Us kids we talk in english and we HAVE call each other by apa, baji etc
Now when i hear my younger siblings call my name i find it odd and so do they!!
It's the opposite with us, my younger brother has always called me just by my name and my parents have never asked him not to. My mum never calls my dad by his name but she does say 'tum' to him, we aren't a particularly formal family and when I've asked my dad why she doesn't just say his name as well he says he doesn't mind what she calls him lol in their case it's just her habit and what she feels comfortable with..
Me personally, I would never put my husband on such a high pedestal by refusing to call him by his name, I know in Islam we are meant to give him respect but we're also described as being 'garments' for each other which to me implies that that respect goes both ways, the idea of me not being 'allowed' to say his name just seems ridiculous to me, I'm not some Hindu woman who's going to bow at his feet and treat him like some God..
