they called each other (disclaimer: we are from Irish stock, perhaps this does have some bearing? Although I do remember our Irish relatives thinking it was a bit weird and we were the only kids we knew who did this). We both have a great relationship with them, filled with mutual respect. In fact, I might even go so far to say perhaps our good relationships with them as adults is due to the fact not only do we see them as Mum and Dad but also as people in their own right (and to me, their first names are synonymous with mother and father anyway, these are only words you know, it's the relationship that counts) When I later went into business with my mother, it was very useful not to have to call her Mum in front of the clients...
When our daughter was born, we decided not to tell her what to call us, and sometimes she calls us mummy and daddy, and sometimes by our first names, which is fine with me. I really don't need a title to feel like her mother, or do you all think I should ask my DH to call me "Wife"? Our DD2's first word was my name (that should shock you all rigid) To me, her calling me by my name is equally sweet and magical (or dare I say it MORE) than the generic "Mum".
Our children call my parents by their first names too, and have a great relationship with them. So as far as I can see, what they call us means sod all. By the way, we never called any of our other relatives by their titles either, and I'm not even that mad keen on "Uncle" and "Aunty", but I guess that's another can of worms, eh?
